I can concur with the PT. I believe that the most traumatized I've been in my life while conscious was when the PT worked on my frozen shoulder beyond the limit I could bear. I barely managed to avoid passing out and breaking down in tears (didn't quite avoid that) for the next hour after I left her office. People must have wondered why I was hanging out in the parking lot for so long, but I was afraid to drive. On the bright side, though, my shoulder now works pretty well.
