Hello Jrice,
Welcome to MedHelp's Pain Management Forum. I am glad that you found us but very sorry you are experiencing chronic pain. I hear the frustration in your words. My heart goes out to you.
I know your concern. Sometimes when test do not produce an obvious answer the medical providers seem to lump like symptoms into an IBS diagnosis. They can be correct as not everyone has the exact symptoms but they can also be in error.
Another thought might be adhesions from your surgery.....even if it was a scope. That would not account for the right sided under rib pain. Adhesions can be very painful and cause similar symptoms mimicking endometriosis.
Have you sought a second opinion....or a third? A second pair of eyes can make a difference. Consulting a physician connected with a large teaching facility or a well known national clinic may be beneficial. Have you seen a good Gastroenterologist?
While you are always welcome here we have other forums that may provide additional suggestions or information.
You might also want to post on our Gastroenterology Forum. Here's the link:

"Abdominal Pain" reasons can be very difficult to accurately diagnosis. It will take some time and patience. I encourage you to seek another opinion. You may have IBS or you may not. I do think you may feel better if you had a bit more searching done into your symptoms. It's important that we trust our physicians. You don't sound like you have that trust....and that's perfectly okay. In my opinion it is important that you find a physician that you find trustworthy and you can develop some rapport. Someone that will take a lot of time and explain in detail their thoughts and diagnosis. I know it has made a huge difference for me.
I wish you the very best and hope that you will be active in our community. Please feel free to ask additional questions or just vent. We are here to offer our support. I'll look forward to hearing from you again soon.
Take Care,
