@bushy first, I want to say, on anything like that you need to check with your doctor, or perhaps your PT place has a portal or is open for questions. I think the doctor is the best source though. We are all different, and different doctors have different preferences.
That being said, i believe I was told I could do what I could tolerate. My doctor did not want painful PT, he is adamant about that, and he is a very highly regarded orthopedist with an impressive success record.
As @johnbishop suggested, is your doctor at a hospital where you can send him a message on the portal? I prefer that form of communication to phone calls because when you call the doctor hears what the person who answers these calls tells him, whereas if the message is on the portal he gets the complete message.
I will be interested in hearing what your doctor says. I expect if it’s not causing pain, either when you do it, or afterward, he will say it’s fine.
