My apologies for the long posting:

I have been suffering with neuropathy type symptoms for over a year. I have constant tingling/burning in my feet, shins and forearms. The neurologist first diagnosed me with peripheral neuropathy, but the tests (skin and nerve conductivity tests) were all negative as well as the muscle tests were normal.

The neurologist concluded that I had post viral syndrome because my symptoms started after I had the flu. I was prescribed an anti-viral drug (Amantadine) that seemed to work until I got the flu a second time in December. I took two more courses of amantadine for a month at a time. This time, my neuropathy didn't improve and it has gotten progressively worse. I'm taking 1,600mg of gabapentin a day and it doesn't help.

Since I had gotten the flu twice in one year I sought the help of an immunologist. It turns out that I have low Igm. (IgG and IgA are normal). My serotypes are also not responding.

Has anyone found a connection with low immune response and neuropathy?

I'm also wondering if I should have the neurologist repeat some of the tests.
