I know when I get hot, I instantly look for a way to cool off because I know that it can trigger my MS and get very ill. I do not know about bringing on an anxiety attack but I pour iced water on my head or anything else to cool down.

Oh yes! Every time I over heat xXx

yep i have

Everyone is different I do get anxiety attacks my ms symptoms get worse when I get stressed and or overheated

I haven't had anxiety attacks but every thing else to do with heat ,stress running a tempter, bright sun, drinking something hot, the cloths am warring, thinking hard, working harder then I should, hot showers or hot tub I have taken this crap to extremes my body eater locks up or turns into a vegetable
