  Bilateral elbow pain and swelling  
       
  For about 4 years now I have had pain on the inside of my elbow--you know where they usually draw blood? It wakes me up at night and it swells. Sometimes there is a hard knot there. I have it in both arms but my right is the most painful. I have tried to find out exactly what is there that could hurt but haven't found anything. Any help would be appreciated.
 
       
  Answer 1 It sounds like a pain and swelling in both elbows, which does not go with a nerve problem. This is outside my specialty, however, I would suggest a consultation with Rheumatologist.
 
       
  Answer 2 I agree, this doesn't sound like nerve in nature. In cases like this, it might be tendinitis (the Biceps tendon is in that area) or joint disease.  
       
  Comment Thank you both so much--at least I have an idea now what to look for. I forgot to mention that sometimes the pain radiates down the inside of my arm to the palm of my hand--it feels like someone has ripped my arm open with a knife. Thank goodness it doesn't last more than about 30 minutes. Ascriptin AD helps a lot.
Thank you both very much.
 
   
       
  Cold hands and feet with tingling in arms and back  
       
  I'm writing this because I'm at my last end. My symptoms have been...nerve pain in my thighs and tingling, cold feet and cold hands. I recently have been feeling tingling in arms and back. The doctor has run ten and ten of test and I even went to a nerve doctor and he ran electric test and the results were all normal but I still have the pain in my thighs. This is really starting to be annoying. HELP!  
     
  Answer These symptoms, in cases like yours, could be caused by a peripheral neuropathy, a condition that can have many causes, such as diabetes, alcoholism, toxic exposure, metabolic and other nutritional conditions.

For symptoms such as yours, it is best to start with a good internist and then have them refer you to a good neurologist. Many things could be at the origin of these symptoms.

 
     
       
  Elbow brace wearing in ulnar entrapment  
       
  I just had an EMG and the Doctor told me that I had a severe pinching of the ulnar nerve. I have had numbness in two fingers since Christmas. Having difficulty picking things up and typing. He suggested I wear an elbow brace for one month and see him again. My question is what are the chances that a brace will work? Has it worked for anyone? Won't I be able to tell if it is working by the feeling in my fingers? If the brace does not work and surgery is required, how long is recuperation? We are going to Scotland to golf in April and I sure would like to be healed by then. Thanks for any information.  
     
  Answer EMG result should be taken into consideration, among other factors, before we could say anything about recovery time or surgery. However, in general if the ulnar nerve compression is mild then you would feel that brace works perhaps in a week or two by having less or disappearance of numbness. But if the lesion is severe, it takes longer time, months (variable according to severity), or it might not work then it is the decision of the surgeon.
 
     
       
  Partial hand sensory loss after fractured 5th metacarpal  
       
  My son was in an MVA fracturing the base of his fifth metacarpal on his dominant hand. Sensory deprivation in ulnar nerve distribution of right dominant hand below the wrist. Protective sensation absent, although NCV and EMG findings report nerve is healed. He is now having difficulty with 4th and 5th digital adduction and MP flexion with IP extension. If the EMGs and NCVs are normal what would be an explanation for his sensory loss and progressive motor loss? an aneurysm?  
     
  Answer I am not too sure whether the problem is in the ulnar nerve or digit bones. I am inclined from your description to say that it is NOT the ulnar nerve, as its study is normal. But to explain the sensory loss, it may be due to very distal lesion of digital sensory nerves that could be missed by standard studies.  
       
  Comment Thanks for your prompt reply; What test other than standard EMG/NCV would be appropriate?  
       
  Answer I would not have other tests or to suggest any. Just a careful neurological examination of the power and sensation should be very helpful to rule in/out any sensory loss or motor weakness.  
     
       
  Neck pain with upper limb radiation  
       
  I was hit by another driver 2 years ago and have suffered with neck pain, left arm pain from forearm to fingers, numbness in left hand and shoulder pain. I've been seeing and orthopedic doctor until recently when he ordered another MRI and it was normal. I was told to live with the pain or see one of the Partners. He didn't know where the pain was coming from. The first MRI showed three bulging disc in my neck. Before the recent MRI I was told I had a nerve impingement of neck. I'm frustrated and confused as to why a doctor would drop a patient that is in pain. I told him I would go through any tests is he would just find the cause of the pain. I had to go back to my medical doctor and she has referred me to another orthopedic doctor in the same group but she has ordered a nerve conduction test due to left arm numbness and shoulder pain. What can I expect? To left arm numbness and shoulder pain. What can I expect? Also, both MRI where open, is there a difference in the open MRI and closed MRI and closed MRI, as far as result?  
     
  Answer EMG and nerve conductions are helpful. They may show pinched nerve in your case. However, I would recommend consulting a neurologist as second opinion either before or after doing the EMG and nerve conduction studies. Regarding the open or closed MRI, I do not know.
 
     
       
  Shoulder/arm/hand/finger pain and numbness  
       
  I woke one Morning with painful R arm, (Mar 98) like if I had pulled a muscle. By the time I got to TX, my R arm was numb and painful, also like if it was paralyzed. I was over the road truck driver at the time but only for 6 months. I went to the Drs and after several tests I was told I had C5-C6 Slight herniated disk. So had the surgery in September of 98; the pain in my shoulder never did go away nor did the numbness in the hand. After several more tests I was told that I have impingement, so again after several physical therapy Sessions and no result. Surgery was done and about a half inch on bone was taken off of the shoulder. That was almost a year ago and still pain in shoulder and numbness in hand. Now it is in the left hand (numbness) involving the pinky, ring and middle finger, which go up to the elbow area. Although this numbness is more like a sleeping feeling, but is constant and so far no matter what has not gone away. So again more tests EMGs X-Rays and possibility of MRI and CT scans. I have had bone scans and arthritis has been ruled out. What is a DMG as that has been mentioned? I'm 45/female and normally very active.  
     
  Answer I do not know what DMG, but probably you meant EMG (Electromyography), which is a test for nerve and muscle. You will find details in the previous emails, particularly the last one. Anyhow, from your symptoms (left side), it is likely that you have pinched nerve, hence EMG is requested as well as other radiological studies. All the best.
 
     
       
  Really painful muscle fasciculation in my thumb pad involuntary twisting & CTS  
       
  I had a EMG/NCS (Needle) (Nerve Conduction Study) in Jan, and I did go see a surgeon, and they want me to have surgery again, but I am hesitant. I went through a lot back in 1994, and had to give up a good job because of all this. I had bilateral Carpal Tunnel Syndrome surgery, and a right DeQuervains syndrome surgery with a ganglion cyst removed at the right carpal tunnel region back in April 1994. My right hand has not been the same since. My Left hand recovered fine. For the past few years, it has been getting progressively worse. I worked in a factory as a machine packer, packing 300 sweet-tarts per minute, and picking up / gripping (using my index finger and thumb) each box putting them on the conveyer belt. I developed DeQuervains syndrome, CTS, and a massive ganglion cyst due to this repetitive work. My doctor diagnosed me with repetition motion syndrome. I stayed off work for 6 years due to this injury. I figured I would try and find a job this past year, and work part time. I wanted to gradually get back to work, and get use to using my hands again. The job I took was just part time 4 hours a day doing light data entry. That is when I started noticing my right thumb having really painful muscle fasciculations in my thumb pad. At times, my right hand and fingers started having really painful charlie horse symptoms - thumb cramps - sudden tightening of the thumb muscle involuntary twisting movements, and uncontrollable thumb motions. I find it challenging to drive a car, open doors, pick up my grand daughter and a lot other daily activities are almost impossible. I recently talked to my doctor about the problem, and she sent me to have another EMG. Conclusions were 1. Mild to moderate delay of right median motor and sensory latency consistent with right Carpal Tunnel Syndrome. 2. Chronic denervation and giant fasciculation suggestive of injury or continued irritation of right distal median at the wrist of the branch to thenar muscles. The problem I'm having is in my thumb pad and my ability to grip, hold and open things. I am having really painful muscle fasciculation in my thumb pad. At times, my right thumb pad starts having really painful charlie horse symptoms -thumb cramps - sudden tightening of the thumb pad muscle involuntary twisting movements, and uncontrollable motions of my thumb. Any reason I may be having this? I did have another Carpal Tunnel Syndrome surgery, on Feb 13, 2001. I know I should not expect too much this soon, but I called my doctor because my thumb pad is still twitching and jumping around and having thumb cramps. He is telling me I have a rare condition and he is not sure how to diagnose my condition. He wants to send me to another Neurologist. I do feel my Carpal Tunnel Syndrome will be better with the surgery I had. He said I had a lot of scar tissue, and that was probably my problem, but my thumb pad is still painfully twitching and jumping around. I just wish I could find out what is wrong with the twitching and cramps in my thumb.  
       
  Answer 1 It seems like you need to wait for possibly few more weeks to see some improvement because your condition is chronic. Now, if your surgeon is also suggesting a neurologist, then go ahead and see him.  
     
       
  Thoracic Outlet Syndrome  
       
  I just wish I could find out what is wrong with the twitching and cramps in my thumb, and was hoping may be someone could let me know if they have ever heard or seen this condition before. Today I went to see another doctor to get my stitches out, and my fingers were ice cold and were blue and purple and had no feeling in them. The new doctor said he talked to my other doctor and a few other doctors and they all think I have Thoracic Outlet Syndrome. He noted that's what he was thinking I had. He said after reading my report, and seeing me today he is almost positive I have Thoracic Outlet Syndrome, and trying to locate just how far up my arm it goes. Right now he wants to give me some time to heal, and wait a little longer before he goes any further. I just had high hopes in this surgery, and guess I just need to give it more time. Just Looking for answers.  
       
  Answer The combination of CTS, which is a distal lesion, may rarely be associated with a Thoracic Outlet Syndrome (TOS), which is a proximal lesion of brachial plexus. The finger skin changes supports that. EMG can also occasionally help to confirm that. Whether to advocate for TOS surgery or not and when, this is a surgical decision. The surgeon should make sure how much benefit the patient would get out of the surgery.  
     
       
  Role of cortisone injection for intense neck and head pain accompanied by arm numbness  
       
  I have been reading your forum messages on arm, neck and shoulder pain. I had C5-6 fused in '98 and continued to have severe neck and head pain to this day with numbness in my arm. My physician (neurologist) is treating the situation as the effects of surgery in the area with pain killers that are not very effective. Physical therapy only seemed to be limited help for a short while. I sought another opinion. The second neurologist has suggested a cortisone injection to the nerve in my neck to stop the pain which was viewed as a possible pinched nerve. I have also been experiencing "dropping" of things from my left hand. I have not seen this injection listed in any of the forums as a possible answer to the pain. I am scheduled to have this done in about a week and a half. Is this recommended?  
       
  Answer Cortisone injections reduce the swelling which may be causing the pain symptoms but do not treat the cause of the swelling. It is also useful to have an EMG in instances such as yours to find out if there is still any nerve damage and the extent and location of it. Carpal Tunnel is to known to cause the dropping of objects from the hand.
 
     
       
  Is surgery sufficient for treatment of DeQuervain’s syndrome  
       
  I was recently diagnosed with DeQuervains' Syndrome on my right hand. I previously have had carpel tunnel release surgery on both hands. My doctor gutter splitted my wrist and I can't use my right arm for 3 weeks. I guess my question is this, After the 3 weeks is over, Is there usually more treatment and therapy involved, or does the split take care of the problem??  
       
  Answer 1 DeQuervains' Syndrome surgery should take care of your problem. However, physiotherapy is usually done afterwards. Orthopedic surgeon decides this.
 
       
  Answer 2 You can learn more about DeQuervain's Syndrome by going to our main page, and clicking on the Patient Education Material link, which will take you a list with the DeQuervain's Tenosynovitis link.
 
     
       
  Long thoracic nerve vs. dorsal scapular in asymmetric scapulae  
       
  I have an asymmetric scapula that is low and prominent at the inferior medial edge and looks farther away from the spine than my other scapula and causes me lots of pain and problems. My EMG showed a single repetitive discharge from the LTN at the end of the test. The tester thought that clinically it didn't seem to account for the way my scapula looked. I also showed moderate to severe weakness in all muscles tested on the right side of my back-scapular region. My rhomboids and levator were also tested. This has been ongoing for 2 years and I am quite impaired by the problem. I really need help to figure this out. I am not improving and although my scapula is not a typical textbook example of winging I have pain and weakness down the arm, and pain and looseness around the scapula. Could I have some dorsal scapular nerve injury too that is simply hard to find. My trapezius also looks a little sunken in on that side. Thanks  
       
  Answer Sorry for delay in replying. Now, winging of scapula can be due to long thoracic nerve or dorsal scapular injury. It depends on findings clinically and EMG. However, in your case you mentioned that trapezius is sunken a little, this muscle is not supplied by either nerves. This is against those possibilities. I think good neurological examination should help, but we should keep in mind that injury of nerves not the only cause of winging scapula. All the best.
 
     
       
  Axonal Peripheral neuropathy  
       
  Need help understanding EMG report - please. Ending comment states abnormal EMG exam & nerve conduction studies. Two problems noted - 1) Mixed motor-sensory - but principally sensory neuropathy. With decreased amplitude & normal latencies - axonal in form. Changes shown by low-amplitude conductions and on motor side by marked increase in irritability distally bordering on denervation. Patient also has bilateral carpal tunnel syndrome with prolonged median sensory & palmar latencies. Can anyone put this in non-medical - simple English terms? Having problems understanding what is meant by "decreased amplitude & normal latencies" and also irritability distally bordering on denervation. Is this bad? Also, does anyone know where you can obtain standard nerve msec readings - for instance I have 4.1 msec for sensory distal latency - how bad is that? I really appreciate any and all help on how to understand what is going on.  
       
  Answer You are not alone in your confusion in interpreting this report. You definitely need to post more of the data (amplitudes, latencies and conduction velocities, as well as needle EMG results) to be more definitive. To answer partially...
1. Your nerves are built somewhat like a piece of wire, an insulating outer layer (myelin) and a bunch of small wires on the inside (axons). In general, if the myelin is being affected by some process, the conduction velocity will be slow and latencies will be prolonged. If the inner wires (axons) are being affected, the amplitudes of the response recorded are decreased. The description would indicate that you have some widespread process affecting the axons of the sensory nerves, although without the data I hesitate to say this.
2. The sentence about "marked increase in irritability ..." makes no sense. Sounds like a reference to the EMG study (the needle part) but I can't tell.
3. Normal values are dependent on many factors (technique, temperature etc), so again this is hard to comment on. Generally, 4.1 ms across a 14 cm distance (a typical distance for a distal sensory latency) would be mildly prolonged (but some reports would call this normal).
Confused yet? Again, need more data to be more definitive. Hope this helps.
 
       
  Comment Thank you very much for your initial response. I didn't know how much info to give as I am new to all of this but in a nut shell here is the report:
Results: Upper extremities-Irritability was normal, without fibrillations or positive sharp waves.
Lower extremities - Irritability was markedly increased in the intrinsic muscles of the feet with runs of positive sharp waves on needle insertion, but none were sustained with the needle at rest. Irritability elsewhere was normal.
Nerve Conductions: Right Median Nerve - Motor distal latency at 8cm was 4.1 msec; Sensory distal latency at 13cm was 4.1 msec; Palmar sensory latency at 8cmm was 2.6 msec
Left Median Nerve - Motor distal latency at 8cm was 3.0 msec; Sensory distal latency at 13cm was 4.2 msec; Palmar sensory latency at 8cmm was 2.8 msec
Right Ulnar Nerve - Motor distal latency at 8cm was 3.1 msec; Sensory distal latency at 13cm was 2.9 msec
Left Ulnar Nerve - Sensory distal latency at 13cmm was 3.1 msec
Sensory responses for the ulnar nerve were moderately reduced in amplitude and median responses were markedly reduced in amplitude.
Right Sural Nerve - Sensory distal latency at 14cm was 4.0 msec
Left Sural Nerve - Sensory distal latency at 14cm was 3.7 msec
These values were obtained only by the use of averaging techniques and were markedly reduced in amplitude.
The balance were the comments mentioned initially. The patient is my husband and he has been exposed to chemicals at work which we believe is the cause of the peripheral neuropathy as he is not diabetic and has never been a heavy drinker. He is 49 and has been very healthy his entire life - until now. He works construction so has worked hard and while thin is very muscular. He does have allergies (dust, grass, etc) but has also been found to have a 35% loss to his lungs. This was a 2nd opinion doctor required by the workers compensation carrier for a case that has gone on since July 1999. In seeing the various docs we are told that he has nerve damage and not much treatment other than for pain is available. His doc has told him that he is 100% disabled due to the constant pain in hands, arms, legs & feet and nothing to rehab him into. Obviously the W/C carrier wants to fight that diagnosis. The part of this 2nd opinion report that worried me the most was the denervation comment. From the tests in Oct 1999 & Feb 2000 it looks like the condition is getting worse as the numbness/loss of feeling is going higher up the arms and legs. Any insight you can give me is appreciated. (Sorry for the length of this note.) God Bless you!
