I can't really read your MRI because I am not a doctor. But I can read between the lines. If he gave you pain meds and told you to come back if it gets worse then do just that. Take your pain meds and go back to him if it gets worse just like he said. I've seen your type of MRI results alot on another forum. If he didn't mention surgery then he doesn't believe at this point that surgery would be very helpful for you condition. But he wants to see if you improve or if it worsens. Did he give you any restrictions like not lifting anything heavy? Or any exercises to try or not try? You could ask him at your next visit.
