I am female and 15 years old. I was recently self-diagnosed with a pilonidal cyst (both parents have had them earlier in their lives), but when I went to my pediatrician, she said it was some kind of abscess with staph infection (without swabbing the area, she only looked at it). She prescribed antibiotics and said that I should bathe once weekly with epsom salt. However, over the past 4 days, the infection/abscess/cyst has gotten much worse: although it has not begun to drain, it has gotten larger, redder, and the pain has increased significantly. I don't know if I should go to another doctor or just keep with the treatment.
