Did you mention the throbbing in your leg to anyone? Is it still throbbing? With forced inactivity because of your back pain, I'm concerned about blood clots.
I read "The Pain Chronicles" and it sounds like a lot of time, PT is still guesswork. Don't feel guilty about taking charge of your health and saying "no" if you think it is wrong. I strained my lower back recently and the OMM treatments have either not helped or made it worse. (I think I'm the one who made it worse, trying to do different activities thinking that would make it better, but that coincides with the treatments so I am not sure!)
