i have had a rash on my arms, under my arms, my lower stomach, my thighs and behind my knees. it has been there for 4 weeks. i thought it was poison oak but have tried creams to clear it up and nothing has worked. now i have red blochy places all over the mentioned areas that itch so bad. i have scabs that itch. it doesnt look like its gettin worse, but its not getting much better. i am so tired of scratching and creams on it. i have used benedryl, tecnu lotion, zeaborb powder and have taken benedryl by mouth. i had this in oct 09, but not this bad. it was only on my legs and i do have scars from it. please help.
