Almost 2 years ago, I moved down to Georgia from Michigan... I'm saying this because it's a change in climate and I don't know if that's why I have these bumps and around the time I arrived, I started to get these red itchy bumps, at first I thought it was the detergent I used or if I wasn't washing my underwear correctly because I didn't have a washer & dryer at the time so I was hand washing my clothes. So from then until now... I still don't have a washer and dryer but I do go to the local laundry mat. I have NEVER had sex (I am 16) in my life so I really don't think it's a STD or anything like that, I hope. BUT, that's not the only thing, I'm also getting bumps on my buttocks, they hurt, and they turn black when they stop hurting. I really want to know what is going on, I haven't scheduled a doctor's appointment yet because my family just doesn't have time or money for me so if anyone can tell me a certain type of cream I can buy, or just provide me with information on what this is exactly and I guess I'll have to take care of myself when I get a job .... please help me.
