Hello I'm 15 and ever since I was 13 I have been having extremely uncomfortable itching and burning under my arms every time I sweat even a little. Whether it's when playing around and being active or getting in and out of the shower whenever I sweat it hurts really badly and since I was 14 I have been using a Degree Clinical Deoderant cream, because other deoderants caused even more burning, to keep the burning at bay but whenever I go to shower it comes back. I don't know if I have a disease or if this is just a simple rash but I've had it for ears and I was wondering if there was a way to get rid of it. Help. :'(
