Hello Dear, I would advice you not to put your sciatica pain into the shade of painkillers as this can lead to increase the problem in due course of time. I would advice you to get a thorough evaluation on what is the specific cause of your sciatic nerve pain and work on rectifying it rather on reducing only the pain. The various causes of sciatic nerve pain may be: Compression of nerve due to a disc slip, greater sciatic foramen calcification, piriformis muscle tightness, osteophyte compression, spinal canal stenosis, etc. Take a route towards complete health.
