Hi, my name is Kevin and I am 21. anyway Last night I discovered a pea sized bump under my armpit. Its not visible and dont ask me how i discovered it, who knows how long its been there. Anyway it is painless (that is until I rub my skin raw after touching it for so long). I know there could be a number of reasons for this lump, but how concerned should I be? I dont really show any other signs of anything serious, but the last 6 months I have had lots of back problems and unexplained headaches which I asked about in the headache section of this forum.

This whole year I have had health problem after health problem that I would tell my mom about (shes a RN) and she never seemed concerned... that is until today. So this has got me a little nervous. Im just wondering if I should be worried about this, or if I should wait to see if this lump goes away
