Did your sciatica go away on its own or did you introduce some new exercises to your routine? I've had some pain in my left leg for a few months now that is likely sciatica. I did go to the doctor, but it wasn't a particularly helpful visit.

I did physical therapy which mostly involved strengthening core muscles - if the cause is a herniated disc, which it usually is, this can slightly speed up the recovery process because a stronger core can push the disc back into place. But this is a speedup in the sense of "8-10 months instead of 10-12". Welcome, certainly, but not a silver bullet.

The other thing the PT taught me was nerve glides (also called nerve flosses). These don't seem to make recovery any faster, but help a decent amount with pain and tightness .

Sadly, that plus loading up on NSAIDs appears to be about all you can do for most cases of sciatica. I got a consult with a back surgeon who basically said, "I can operate if you want, but it probably won't help much, you just have to wait".

Good luck: it can be a pretty miserable time, but the good news is that most cases of sciatica do in fact clear up on their own even without PT. It can just take a while and you'll be hurting in the meantime.
