hi,i am a 51 year old male ,and for the last 4 months I have experienced pain in the upper right abdomen.when I wake up I fill fine , but as the day goes on and I am active , it radiates to my stomach . I have had ultra sound , ct scan of abdomen , and chest . colonoscopy , endoscopy , hydascan , blood work , and nothing has showed anything abnormal . Doctor now is sending me to have physical therapy for my back . Any ideas ? I do drink beer .
