Nope not alone, I suffer many of the same symptoms, headaches, joint pain and inflammation, GI problems, sun allergies, rashes, ugh list goes on and on. My symptoms come in cycles.

I've been going to the dr for years, loads of testing, still no answers. Hopefully you find out. I'm 99.9% sure that my physical symptoms are not mental. However that really can cause a lot of physical symptoms. Good luck to solving this problem, it sucks to be sick, that's for sure.
