Way back when I was looking for a diagnosis, "stress" was considered as a possible cause for my symptoms (not just by my PCP, but also by me). I took a little getaway to North Conway NH, all by myself, a totally stress-free mini-facation.

It was mid-September, perfect weather--except no, there was a little heat wave. I was at the mall when I realized that I was having a real problem navigating, bumping into things, "wall-walking" in the stores, rubbery legs, brain soup.

That was the point where I knew, no, it's not just stress. There's something WRONG with me. I didn't know then that heat sensitivity was a common MS problem. I just knew that the hot weather was triggering problems that weren't normal.
