Hi @johnbishop. Thank you so much for taking your time to respond to my question. I appreciate it very much. I actually am currently in PT. And the PT had mentioned it to me. They are helping me keep flexibility, strength and mobility, and have been so helpful. I actually go in today to receive my hyaluronic acid injection, so I guess I will have a more clear idea of if it will help in about 30 to 45 days. Fingers crossed. I have lost 5 pounds in the past couple weeks and have 30 more to go, and that too will give me a more clear idea of how long I can wait before surgery. You have been so helpful. Thank you again!!
