Just admit you like "watersports," Brian. We're not judging.

I'm commenting to say there are a lot of good videos to help with sciatica. I find these guys good but there are many others:

Sciatica has a LOT of different causes, and what is called sciatica is not necessarily sciatica.

My "sciatica-like" pain turned out to be from childhood back issues caused (most likely) by carrying heavy newspapers in a bag on one side of my body six days a week for six years.

I started doing daily dead hangs, mobility and back exercises. I got rid of my pain in about six months and (touch wood) it has not returned in over five years. Good luck to your wife!
