@popolopo : have suffered from bouts of Sciatica for 10 years now. Started gradually, intermittently, the became worse over time. One leg at first, then the other one joined in. Had 2 guided injections (Oct. 16, May 17). They did help with the acute flare-up. However, best advice I can give you is to stick with the back exercises, and I’m sure the doctor also added core strengthening exercises. I do those daily (well, about 350 days/year), and I am mostly pain free. Perhaps take a session from a good physical therapist who specializes in back problems, and if you are open-minded, perhaps some acupuncture.
I had tried chiropractic when the pain first started, but that did not work at all. Sports massages did help, but only temporary. Sorry I can’t wave a magic wand and make your pain go away....
