Bloating, morning dull pain in abdomen, with headache. Yes headache and confusion associated with these symptoms is unusual. I have changed bowel movements, eating small portions see any changes. My hunger level is fine. But a general feeling of pressure up to throat from chest and headache makes me crazy. Is it something can be diagnosed with endoscopy ? what about lever, spleen, pancrease, gallbladder.. etc.. Could you please point some specific could be there.
