I read something when I was researching sciatica and pinched nerves. A chiropracter said that slight forward tilt really aggravates sciatica and pinched nerves. He mentioned the tilt you take to vacuum, to do the dishes at the sink and sitting at the computer really causes a lot of trouble. I think he is right.

I don't vacuum much. LOL I tell Hb it hurts my back and one leg. He just looks at me like I'm crazy. But it does.
