I'm finding that the PT sessions are a workout of their own these days. At first the PT was simple little bends and easy moves, but they have been really putting me through it, to the point of me having to change clothes before going to work! Today they had me roll this tool against my ITB for just six minutes, using as much pressure as I could. Upper body workout! Then tough stretches where I have to maintain crouches, donkey kicks (lots) and a variety of creative and grueling ways to move up and down. An hour of this stuff, on top of a half hour of manual manipulation. Yet there hasn't been much swelling afterwards.
I'm going to try 20-25 minute walks and watch for the point when the swelling happens; that's a helpful metric, Dearjr.
