I seem to get sciatic nerve problems when I am prepping for our major out of town fishing trips. Mainly from moving big tackle bags and coolers by myself. Then sitting in the vehicle on a 12 hour drive seems to result in me barely being able to walk by the time we get to our destination. Unfortunately I'm the boat captain for the trip and the other guys are pretty lost if I don't go along, so laying out a day isn't an option. So I had to figure out a way to somewhat manage the issue so I can function.

I found the sciatic nerve pain didn't really have as much to do with my back as it did with extreme tightness in my hamstring. I know it sounds weird but if you talk to therapist they can confirm this. I got a stertching bnad so I can lay on the floor and loop the band over my foot and pull my leg up and get a really long and slowly progressing hamstring stretch. Then I ice my lower back after stretching and as soon as I get back in from fishing. The combination of stretching and ice seems to help more than any muscle relaxer or pain pill. May be worth a try.
