A member asked:

I have a painful and reddening lump in my armpit. what could it be? (i am 240lb male age 27 and recently have been biking)

A doctor has provided 1 answer

Abscess...: First thing that comes to mind is an abscess. These are very common in the armpit area. They're painful, red, and get bigger over a few days. It could also be an enlarging sebaceous cyst. Make sure you see your doc soon, and get it checked out!
