I have just gotten over this, but am still looking over my shoulder hoping that it will not return. One of the worst injuries I have had to deal with so far. There is just no way to immobilize it so it drags on and on. I initially injured it pushing hard (racing) alongside one of my roadie friends in an over-agressive position on my road bike down in the clip on aerobars. I could feel a burn in the high hamstring/glute area. The next day running it became very apparent I had a problem. I dropped my saddle height and road quite a bit last summer, as it did not seem to hurt as much cycling as running. It t really hurt when I ran, particularly during the swing phase of my stride. After about 10 months, I did get a couple of cortisone shots to the bursa (needle guided by some imaging device) and then took almost 3 months off. That seems to have done th etrick. I just did not want it to mess up another summer. Best wishes on your recovery
