Hi, may I answer your health queries right now ? Please type your query here...I am 60 years old, 5'4", 186 pounds. I have recently lost 68 pounds. I have recently had problems with rashes. First I got what I thought was mosquito bites on my forearm, but they ended up looking more like spider bites, and became red itchy weeping bumps. They healed, then I got a red place on my face, which my doctor said was cellulitis. I took antibiotic and it cleared up. Then I got more rashes on my face, which the dermatologist said was a contact allergy to something. He gave me a topical corticosteroid. They have partially cleared up. However since then every time I exercise, I get red itchy bumps on the same side of my face as the original rash. Why would I break out after I exercise?
