So I have this colorless bump at the very end of my thigh, it hurts when you apply pressure. I'm starting to get worried. I also been having other symptoms, I'm not sure if it's the same case but there been black dots appearing around my body lately, there little black dots, like very little. It's like acne. Except very little. And you could pop the out. And I had these bumps around my butt too. I don't think it's STD because I never had sex before. I'm so worried, please help
