Thank you for the advice, Mona and MountainWoman.
Unfortunately, I kinda' got out of the loop with the surgeon (a very nice lady) but I'm not fond of doctors and somewhere in there I saw some late-night, lawyer commercials about metal on metal implants. So I never went back when I should have. [...WHAT... do I have to go back and get sliced open so they can replace it....] It's starting to "bite" me now. {...didn't have much choice at the time regarding replacment, but I never really thought what would happen if they recalled a fake body-part.)
My husband is really starting to worry me; if he anticipates that I might want something, he does it. I am trying to be responsible and sure hope he doesn't come home with more animals (plus I'm trying to stave off the matter of breeding which I thought was already settled.) Tonight I wrested a promise from him that we would find a stable (somewhere, anywhere) and try to see if I could ride. And he agreed he would ride too. ...SIGH.
