Need Help with Allergies and Exercise

I mainly get sweat flare up while I'm sleeping. Mostly where I sweat the most. When at the gym, I drink LOADS of water before and after each set, which helps immensely. I used to do thru hikes, no its less than 20 mile hikes due to flare ups

I’m also allergic to sweat. I can’t do anything more than walking :(

Same! It just sucks because I used to like to be active and any activity is just unpleasant now.

i have a condition called cholinergic urticaria, i get hives whenever i sweat. i take zyrtec, it helps somewhat, but i recommend wearing looser clothes, drinking water, and working out in cool places.
