51 years old, post-menopausal woman with severe food allergies (rapid heartbeat, throat swelling, exhaustion for a week). I have had acid reflux most of my life which mostly resolved upon removal of certain foods from diet, but it has been acting up every night for the last few weeks. The last two days I have had pain between breasts when I swallow food, bouts of nausea, bouts of feeling dizzy, hot flashes, and a tightness with some shooting pains near my right ribcage (liver, gallbladder, stomach, small intestine?), and I have been feeling very exhausted. Concerned about possible ulcer or erosion of my esophagus or gallbladder issue, but this could be food allergy related. Any thoughts
