My mother has been doing Tai Chi which has eased some of her pain, and I do Yoga and go to a chiropractor referred by my physician, which has helped with range of motion and pain management a lot. NSAIDS (aspirin, ibuprofen, naproxen sodium) help when the inflammation gets bad. I have heard that eliminating the deadly nightshade family of plants also helps, but I just can’t do that myself because I love my tomatoes and peppers and potatoes too much. I wish for him some comfort. It sucks to creak and be infirm.
