Update

Yesterday a letter came from the surgeon who put in my artificial hip four years ago- it seems the manufacturer is recalling the hip because they are falling apart before they've been in five years.  I think that's probably the explanation for the problem I'm having with my hip and leg.  So next week I see that surgeon and see what happens next.  I  can't imagine there's anything they can do about it except replace this one with another one.  At first I just laughed because it seemed so ridiculous.  Now I'm just going "What!!!!  I'm not a car that can be brought in for service.  I have to go through a long surgery with a long rehab.  GRRRRR!"  I will come to terms with this in a few days but right now I am outraged plus amazed.
