i went off accutane almost a year ago and those symptoms went away mostly about 2 months after i stopped taking it. When i used to relax my back when i laid in bed, it would hurt severly for a couple of seconds then stop, and sometimes, this long after ive stopped taking it, i'll lay down to sleep and relax my back and i'll feel that stitch of pain in my lower back, only like once every month or two though. But yea it goes away mostly
