Good evening @flaredhead, I see that @sueinmn has presented you with some important responses to your post. I just wanted to note one comment of yours and that is you are using heat for pain relief after therapy. I have had two TKR surgeries and I was strongly reminded to use ice as needed for pain. You can get special forms for knees that can be kept in the freezer so they are ready when you need them. I think Amazon has numerous options. I also like Vive health. http://www.vivehealth.com.

Please try some ice and let me know how it works for you. You can also use a wedge to elevate your knee. And every morning during my simple stretch Yoga, I do "Legs up the wall". You can find that Yoga pose online. It certainly helps me.

May you be safe, protected, and free of inner and outer harm.
