Hi there, I am 22 years old and I would get serious Hive allergies on the areas that are exposed to the sun whenever I step outside as short as just 15min. After an hour indoors, it would cool down and be normal again. I dont think its sunburn. This occurs only in the morning and aftenoon, but at night-time when its cooler I'm completely fine. I went and did some tests with allergy specialists, and turns out i was allergic to grass, pollen, dust..etc And they said theres nothing they can do =___= ; This problem started only 2 years ago, and i was totally fine before then =/ and its been bothering me alot because I cant do any outdoor activities. I try taking Antihistamine and wear long sleeves + pants to avoid this problem in the meantime. But if theres anything I can do to help boost my immune system or fix this problem in the long run, please let me know! Thankss!
