I'm 19, around 5.9. About 12 stone, not really any medical history...
I have a strange lump like thing under the skin, on my waistline. I think it may have been a spot, i'm not sure. It hurt at times, I thought this was just due to the location and the fact I sit a lot putting pressure on it. It gradually subsided to a barely noticeable lump, however theres still a spot like mark there. But its been there for months now.... It looks like spot under the skin. But as I said, its been there for atleast 4 months or so.
