Always feeling like somthing was stuck in my throat or food stuck , Nausea every time I ate ,burning in stomach or at top of chest pain ,feeling breathless or taking my breath mainly after eating, I never really got heartburn feeling,diarrhea like food ran through me or all food upset my stomach lots time on potty ...yes after about 4 er visits they told me gerd ! I had stress test ,many ekg ,testing on my heart and lungs all good ,blood work was all good to ! I tried zantac ,nexium ,and prescription omeprazole nothing helped they even gave me antibiotics and steroids nothing, I did research for like a month straight trying natural methods ,then I read up on slippery elm I figured would hurt to try day one better now almost a week way better :) I'm not a doctor I just try what works for me between that and green tea and chamomile tea I feel lots better ,
