Yes , I gave this problem too. Can’t take heat at all.
Even though I can’t maintain a steady body temp, and am constantly trying to do so, it’s the heat that literally makes me ill. I do get some weird nervous system type stuff with the cold though, but I prefer that to the major symptoms I get with heat.
Someone mentioned that heat makes them more sensitive to odors - me too! And can trigger my chemical sensitivities . Ugh.
I spend all winter dreading the spring & summer... haha. I used to like heat, not anymore!
