I'm sorry to hear about your condition, but I would like to reassure you that exercise is actually a good idea as part of the therapy for your issues and overall health. I'd recommend that you start with plenty of stretching and progress your routine slowly. It would also be advisable to work with a certified trainer who is experienced in the management of clients with your condition.

Having a background in physiotherapy before becoming a physician, I strongly believe in the therapeutic value of exercise. I also urge you to read the response written by Dr. Jay D. Makim, MBBS, MD. He has offered some useful tips and I concur with the opinions he gave.

I am so sorry you hve difficult issues to del with, but hang in there.

THere is No Reason, Not to do any exercises. Many times, a person feeling weak, is from NOT doing Regular exercises. Especially range of motion, and conditioning exercises, and start with small weight, e.g. 1lb, gradually increasing; but Not knowing the Extent of Your Neuropathy, any general medical condition (heart-lungs-kidney-liver-anemia, Electrolytes, diabetes, taking other medications, your weight, etc) may interfer with anyone exercising, and you should check with your Neurologist and combined with your general primary care doctor, come up with the plan, to best suit your health (neuropathy) and may need help from trainer. IT however does not make sense, if you have only Pure sensory Neuropathy, you should NOT have Fasciculations or Weakness of muscles, and should have proper check-evaluation, to find out and make sure there is no other cause for those TWO important ITEMS (WEAKNESS and Fasciculations). And if prior nerve conduction test performed long time ago, then consider new one, or see Expert In that Field (may be major university center). Other than that, proper diet, and hydration are important; time of the day-better keep fixed routine; duration of exercie-depends on your conditioning, tolerance and if any factor or issue I mentioned above. Hope you had full blood check, including muscle enzymes (CPK total and MM, Aldolase, LDH), CBC-chemistry-urine-ESR-ANA-TSH; EKG-if not done; EMG if Not done; other testing like MRI may also be needed-find if any family member have similar condition, etc. The Goal is to make sure you have proper diagnosis. Science has gone far and beyond our imagination and sky is the limit for properly diagnosing and treating.

Hope this helps you and wishing you best.

Since you say you have a neurologist, I assume you have had an EMG, appropriate lab work, and appropriate physical exam. If you have not had any of these, you need to have them done.

Weight training should not be contraindicated as long as the proper precautions are observed. Of course, start low weight and increase slowly as tolerated with the weights to avoid injury. If you have weakness in the arms, safety is a concern. Use of a spotter or machines with built in safety measures would seem to be indicated to help prevent an accident.

If you are ok running you will be ok weight lifting. Just don't hurt yourself if it is new to you.

Engaging in a strength and conditioning program including lifting weights is a great idea. I would start out with a trained professional in a supervised setting if possible. Also you mentioned arm weakness possibly related to your idiopathic small-fiber sensory neuropathy. Based on the weakness you are experiencing and unfortunately the potential for proprioception or your balance being compromised I would recommend using weight machines including cable machines and nautilus. I would avoid free weights at this time to avoid risk of injury. Overall the benefits from aerobic and anaerobic exercise including brisk walking/running as well as weight-lifting improve blood circulation which improves oxygen flow to the nerves. This is a great idea as long as it is done in a supervised setting with the guidance of your physicians.

This depends on your caution

Do it carefully

Because neuropathy could have symptoms of weakening suddenly

Lifting weight lying down should be OK

Light exercise is ok. But still should get electromagnetic gram study of nerve
