First I want to find out what's wrong with it. And yes, I kinda expect surgery; I'd give it a 75% chance. I can feel things move inside the joint when I do crazy, wild things like walk or climb stairs or get up. What concerns ME is that we have tickets to fly to Dublin on May 18 and back on June 1. Fortunately, Pat took out trip insurance and she can always go without me (a couple of friends are also going.)
