I just barely noticed a lump on the same location. I have the same problem with the person before me. I also have no insurance and the lump did grow a little before the night I noticed it. As of this moment it's probably the size of a marble. I'm a little worried. It hurts only if I put pressure on it. I have never had a boil within that area but then again I'm only 21 and my body must be changing.
