We looked over my right hip X-ray from three weeks ago, my left hip X-ray from 2017, and my left knee X-ray from earlier. My left hip is in worse shape than my right, and Dr. Re thinks I might need both hips replaced. So, I asked, why is my right hip causing me problems if the left is worse? The answer: it's not the arthritis, I've got bursitis in my right hip.
