Diclofenac
"I was prescribed 50mg twice a day. I felt really good after 2 days. Went back to spin class (lightly) and light cycling. Then I felt good and did an elliptical. My Dr never told me to refrain from working out. After 26 years it's a hard habit to break. So I am in week 3. If I stand too long Sciatica returns. Some walks are good. He is doing this for 3 months. I hope it helps. I don't want cortisone injections."
