My boyfriend has this sharp long pinching pain in the nipple and armpit area it lasts for a couple minutes and then goes away. It happens every 1 or 2 months and he says it is super painful. It kinda is starting to worry me that it may be something bad. He doesn't wanna go to the doctor unless it is something serious cause then if it's something stupid he just waisted his money. Does anyone have any idea's of what it may be? p.s. only answer if you are going to be helpful and not rude.
