Hello, I have recently started taking Nexium per doctors orders. I have not had indigestion but have had sharp pains in my heart. My doctor did an EKG which was normal & decided the pains must be acid reflux. Since I started taking Nexium, 4 days ago, my bowel movements have improved & I have not had the sharp pains in my heart. But last night, I was awakened by the most horrible stuff in my throat. I ran to the bathroom to vomit & the stuff in my throat was so hot & acidic it choked me. It was a yellow phlegm & sounded like congestion in my throat. After spitting all this out, I laid back down for a while & I could hear crackling in my throat. I had eaten around 3:00 pm that day; 3 bites of spaghetti, a salad & one slice garlic bread & nothing else. What was all this & why didn't the Nexium stop it?
