Dear friend,
If you are in unbearable pain in hip and/or knee and they are SURE it is an arthritic joint, then consider joint replacement. If pain is on your right side only correcting one joint may fix the other one also.
I understand your fear. It is very scary. After wits end with arthritic pain I had both knees replaced 6 months ago to the day.
Results? Well, no more arthritis pain and can certainly stand and walk for much longer than before. But the healing takes a loooong time. My knees are still very stiff, my balance is not great, and won’t be going on any hikes. I’ve been told now it takes a year. Was it worth it? The jury is out on that still. It’s a horrible operation and last resort imho. So, take joint replacement under serious consideration. It is not easy. It hurts a lot. Good luck you and blessings.
