Hello, can anyone help me please?? I have had chronic breathing issues... went to the emergency room and the doctor gave me malox which gave me relief. He did complete blood tests, heart tests and oxygen level tests on me in which all of them came back perfect. I went to see a GI doc and he recommended nexium... I have been on it for ten days and I do feel a relief but not drastic... I still have breathing issues every time I eat something. It takes a long time to digest, I even drink organic ginger tea and eat greek yogurt with all the pro-biotics, but it still has not completely gone away. It feels like I am bloated with large amounts of gas and it stifles me. I changed my diet... i eat very little now and stopped eating choclate, caffeine foods and drinks, no alchohol, citrus foods and drinks... all of the no-acid foods. Please can someone tell me does Nexium take a while to work ? I have been on it ten days and the issue still persists...
