Dear wwwsss1: This is a breast cancer forum and breast cancer is our expertise. However, if this is a new lump, you should let your mother or father know and possibly be seen by a doctor. There is no way via the internet, that we can speculate on what this may be.
my thoughts, could be merca. both my little sisters got it in the exact same spot on different thighs, and my cousin got a staff infect on his arm. the twins had it easy. if it is merca, which we call the funk, then it would kinda remind u of a hangnail and a zit. So try squishing it, hard. if theres a knot underneath it, squish it out. thats my advice
