Hi everyone, i apologise if i am being silly and come across a little naive, im just really worried as all day ive had a kinda pain in my armpit, but thought when i got home and took my shirt off id just find a spot or bite or something like that. However ive taken my shirt off to find nothing there. So this lump is under the skin. Its not actually in my armpit, if you could imagine putting your arm in the air its maybe an inch above where you get hair? i hope you know what i mean. Anyway i look on all these websites for help or advice and havent really got anywhere as i dont know if this would come under breast, or arm or what?? Can anyone put my mind at rest, or the opposite..tell me to get to the doctors? if it was anything to worry about, how would it feel? Would it hurt as this actually hurts if i press it?
