I had a simultaneous BTKR in 2015 and a LTHR in 2016 with the right probably to be needed in 2017-2018. After experiencing pain in my lower back, thigh and calf, I visited my OS and said it might be time for my RTHR. He had xrays done and said that while I would still need the right hip done in the next year or two, I needed back surgery done in the next 6 months and probably a right shoulder replacement but I should try to put that off as long as possible. He knew I was moving away so he has no reason to push unnecessary surgeries. But holy smokes! I'm soon going to be fully bionic! How could these new joint/disc disintegrations be occurring so rapidly? Now I'll need to find an OS at my new home who does back surgery and one who does hips. And surgeons who I can trust as I did my previous one. My friend who is a nurse suggested that I be tested for lupus because of so many joints going bad. Anyone else have so many joints needing replacement?
