@tennisgal, Bless you and I can so relate.

There were some PT exercises and the weighted board push was one that would cause so much pain for me. It would take me days to get back to normal. I told the physical therapist I could not do those anymore and she was ok with that and gave me others to do.

PT should not cause so much pain and swelling for you. I have other health issues that would flare up as well if they over did it in PT. I at times would take an entire week's break from PT and do exercises at home until I was able to go back to PT. I definitely would elevate and ice the knee and also talk to your doctor.

I know PT is not pleasant, but, it should not be torture and cause setbacks like what you are describing.

Praying for you. Blessings & Prayers.....
