You need a doctor to spell out your work restrictions and or limitations. Again, having a Functional Capacity Evaluation will help your doctor/s determine what those restrictions and limitations are.

this is excellent advice. this is actually crucial to your case. it cant be stressed enough.
In my opinion you need a positive evaluation by a neurologist to help
win your case.
A GP may be ok to treat the pain of peripheral neuropathy, however a GP is not going to carry the weight of a neurologist in the evaluation of a neurological disease for your appeal or hearing.
