I had a pretty much constant pain in my replacement hip joint. I had been told by another provider that it would most likely take a major surgery to get any possible relief. I went to Dr. Hansen, and he told me that it didn't appear to be in the joint itself, and he suspected it was a muscle, or tendon problem. Turns out that was the case, and after an injection to the hip bursa, I am now pain-free, hiking, etc. What a good feeling.
