Hi my name's Justin. I've had a lump in my left breast for a long time,but it's never really gave me any trouble, sometimes it would ache. but now I have a pain in my underarm area, like it's my ribs or something, but sometimes I can put my deoderant on and it kind of hurts to rub the deoderant over my arm pit. I was just wandering if I should be worried, or could it be something to do with my ribs, like space between my ribs? My left armpit swells just a little but there isnt' really a lump, at least no different than the other armpit. I was just wanderinn if you could give me some advice. Thanks. Justin
