I had mine removed last year. I never had a painful flare up, just this nagging ache in my side allllll the time. It went around to the back too and it was just a miserable feeling. I finally got it removed (after several years of denial) and it was instant relief. The surgery was nothing, literally. In and out in very little time. I was up and walking later that evening. The bad thing for me was the pain after. Every time they gave me a narcotic, my BP bottomed out. It was no fun going through the first several days with just Motrin, lemme tell ya. Other than that, it was easy.
Something nobody bothers to tell you, however, is about dumping syndrome (which I'm sure hubby knows being a nurse). And lemme tell you - it sucks. Greasy food, leafy veggies, fatty food - forget it. Instant dumping and run for the bathroom. I know this is going to sound like TMI, but I had several friends warn me ahead of time thank God, otherwise I would have thought something was wrong. He's going to have to figure out which foods trigger the DS in him. Once he does, trust me, he'll learn to plan accordingly. You've got about 10 minutes after you eat and that's it, then you better be near a bathroom.
The surgery? Piece of cake. The relief is wonderful. After? Until you figure out what works for you, not so easy.
