invisible rash
i have a itch, no rash but at night it drives me crazy . when the area is itchy i can feel tiny bumps, but when i try to see it the skin looks clear, wakes me up at night rarely bothers me during the day. it started at the back of my scalp, but can't see anything,, i have long hair and am afraid i will lose my hair in that area from scratching. Now it is on my legs and knees, yet i see nothing!
