Hard lump under skin-Bikini area
I'm 19 and I've been sexually active with my boyfriend for the last four years and we've always used protection. I've never cheated on him and the only other guy I was with was about 2 years before my current boyfriend. Friday, 12/13, I discovered a small hard lump at the top of my bikini area. I haven't shaved in about 2 to 3 weeks. Its at the top left corner in the crease where my thigh meets my pelvis. Its slightly red and has some smaller, pimply bumps along the side in the crease. Its probably about the size of a small grape and it doesn't hurt at all but I'm concerned. My brother had testicular cancer and breast cancer runs in my family. I've never been tested but I don't believe I have any STD's or STI's. I've gotten pimples down there before but they're usually down further and I've never had an ingrown hair down there before so I'm not sure what it's like. I'm just really worried and I'm hoping someone can give me some insight. I'm going to wait about a week and go see a doctor if it doesn't get better but I'm just hoping someone can tell me if they've experienced this problem and if its just a serious pimple or ingrown hair. Thanks.
