Burning,I have worked on these boards for 3 years and had the surgery myself 3 years ago. I can tell you that what you are describing is not a bit normal.
People will have some discomfort, but the amount of pain you're having is not right. You should definitely insist on being seen right away.
There's no way you should be in that much pain. Be sure to be forceful regarding what you're dealing with and don't take no for an answer. Tell them they need to fit you in. Let them help you get to the bottom of what's going on.
It may be spasms, in which case they should be able to treat you.
Here's a Mayo Clinic link:

That may not be what's going on, but it does come to mind.
Here's hoping you get in to see your GI doc or surgeon soon.
Hang in there. Things will get better!
Take care,
Denise
