Admittedly, I have emotional problems with authority figures, so physical therapy with a person telling me I need to do something painful would just make me shut down, and I'd probably walk out too. But if I decide to do the same thing myself, alone or with a neutral non-commenting person like my wife, I can handle the pain much better.
I agree with those who've asked, what solution are you looking for? Do you think the PT exercises would be useful to gradually increase strength and mobility, even if they were cut back a little when the pain is worst? Could you do them better as home exercises and handle a little of the pain, without the PT environment?
My one brief encounter with PT was when my oncologist referred me while I was hospitalized, because he didn't want me to lose muscle strength or lung capacity due to not moving because of pain. He didn't know I'd been forcing myself for the last several weeks to walk a mile on a hilly country road morning and evening, regardless of the pain in my side. With my wife and the dog along, it was "fun"--sort of, as much as anything that painful could be
--but if I'd had to do it on a treadmill with a physical therapist monitoring my speed and progress, no way. I would have walked--er, hobbled--out too.
The physical therapist had me walk the hospital hall with her at a brisk pace, which was actually easier than the hilly road, and immediately afterward she said I was doing fine and there was no need for any therapy--just keep doing what I was doing.
So it's maybe possible in some cases for a dedicated person to do PT-type exercises at home, if that works better psychologically. (Speaking mainly about
myself--don't know enough about
specific exercises recommended by PT's for other problems.) But of course that still means doing them regularly and being convinced they're the solution in the long run, and probably still suffering some pain, or at least pushing right up to the point of pain and trying to increase over time.
