Sally,

They have me do a series of stretches to loosen the muscles up some. They seem to be adding a few new and extra stretches each time. Then they do manual manipulation of my shoulder and neck (think very deep tissue massage). Finally, they put me on a traction machine that alternately stretches and releases my neck for about 15 minutes.

It seems to be slowly working...the deeper they work in the manual manipulation portion, the better it seems to feel. Went to PT last night, then went out with a coworker and rode about 20 miles in 100F heat afterwards. My shoulder only hurts a little today, so maybe I am past the worst of it.
