Update on my hip flexor: doc thinks it might be a torn labrum and basically told me I'm SOL if that's the case. Said it would be time to move to "low impact" activities, although I'm only 29 and cycling is pretty darn low impact, so I wasn't real impressed with that. I'm getting an MRI in a couple of weeks and then we'll see -- if no tear, I'll go to PT, so here's hoping....
