Oh!

You deleted! I'm sorry. I know your stomach troubles have got to be fairly stressful - they were for me when I was in the grip of them. The biopsies they do with scopes are painless (apparently, despite all the pain our guts cause us, THEY don't feel anything

). You will do just fine. Have you had the scopes before? The worst part, by far, is the prep. It's a new kind of torture. Hang in there! I hope they find answers for you. They didn't really find anything for me except unexplained gastritis. And benign polyps, and GERD up the wazoo. But I've been treating it for years, so...who can say?
Take care,
Moll
