I went to physical therapist after twisting my right knee. He poked around on my side hips and asked if they were sore. I ,surprised, said yes, it hurts most at night and wakes me up if I am sleeping on my left side and when I walk a lot. He added some exercises for my hip. It worked!!! I asked if the other physical therapists there knew about the exercises for the hip. I was ready to bow to him. He said they did know. Hallelujah !!! Knee AND hip were fixed!
