Not the OP, but I also had sciatica as a teen. In my case, it was caused by a chair whose seat was not level; it tilted slightly to the side. It went on for a year or two, I think. Eventually I realized what the cause was, got rid of the chair, and the pain gradually got better until it went away completely.
