Also couldn't resist a quick reply.

Exercise definitely seems to make my symptoms worse. I went for a fairly long (for me) run this week. The next day, at work, my usual symptoms (fasciculations in calves) spread to my feet, groin, shoulders, and abdomen--along with a horrible sensation of prickling and tingling all over my lower body.

My neurologist insists that activity cannot make the neuropathy worse, and is overall a good thing. That said, at the very least in the short term, exercise seems to aggravate damaged nerves.

Incidentally, my first ever symptoms (last fall) began when I started a vigorous exercise program. My first symptoms were tingling in my fingertips, which I associated with my new program of weight-lifting.
