it is just red and sore. I have tried switching detorants but that didn't do anything, I am mostly wondering what it is and how I can make the bumps go away.
Could be hydradenitis (sometimes spelled Hidradenitis). If so, hot compresses might help but for me tetracycline and shots/drainage in a dermatologists office were the only things that have worked. I hope you don't have it. Good luck.
You should avoid using a deodorant directly to your under arm skin, avoid shaving or waxing the area for some time. These could be the cause of your symptoms.
