I have the "ping pong ball" look under one arm and it drives me crazy! Several years ago when I was about 25, a plastic surgeon told me he wouldn't remove it because it would cause too much nerve damage. But now after hearing how many of you DID get it removed I am going to look into it again. It starts to get sore and bigger about 10 before my period is due and lasts until I get it. Now that's a big chunk of the month to be sore!! I hate it!
