Keep in mind that if the symptoms are being caused by nerve root impingement (usually a disc, sometimes a bone spur) that surgery will fix the mechanical problem but no surgeon will guarantee a relief of pain. Spinal stenosis is hard to fix and operating can cause scar tissue that worsens the problem! If the sciatic nerve is being entrapped somewhere in the hip instead, that's the area that needs repair, of course.

Not only that, in the long run (10-15 years or more) the outcome measured in mobility and pain level is about the same for people who had disc surgery vs. those who did not. Individual cases vary, naturally, and no one intervention from epidural steroid injections, electrical stimulation, physical therapy (or even a chiropractor if it works), and surgery are 100% effective.

I do wish you the best possible outcome though!
