I have to agree with everyone, we all do not react the same to sun exposure and stress. I never get rashes from the sun, but I do get the horrible muscle aches and joint pain and when stress is added to the mix, I feel as if I'd been run over by a train. Oh, and don't let "overexertion" get added into the mix..it is a recipe for "flat-on-you-back" days.
I know that it is difficult to deal with this current flare-up. However, we all use our flare-ups as learning experiences in order to help us know exactly how this disease affects us and what we need to do, individually, in order to avoid another such flare up. I do hope that you start to feel better soon.
Peace and Blessings
Look For The Good and Praise It!
