I have not experienced sore but have experienced dry mouth and dehydration. It is not a fun experience but always drink liquids! When was your surgery?
The problems i am having now relate to the exit of the pouch narrowing. I have had 4 scopes with dilitations - those aren't fun but it is better than having pain when eating. The first time the exit became as small as the circumferance of a pencil and i could not keep anything down
. Now things are getting better!
