I have had alien pain prblem under my right
lower rib cage
for at least 8 or nine years. I first went to gastro doc. Had rib cage
pain, stomach pain and dyspepsia at that time. He did blood test, endoscope, colonoscopy, and ultrasound of all organs in stomach. Everything looked good. Gave me pills for dyspepsia. Returned several times over next couple of years with same type of problems. He said I had something going on, but it wasn't gastro.
