Zephyrcreek, my middle son had to swallow one of those camera capsules a couple years ago. He had been having some episodes and had lots of tests done. It took 4 years before they finally found out what was wrong. He would go up to a year between episodes and they could not do any testing unless he was activly bleeding. He had meckels diverticulium, something he was born with and it was corrected by surgery. he is fine now. I hope that they are able to find out what is wrong and that you will be feeling much better soon.
