Hello Doc,I have been having intermittent throbbing in my lower right abdomen from March of this year until the present.  I have had a barium swallow, ct scan, upper GI ultrasound, and colonoscopy completed, all of which had unremarkable results minus a small benign polyp and a stone in my kidney which the doctor is not worried about.Im concerned with this dull throbbing pain as I have been diagnosed with IBS, which I told my GP I am uncomfortable with that diagnosis.  I was put on Dicyclomine by the Gastroenterologist.I have had ARD since 2003 and was on ranitidine for years, had a scope done in 2007 which verified in which the doctor put me on omeprazole (and Ive been on that for years).  Im 27, 215lbs, 510.  I have also had carpul navicular surgery on my wrist where bone was grafted from my right hip (also has a burning sensation associated with the throbbing in the right hip.)  I have a varicocele removed from my left testicle in 2008.  I think thats all.
HI. Thanks for your query and an elucidated history. Since all the tests are normal you are a patient of IBS for sure. The proper treatment is as follows
