Did you have a knee replacement or injury? I have heard knee replacements are much more complicated than hips.Hope your knee is good now! Biting down on a ball during ROM exercises sounds like your PT was rough!!
I am doing well.Hip replacements make all the muscles weak in the hip area. At first the leg is so weak cannot lift it much. I have made tremendous progress in just a week. The only "complaint" is lots of nerve pain, which I hope goes away. Every day brings more progress, yay!
I hope you are ok and are holding your own.Take care~
