What causes rashes under arm of a 12 year old for years?
Patient: My son aged 12 has rash down one side under arm along side of back. He has had this for ages and 2 lots of antibiotics have not got rid of it. The spots are red and sometimes angry looking where he scratches them but they are not itchy all the time. They have yellowheads and they scar. He has had them for almost a year and the blood test was non conclusive. Can you help thankyou. Doctor: Hi, can understand your concerns. Underarm Rash can be due to many causes like fungal infection, allergic Rash, underarm sweat Rash, early signs of HIV infection, Contact dermatitis or worm infection. I suggest you to do HIV test of child. There are some home remedies which you can follow like we are loose clothes, apply ice packs to reduce itching, apply Vitamin E oil on aloe vera oil, increase Vitamin C intake to reduce skin infection, swipe slice of lemon under your armpit to help kill bacteria. I hope this will help you. Take care.
