I never had an allergy to anything before (not even Poison Ivy) in my life, and suddenly I develop this terrible allergy to the sun, along with several other alarming symptoms. Here's what happened. I was at a camp for a week very I received a lot more sun that I typically do. For the first few days I found it odd that I didn't burn or get tanned ( I usually do), and then the next day while in the sun all of my skin is red and hot. In the beginning I thought that I just had a particularly bad sunburn until it began to itch like crazy, and I went to the first aid place. They gave me some Benadryl and let me stay in there for a few hours and the rash went away(in retrospect I think that it was being away from the sun that made the rash go away rather than the medicine). Then as soon as I went outside it broke out again. That's been happening ever since( it's been a week), but I have some more alarming symptoms. Firstly, I have been getting injured in ways that are so tedious that I wouldn't ever conceive them as dangerous. I somehow hurt my knees and back just by running( I run a lot and this has never happened).I also have been getting sores in my mouth like crazy ( I never used to get them at all). Does anyone know what is going on? Also, I have went to the doctor and see told me to take Zyrtec ( and she prescribed me Zantec ( I don't know what heartburn meds do for allergies?). This hasn't helped me at all and in fact the problem has gotten worse since I have been taking these drugs. I have a follow-up appointment with her in 2 weeks, but she didn't spend hardly anytime asking me questions and just gave me these medicines and left. Worse, she has been my family's doctor for a long time so they feel an attraction to her, and I can't go anywhere else. Sorry for the long post, but what should I do? Edit: I've attached some photos. AT the time of shooting I had been out of the sun for around 4 hours, so some of the swelling has gone down.
