I am so glad I stumbled upon this site...now I know I'm not alone in my back pain!! I took Accutane 7 years ago, I was 18, and I STILL have HORRIBLE back pain. It's like something is ripping it apart from the inside. I almost scream when I lay down in bed at night, because laying flat is worse than anything else. I have seen doctors, gotten xrays, and I was so stumped as to why it was hurting, then my mom mentioned that it was probably from Accutane, so I decided to research it.
