Hi buffalo ~
the narrowing of the spine is called spinal stenosis. Thinking about surgery now may be to soon depending on what doctor's you have seen for this, what tests you had, and which less invasive treatments you have had so far? Was your first surgery on your lumbar spine? What kind of doctor did you see for your back pain? What tests have you had done? You said you doctor said you have narrowing of the spine, did you have a x-ray or mri?
The indent might be one of these spondylolisthesis, spondylolysis (see below) or something else.
Spondylolisthesis
a defect in the construct of bone between the superior and inferior facets with varying degrees of displacement so the vertebra with the defect and the spine above that vertebra are displaced forward in relationship to the vertebrae below. It is usually due to a developmental defect or the result of a fracture.
Spondylolysis
displacement of one vertebrae over another with fracture of a posterior portion of the vertebra. A defect in the neural arch between the superior and inferior facets of vertebrae without separation at the defect and therefore no displacement of the vertebrae. It may be unilateral or bilateral and is usually due to a developmental defect but may be secondary to a fracture.
The pain you have running down your leg's and it start's from butt cheek's even when I cough or sneeze it shoot's right down your leg's is called sciatica.
Sciatica
a lay term indicating pain along the course of a sciatic nerve, especially noted in the back of the thigh and below the knee. Pain radiating down the sciatic nerve into the posterior thigh and leg; can be caused by irritation of a nerve anywhere from the back to the thigh.
Please ask anything you would like to know about your back problem. I have information on just about all there is for spine problems, including kinds of tests, types of procedures, types of surgeries, types of diagnostic procedures, and so much more to share. ;)
