Underarm Rash

I have had bad rashes under both arms now for about 2 months but haven't thought much of it. They are a pink/red/purple color and they seem a bit dry (but not much). They don't really irritate me most of the time unless I am wearing a shirt where the seam rubs into it a lot and then I will notice it much more. The other thing is when I have put deodorant on they look better. What is going on?

Hello,
From the symptoms intertrigo needs to be ruled out. It most commonly occurs due to bacterial, viral or fungal infection. An intertrigo usually appears red and raw-looking, and may also itch, ooze, and be sore.

Please keep the area clean and apply some topical antiseptics. Also wear loose-fitting cotton clothing and use an antibacterial soap or mild soap like dove. Avoid any kind of cosmetics. Topical zinc oxide cream like Sudocrem, Desitin are very helpful(apply with a paper towel and not directly with hands).Application of mild steroid cream like dermacort also helps. For the itching please take some over the counter antihistaminic like benadryl or Claritin. In case the symptoms persist then antifungals may be needed. Please consult a dermatologist in that case.

I sincerely hope that helps. Take care and regards.
