My best advice to you is to continue seeing other doctors/gastroenterologists until you find out what's wrong! It's hard to keep getting the same answer over and over but you need an answer! I've been in a similar situation personally and was told for 5 years that nothing was wrong with me...it was all "in my head" until one day I found a doctor who knew what he was doing and was willing to truly find out what was going on! The problem has now been corrected and my life and work and family life are all reaping the benefits of a healthy, happy me! It would be helpful to obtain a copy of his records from each doctor he sees to take to the next one too. This will save time and testing and money. It's unfortunate these days with the technology we have that it's hard to find a doctor that has a desire to find out what's wrong and is capable of doing so! Good luck!!!
