Suggest Treatment For Scoliosis

I am a 21 year old male in college who has been having back issues my entire life. Currently, I do not have health insurance, though this may soon become available to me. I was told by one doctor that I had scoliosis, but during that time I could not afford the many physical therapy sessions. I would like to talk to a doctor about possible pain relief medication in order to help with this issue, but I do not want to come off as some sort of junkie trying to score pills. Do you have any advice on how to go about this?
