Most of the time the injections work better near the spine because that is where the actual cause of the pain is, irritation or inflamation of the nerve roots, but you rarely actually feel the pain at that spot, you usually feel the pain some where down the path way of that nerve. Like epidurals they inject the steroid to reduce the inflamation that occurs where the nerve root is injured. It blocks the inflamation process, and thus reduced inflamation, which reduces the swelling, and thus reduces the pressure on the nerve and thus less pain! That is why allot of times the surgeons often use the epidural injections as a diagnostic tool, if the injection reduces the pain, then that indicates that is the spot or the nerve that is bad, and thus that is the place that needs the surgery done. as in diskectomy or laminectomy or what ever.
It is to bad that more Doctors ( especially Pain Doctors) are not more aware on the proper procedures of weaning a patient down to a lower dosage of pain med. Or even completely off of them! Most are aware of doing it with prednisone, or other steroids, but not with pain meds! Unfortunately the patient is the one that suffers!
