I've been rehabbing a back injury that I incurred while working this past June. I never got an MRI or official diagnosis of what my injury was, but judging by the symptoms, my best guess was a mild to moderate L5-S1 disc injury.
While I have no more nerve pinching symptoms, I find that what still remains is a pain in my sacrum. The injury is somewhat sensitive to touch, especially in the area just above the glute origin, moreso on the left side. (Here's a visual: http://upload.wikimedia.org/wikipedia/commons/e/e7/Gray96.png )
I find that I also frequently experience painful and "tight" sensations between my sacrum and coccyx, which occur mostly after prolonged sitting.
Any clues of what might be wrong, and how I could best resolve the issue?
