I have sciatica--what can i do for it?

Mostly nonop: Time, rest, activity restriction, medication, physical rherapy, epidural steroid injections, chiropractic, guided exercise - some or most in combination with 90% resolving without surgery. Lifestyle changes may be needed in terms of weight control, exercise and not smoking.

Sciatica: Meds, exercise, physical therapy including mckenzie centralization techniques, traction, inversion table. Many things are used.

Pinched Nerve: Sounds like you have a pinched nerve in your back. I would suggest seeing a pain/spine specialist to evaluate you further to evaluate what level and what can be done to treat you. There are interventional treatments besides medications and surgeries that might reduce or eliminate the pain altogether.
