Wow, That is tough. You go through the hip replacement surgery and it doesn’t completely live up to what you expected.
My right hip replacement in 2016 was completely successful. I didn’t even think about my hip after that. It was bone on bone also, but I was able to walk without assistance before the surgery. I was also 8 years younger.
This left side has the ravages of arthritis and the pain even with a walker is horrible.
I hope you find a physical therapist or a consult to help you.
