@scottjeffe In addition to pain, the xray showed tissue abnormality along the femur, elevated chromium and cobalt levels in my blood, and other indications of metal poisoning,
all pointing to a failing metal-on-metal implant.
This past autumn, 7 years post-revision, I had substantial hip and groin pain again. After confirmation by the ortho that the implant is solid, I was diagnosed with bursitis. For the past 2 months, I have been walking multiple times a day on level ground and doing stretches twice a day. Now the hip aches, but is tolerable. Due to digestive issues from other health issues, I am a no-NSAID person, so I use ice and topical pain rub to ease things. I may eventually have to consider steroid injections, but saving it for now.
