Hi- I had my right knee replaced six weeks ago. I also iced my knee regularly, did PT exercises at least twice a day at home and went to PT 3x week. I’m at 130 ROM and 2 degrees flex; HOWEVER, my right side lumbar area of my back is killing me and my right gluteus hurts periodically. I did have L3-4 surgery in 2018 but that pain went away after the surgery. Now it is worse than ever. My PT is mainly working on stretches and exercises for my core and back rather than my knee since it is better. I’m so disappointed that one problem turned into a worse problem. My knee surgeon took an x-ray of my back and said there is more degeneration than in 2018. I’m afraid I may need more surgery on my back, but I don’t want to rush into anything if this is “normal” after knee surgery and may go away. Has anyone else had this experience and did the pain gradually go away?
