Rash on upper part of leg
I already have a permanent rash on my neck and face. But since May when my legs got sunburnt--not intentionally, it has left the whole sunburn red mark in that area on both legs. It's right above the kneecaps on the skin in the same areas on both legs. It has never went away. It always makes it worse after a shower or being in bed.
Is this another symptom that my skin is again once damaged? Why doesn't it go back to normal color?
