Hi sept zen, sorry it is rough going. My glute problem turned out to be periformis muscle issue in that it was pressing on the sciatica nerve. It is a form of sciatica. I had a massage done by a therapist in a chiropractors office and she helped a lot. She stretched my leg too, the other thing is that I do are clamshells, side leg raises, glute bridges and stretches for the periformis in addition to the stretches she did. Lie on your back, extend leg straight up and then rotate it twoard the floor to the outside, this stretches the hip flexor The one I really like takes 2 people, and may not be right for you because of swelling and stiffness. If you think about it, in our early days, we spent a lot of time with our leg stretched out straight and sitting or lying down. Those muscles atrophied, I am sure. The stretch as I can best describe it, replicates the CPM machine. My husband pushes my heel to my chest while I am lying down and I hold for 1 minute. That stretches everything right down the middle of the backside. I am better now. My os nurse says some people have sciatia after surgery and if massage and stretching don't work, they can give you steroids. It can be tough to treat. Hope you can wean off meds, it is a shame you can't take something else. Last week, I was taking 1 to 3 Vicodin a day, not for the knee but for the pain in the but and slightly down the back of the leg. Yesterday and today I have had none. I have been active today doing housework and cooking for 5 hours so now time for a rest. I hope you can get some relief, the sciatica is worst, even more so than the knee.
