I’m 3 weeks, almost 4 weeks postoperative. I’ve been seeing this PT person for three visits. For extension, I’m at -5 and for flexion, I’m at 118. But he has been pretty tough. When he takes a measurement, he presses on my knee in flexion and extension. And he’s not gentle. He makes me scream out loud for him to stop. I feel he’s pushing me too hard. Any thoughts or opinions..??
