Hi Loz,
I'm surprised I missed your thread before, as I'm supposed to have a revision soon and watch for revision threads. Reading about how you were thought to have a loose stem, then didn't has me more than a little concerned. Did they ever mention anything about how much space you had between your stem and femur? I may be grasping at straws - Jo has already checked my images and said I was loose, along with my Orthopod.
And with all the talk of Bursitis, I had my pain management Dr. check, and I have a bad case. Like Jo said, they can do injections. Last resort is to surgically remove the bursa - which I've read can be done without negative consequences. Resting and topical Voltran gel is helping some, but it's only been a few days.
I'm glad we're talking about Bursitis more in the forum. I don't know why it's escaped my Dr's and PT, except medical people don't seem to touch or visually check you after awhile, unless you bring something to their attention.
Good luck and take it easy. I'd love to be able to walk over 1/2 mile, so your thread gives me hope, even though you still get overuse injuries. Continued groin pain can be related to a Psoas impingement, so even if your Dr. cut away tissue, it doesn't mean the Psoas can't become impinged, although a smaller cup reduces that chance. Pain that comes and goes is usually overuse - continuous can mean something needs more looking in to.
Best,
TH
