I have a rash that has developed on the inside of both wrists and the inside of both thighs. At a lesser extent, the rash is spreading to my belly and chest, ellbows, upper arms, chest, and lower back. I first noticed the rash 6 weeks ago when I was traveling in Ohio.. At first the itchy sensation was not bad but for the last week it has been hard to sleep. I feel like bugs are bitting me. I started taking antihistamine to ease the itching. Also I am applying a eczema cream and have tried cortizone with little effect. Any ideas?
