For the last few days I have been in pain, I noticed that under my armpit there was a bump at first and then, a big red rash the next 2 days after. I do know the rash was caused from wearing tight clothing. Due to the fact the next morning I woke up with the rash. I thought it would go away after a few days of wearing lose tees but no, it’s still the same. I was wondering if any of you know any lotion or ointment that can make this go away. It hurts to move it and I’m scared it’s going to make my job hard to do. I need help treating this ASAP. Thanks for any comments below in advance.
