I thank you for all the good wishes,

they are very much appreciated.

The problem flared up again, badly enough I could barely walk.  Things were checked, and I was checked in.  Something new was tried which actually helped.  Hopefully that will remain helpful.

Know how you're supposed to get a followup with your regular doctor after you've been in the hospital?  I had an appointment with him this week that was set up a couple of months ago to followup on something unrelated.  This appointment is going to start with "Yes, 'X' is doing much better.  Now let me catch you up on the last couple of weeks."
