Seventy-eight study participants will be randomized via a computerized randomization system using SPSS software in groups of 6 at each institution by a research nurse not involved in patient care. There will be 26 patients in each of the 3 groups. A physician unaware of the patient's treatment group will place 22-gauge needles in the relevant foramen under fluoroscopic guidance as determined by patient's symptoms and MRI findings. Once correct placement is confirmed by contrast injection, the blinded physician will leave the room and another physician will inject the medication. In group I, this will be 60 mg of depo-methylprednisolone. In group II, this will be 4 mg of etanercept reconstituted in 2 ml of sterile water. In group III, this will be normal saline.
