I too am worried about the heat. When I get too hot now, which is quite regularly, I get nausea every time now. I am so worried about it-I went out the other day and it was about 80 degrees and had some errands to do and I got sick just like that. I got some throw up bags from the dr to keep in the car in case I get nauseated while.
I went to Sports Academy and got those cooling towels for the summer hoping that will help me.

I normally would have no temp problems but now can’t go out in above 20c or feel ill but my main problem is PURPLE feet and lower legs which remain ice cold even in warmth. In summer still bed socks and hot water bottle. Get episodes of feeling faint on getting up.
