I get Uhthoff's phenomenon in my eyes sometimes when I take too hot of a shower, but not every time. (not sure why that is) but, it hasnt bothered me so much that I've stopped taking hot showers yet.

My neuro said as long as I feel fine after taking a hot shower that it's ok to keep taking them. The vision problems (so far in one eye) are annoying, but it goes away within a half hour to an hour, so it hasnt been too bothersome for me yet.

The vision problem is the only one that I've had after taking a hot shower...if the heat from the shower starts doing other wacky MS stuff to me, then I might turn the temperature down a bit.
