Ive Been Throwing Up At Night For 3 Mths. Ive

ive been throwing up at night for 3 mths. ive had the scope. gallbladder ultrasound, and Hida scan all normal except durning the hida scan i had pain in by belly that lasted into the next day. The gerontologist referred me to a surgeon. Had consult today after reviewing the test results and examination he did schedule me to have gallbladder out but said he did not think that my gallbladder was the problem. I can not connect any food to the attacks and it is always about 6 hrs after last meal that i throw up. The throwing up last for hours and i bust blood vessels in face and neck.
