If oral methylprednisonlone relieves my back pain is it likely that injections would help as well? 1. advanced l2-3 dd with diffuse endplate irregularities and prominent discogenic marrow edema. 2. moderate left facet arthropathy at l1-2?

I do think it's likely that epidural corticosteroid injections would be even more effective. However, if you can get good relief that lasts weeks,I'd be inclined to stay with medrol dospak but not more often than every three months. In this way you'll obviate the invasive treatments of epidural injections. As always, your personal MD, who knows your condition should give you his/her recommendation
