Help. About 4 months ago, I developed an itchy scalp (no flaking), eyebrows, eyelashes and soon itchy bumps all over my face. Now, it's slowly moved to chest, shoulders and back. I've noticed it's where I sweat. Also, it clears up as it moves around. In other words, my face and chest are much better, but shoulders and back are new. I work out 5 days a week. Two one hour sessions of cardio make me sweat in all of these affected areas. Is it possible I'm allergic to my hormone replacement therapy and it comes out in my sweat which irritates? I've been seeing a dermatologist, but he has not solved it. Ketoconazole, hydrocortisone cream and ointment, dandruff shampoo, elidel and triamcinolone. None have helped. Any ideas?
