I am 65. I was diagnosed with pinched sciatic nerve on right side. I have a screw from a lumbar fusion in2004 that has come undone. I will have surgery done next month. I am taking flexibility, 800 ibuprofen, norco and I start on steroid pack tomorrow. My question is my ankle and foot are swollen. Is that something to aware of? I have put ice on it. But it was numb and hurt from nerve. Now this has happened. I was a little concerned, also will the steroids have the swelling. My doctor usually swelling is not associated with it.
