I have a mild bulging disc (L5 S1). It happened last November and I am currently in much better shape than I was last year. I go to yoga and my flexibility has not improved much since my injury.
Before I was injured I could almost (one inch away) touch my toes, I know not great. Now I can't even bent at the waist to a horizontal position. My physical therapist said that I had very tight ham strings. Is there any possibility to regain greater flexibly or is my back scarred and I will have to accept limited flexibility?
