Jenna,
First of all good luck with your surgery I hope you will have the longest remission ever! All I can tell you is that everytime I visit my GI and I think I'm having the worst symptoms ever, when he assures me that everything is OK, I feel like a bird ready to fly! I think the pain and symptoms play games with our heads! I mean once I went to my GI's office feeling certain that I was having a blockage, and when he examined me, he thought I was crazy! He said my belly looked perfect, no noises, soft etc.... I don't know what's wrong!
Maybe you don't have symptoms because you know you are going to have the surgery and everything will be under control!
All the best,
Christina
