So I just got out of the er last night for severe upper abdominal pains. They did full blood work, urine test, and a ct scan of my upper abdomen. The pain has greatly reduced since last night still a bit sore but no cramps. After reviewing my test from the er my dr wanted me to do another test it's some find of upper gi thing were I gotta drink something? What kind of test is this? And now freaking out cause what did he see that makes him eat to do another test? Very nervous
