I have had chronic back problems for a decade. I had surgery to address stenosis problem a couple of years ago. I have had several procedures of shots and nerve cauterization by pain neurologist. This past April I had fusion of L4-L5. Pain continues in lower back with left buttock more severe but pain also in hips. Latest CT, not read yet by orthopedist who did the fusion says, At L5-S1, degenerative disc space narrowing is seen with moderate right but severed left L5 foraminal steosis secondary to loss of disc space height and disc bulging. No signigicant central spinal stenosis. Any observations on such limited info?
