--Lyme is a known generator of neuropathy, even if the infection was "cleared up". It is, of course, notably difficult to accurately diagnose Lyme---it likes to hide, and mutate, but if you had a positive diagnosis, it's certainly possible that a lot of your neurological symptoms stem from this, even "post-Lyme" (if, you are indeed post-Lyme--it is also difficult to completely eradicate).

You should search out some of the post by Lizajane here, who has gone through her own battle with Lyme, concurrent infections, and misdiagnosis. And also take a look at the Columbia University Medical Research Center for Lyme and Tick-borne diseases:
