I have had the exact same symptoms as you and about 1 1/2 years ago I was officially diagnosed with celiacs disease which means you are allergic to gluten (wheat, flour, malt, etc). Get tested with an ERCP to verify if this is what it is.
Thanks

Lower right quadrant pain can be due to inflammatory bowel disease, like Crohn's disease, diseases of the appendix, irritable bowel syndrome, or non-GI conditions like referred pain from a hernia or kidney.
I would advise a colonoscopy, which can exclude colon cancer. Small bowel studies can also be considered with a small bowel follow-through.
If appendicitis is suspected, a CT scan would need to be performed.
If the tests remain negative, irritable bowel syndrome can be considered, and treated with antispasmodic agents or increasing the amount of fiber in the diet.
