I have a disc herniation at L5-s1 and L4-L5 both touching the thecal sac. No nerve Impingement If my pain is on the left it goes down my leg, its neurological and I can sometimes control this will self talk sometimes it vanishes away if I read the book or listen to any mind related videos. Three weeks into TMS journey, I have improved a lot. When I sleep on my right total pain shifts to right easing 100% on left.. and the pain is exactly at the position I mentioned in the pic below (in black color). The pain is Muscular & It is nearly impossible for me to sleep with out screaming aloud while I turn to left or right in bed. This pain doesn't go down the leg if the pain is in right. I am confused what is the this pain on my right. When this pain comes I completely forget about TMS as it bothers me so much. Based on posture in bed this pain will completely shift to left tonight or in coming days.I didnt note what activities moves this pain to Left. Sorry We as TMS'ers shouldn't think structural but I have to post this to understand this. I dont have access to TMS therapist. This is how my MRI stands - central disc protrusion at L4/L5 WITH indentation over the thecal sac. Disc bulge at L5/S1 with indentation over the Thecal sac.
