I suffered from sciatica and lumbago for about two years. My first doc sent me to a chiropractor who did something to loosen tissue in my low back. after a few months, I had no relief. I went to a different doc who prescribed physical therapy. The PT did the trick. Strengthening the abdominals was the key. Now I make it a priority to get out and walk briskly for a couple of hours at a time, several days a week. If my wife notices I'm limping, that's a big warning sign I'm slacking off on the walking.
