Had one that I had surgery for:

I still had lingering on/off sciatica for a year, but found that PT and mobility exercises made the pain and discomfort mostly stay away. I still get some pain when sitting for long periods but not sure it's from a pinched nerve as a shifted pelvis or SI joint. MobilityWOD was a big help.
To this day I'm not sure if the surgery was the fix but after more than a year of constant sciatica down into my calf I was willing to give it a try.
