I have to take deep breathes cause I feel like my lungs don't have enough air in them.My chest feels tight. It almost always seems worse after eating. I've had a normal EKG, normal CXR, pulse ox 98% roon air, normal Ct of chest,normal ct of abdomen, normal gallbladder us, HIDA scan with ejection fraction of 60% but did get abdominal cramping and some nasuea when had CCK ejection, Do have some constipaiton,but do have IBS. Main symptoms is just chest feels tight like not getting enough oxygen especially after eating. Could this still be from the gallbladder?
