I get it all the time. My cousin actually gets it SEVERE. I can tell you if I switch deodorants and I to alot of work with my arm rubbing my side it can get irritated too. Some times it does it on its own and it will be a small spot the size of a nickel but it will be very irritated almost burning sensation. Its very common to get underarm red areas and irritation. It will go away dont worry. If its not killing you pain wise, I would jut let it run its course. L8Er
No this is the first time i got these and i never used any deodrants.
sounds like and irriated or ingrown follicle. has this ever happened before? have you changed deodorants?
