Is this normal?

I am home now.  Had my scope done this afternoon and I was right...it wasn't in my head.  My opening was only down to 7mm but there was scar tissue around it.  That was where the food would sit and come back up.  They had to stretch my opening to 11mm now.  I hope I will be okay.  Thank you for your responses!

Cheryl, I'm glad they got you taken care of.  I think this is pretty normal and once you're all healed, it shouldn't happen again.
