From what I read it's a 3 month old issue, am I right? If the pain has stayed centralized in the spine, that's great news, the opposite being, radiating pain into the gluteal region and leg, not so good.
Have to disagree with Kel (sorry, no offense intended) get an MRI for a more definitive diagnosis.
I'm assuming you all saw the Ronnie Coleman thread, not pretty.
Bottom line - it ain't fvcked till it's fvcked, it ain't fvcked yet, so get it properly diagnosed.
