Not to my knowledge, I''ll ask him. Think this was just a diagnosis based on symptoms.
Well don’t settle for a diagnosis based on symptoms. Get him to a neurologist and let the neurologist make a proper diagnosis.
There are so many causes of neuropathy (as can be seen from this thread) that you need to try to nail down a reason for the neuropathy. If it is from a disease, then you need to know that. If it’s a vitamin deficiency, or medication related, from trauma, or hormone induced that needs to be checked out.
Neurologists can help nail down a cause through various forms of testing.
(I have MS...I don’t have neuropathy, but have symptoms that could be mistaken for neuropathy but are a result of damage to the CNS not peripheral nerves.) Not saying he has a disease, just saying it’s important to find out the reason he has the neuropathy.
