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
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.
