Don't just call your OS. Call and schedule an appointment. Isn't there normally a six weeks post op exam? Call and schedule that appointment!
Ok, you read it correctly- initial recovery takes months and complete recovery takes a year or more. PT is saying stupid, uninformed nonsense to get in your head and frighten you. So, good job- you skipped one session. Why not skip all sessions for the next couple weeks and see how it goes? Looking back through your thread I see that you've been advised repeatedly to suspend PT and instead concentrate on rest, ice, elevation, and activities of daily living. You should be about done with home PT anyway. I suggest you call the home health company that sends the physical therapist and tell them you are suspending (or terminating) their services. Write a letter saying the same thing. They may argue -remember, they make $$$ from your sessions- but firmly tell them, "do not send PT to my home". If a therapist shows up at your porch do not open the door! You have the absolute legal right to refuse any and all medical services, which includes PT.
I didn't begin PT until 6 weeks after my RTKR. I recovered just fine, and my recovery has taken about as long as anyone else's. I had lots of discomfort for the first 12 weeks, with gradual improvement after that; in other words a very typical recovery.
