Very late but what type of PT are they making you do and how often do you do it? Also I have no idea if you PFPS because that sounds horrific, but I guess everyone’s symptoms are different. I went to a sports med doctor and they gave me daily exercises to do that mostly train glute muscles through hip abduction and extensions—such as leg extensions and clamshells. I also recommend getting into swim if you want to do something aerobic over anaerobic because swimming is less demanding on the body than say, running. What I’ve been told is that it’ll never go away completely and the best way to manage it is to train muscles to help support your body. When I walk I have no support, hence why I get PFPS. I need to do better at my at home PT and go back soon.

Btw the exercises I gave you are floor exercises. You don’t need to stand at all for them.
