Ok, I went to the MD and spent about 1 hour with him. First, the Piriformis thing. His take is that its not just that muscle. He worked that right side in the buttocks region and pressed the area, then releasing the pressure and some shaking of that area. Seems like trying to undo the tightness. Its several muscles and I think he was loosening them up by pressure. And yes, it hurt, sharp pain. But I didn't cry.

Now, two days off the bike and no hammering.

I never did go to physical therapy or massage therapy. But I think what I got was like it, only maybe the MD was more experienced. Not too many MD's would do this. Didn't want to say this, but the MD would prescribe physical therapy and maybe some pain medicine to relieve the symptoms.
