in August of 2005, I had a severe hamstring group tear, that was never addressed. The tear was about 2 inches above
knee, rear of thigh. Immediately after the injury, I had the sensation
of "sitting on
a lump". Lumpy area is high in rear right
thigh, going into groin area. I have been sitting on
this "mass" for all this time. 3 mri's, 1 ct scan, and 2 xrays. They can't see a thing, but I still have involuntary muscle spasms of the hamsting...
