I found out today from the MRI I had done last week that I have a bulge at S1/L5. I had a lamectomy and discetomy surgery done on that same disc last year, not once but twice. My question is, How can I have a bulge in that disc if I don't have any disc material left? I just don't understand how I can have this. Any insite would be appreciated. Oh, by the way, I'm scheduled to have steroid injections, a series of 3, done on that disc to reduce the bulge.
