Sounds like gall stones. Looks as if your situation is reversed from mine. I had gallstones 22 yrs ago and your pain indicators sound like mine did. I had the surgery (the full scale surgery) and was fine for a few days and then it started again. Apparently a large stone had been hiding in a bile duct during my original surgery. I had to go to another hospital for a special procedure (transoral) to go in an cut a muscle to allow the stone to pass. After that I was fine. In the last 10 years I have developed a hiatal hernia and acid reflux. (funny, I had none of this before being placed on cholesterol medications). The reflux is under control and there is no rhyme or reason as to when I have an episode. The hernia however is causing me lots of discomfort. At times my food gets stuck or slows down. Seems to take forever to make it to my stomach. This is so sporadic and there is no way to predict when it will happen. I have been talking to my Gent. Dr about the Esophyx. He has reservations about it and asked me to wait 6mths so he can get more information on results and success rate. Luckily I work in the hospital in FL where the Dr is experienced so it will be easy to have done.
Good Luck with your treatment, if it is gall stones it is fairly easy to resolve nowadays. The removal is much less invasive than it used to be.
I was curiouss to know if there are any persons out there who have had the esophyx procedure done by Dr Overcash? If so, I would appreciate any info or tips you could provide.
