The patients will be followed during each block and over a period of 1, 3, 6 and 12 months and on each follow-up visit will complete computerized set of questionnaires as they did before the procedure. The patients charts will be then reviewed for one year after the initial procedure to determine if further epidural steroid injections or surgery for the presenting problem were required. It is anticipated that the appropriate number of patients will be enrolled within six months of study initiation.
