hillls,
I have actually never really had any pain. My quads(more left than right) get fatigued/deadened extremely quickly. You might equate the feeling to the feeling you get in your arms after you take a dumbell and lift it until you can lift it no more. My quads just get heavy and become visibly bloated. It is almost like the "swell" that weightlifters talk about.
I don't think that my problem is the labral tear in the traditional sense. I have a catching sensation now and again, but since I don't have any significant hip pain, I think the tear is working in another way.
Basically, the labrum acts as a seal on the hip joint. When you break that seal (tear the labrum), the hip becomes destabilized. Then, your hip muscles (flexors, adductors, etc.) become hyperactive in trying to stabilize your femur. In some way, I believe that this counteracts my proper running technique. But it isn't just in running. My legs feel dead when I bike, walk, or even use an ergometer. It's all tied to hip flexion in some way. I definitely don't have all the answers and neither do the doctors (otherwise I would be better by now!) but after a ton of experiments this is my best guess.
If you do have a labral tear, I would recommend seeing someone local first. If they think they can operate on it, then see Phillippon. He is supposedly the best, but only if he knows what wrong with you.
In response to hskid, I have tried a variety of regimens. I stuck with the regimen from the Speed Clinic at UVA for two months. It helped some, but was incredibly time consuming (1-2 hours per day) and didn't really fix anything. Since then I don't even bother with any other doctors who tell me I need to stretch and strengthen. The Speed Clinic has as good or better doctors for runnning than anywhere else. Therefore, I don't think this problem is just muscular. Something is going on at the skeletal level.
