I have had a burning, hurting feeling underneath my breastbone for sometime. I can "feel" something there when I cough, sneeze, and at other times. I also seem to have a lot of gas (much burping and passing gas), and indigestion. I was diagnosed with diverticulosis about 10 years ago. I had an endoscopy and colonoscopy in July 2015 (3rd ones I have had in 10 years' time). Same diagnosis of diverticulosis. When I complained to my family doctor about the nausea, burning sensation, and burping, he ordered an ultrasound of my gall bladder and said it was normal. Sometimes I am so miserable! I feel nauseous but don't throw up. Any suggestions?
