Back in 2004, I had a Nissen Fundoplication done for GERD. Not quite a gastric bypass, but similar in some ways. I also have Fibro and at the time of the surgery, I wasn't using any pain medications beyond extra strength Tylenol.
After the first week of the surgery, my body started returning to 'normal". I had a lot of pain from the surgery but I didn't hurt more over all of my body - I actually felt lighter. This went on for a couple of weeks and for about 2 months, I had almost no pain at all when I bent down or stretched, and going up and down stairs was easier for me. The weight started to come off (I was 180lbs and I'm 5'2") and I remained relatively pain free.
I started doing AquaFit with a girlfriend, switched some meds around and started tracking notes in my food journal. After about 2 1/2 months, my Fibro pain became more pronounced and I started feeling pain more and more. After a fitful sleep, I woke up in my bed, stiff and sore, and it's been like that since.
You may very well get no relief at all...you may be lucky and get complete relief. I don't think there's any one thing that is the secret to not having surgery pain interfere with regular pain. Just remember to take things slowly, DON'T rush when eating (chew very carefully and swallow and you won't get a sensation of food being stuck), drink lots of water and when allowed, start doing some exercise. I have a Nintendo Wii at home which is great for exercise...plus I walk every evening for about 30 minutes.
I hope this info helps even a tiny bit. Good luck with whatever you decide...we're all here for you!
