Well, I got the results back of my MRI. Nothing for them to report other than some signs of arthritis. So it's looking more and more like Piriformis Syndrome.

As Baker says, "Pinched nerves in the back are the most frequent, but not the only, cause of sciatica. Occasionally, the nerve is pinched in a buttock muscle, the piriformis, rather than in the spine." This is why you must find out where the nerve is being pinched.
SadieKate, thanks for the links. I re-read the article at answers.com and it says, "Treatment for piriformis syndrome includes avoiding activities that aggravate the condition, such as running and bicycling." That's not too encouraging. My doc hasn't called me back for a follow-up so I guess he's done with me. Looks like this is just something I'm going to have to live with.
