I too, have severe bloating. I look pregnant. I don't eat much but have gained 25 pounds in the last year since my surgery and trust me, I don't eat much. I don't know what a globus sensation is. I am sorry for all you have gone through.
I too, thought maybe i had a gluten problem, but no. and no IBS, no Chron's Disease. I do hope we get some other replies because I am very concerned and I need to do something. I can't keep living this way.
I imagine you feel the same.
