Help! I've had hives for months and nothing is working!

Dude I have the same thing! Whenever I get too hot it's hives all over, and drinking water sometimes makes it spread up to my face and lips. Definitely VERY scary. I've tried double daily doses of zyrtec and Allegra to no avail. I currently don't take any medication daily and just do my best to avoid putting myself in those situations. A dermatologist will be your best bet for finding a solution.

if it's when you get super hot (aka sweaty) you may have cholinergic urticaria! I have the same problem with hives and itching that does Not go away. the only things that have brought me any modicum of relief are hydrocortisone cream and claritin. Prednisone works REALLY well but that's not a drug you can take all the time lol. try to keep yourself dry and see how that works, if it helps then otc allergy meds and antiperspirant spray may help you more in the long term

your hives sound like they're cholinergic (like mine!), meaning you get them whenever your body temperature gets too high. i use an over-the-counter hive spray that helps a lot with the itching and benadryl is also really helpful. being able to lower your body temperature when you need to could also help, like carrying cold water around with you. i would definitely talk to a dermatologist or allergist in case i'm wrong, though
