I have chronic SI joint dysfunction due to a cycling accident that fractured my pelvis in 2005. Unfortunately, cycling has the opposite effect on my pain as it does on staceysue's. Usually about 45-60 minutes into a ride, my right upper buttock and hip area starts aching, and the pain radiates down into my thigh. Getting off the bike and stretching helps for awhile, but inevitably the pain comes back, and I have to stop and stretch again. It doesn't keep me from cycling but is definitely annoying and has limited the distances I am willing to ride since my accident.
I have been to a couple of different docs and PTs with no real improvements yet, and the pain actually seems to be getting worse lately -- perhaps because of my various other activities too -- long hilly walks, jogging, weight training, pilates, or maybe just because I am getting older. I may have developed arthritis in the joint, which was a possible side effect of my injury and surgery.
From the reading I've done, there are different forms of SI joint dysfunction as the joint may be too tight/frozen or too lax, and it's possible that this may account for the difference in my experience vs. staceysue's. I honestly don't know exactly what the exact nature of my problem is (too tight, too loose, etc.)
