Welcome to Mayo Connect. I had really bad pain before I knew it was my hips (docs had always blamed my back) so I rode a bicycle. When I couldn't manage that anymore, I switched to a stationary bike or walking in the pool. I feel they kept my quads strong and that helped with recovery.
Are any of those possible for you?

PS I was also eating NSAIDS like candy - that I do not recommend. It took my stomach years to recover.
