I was just watching the live stream at SBE. Alex stopped by the commentator booth and asked the chat what to do about sciatica. One of the chatters recommended chiropractic.
At SBE there was a gal giving demos of a small muscle electrostimulator. My rotator cuff problems got so aggravated from remodeling work last week that I never even took my cue out of the case at SBE. I was in so much pain it hurt just standing there, never mind swinging a cue. I sat down and let her try it on my shoulder. Five minutes later the pain was gone. Of course, it was right back again today.
I was thinking it might be a temp fix for sciatica IF you know where to put it. It's pretty powerful stuff, and could exacerbate the situation if used incorrectly, but a good PT or sports physiologist would be the one to ask.
Good luck, sciatica pain sucks.
