Hi Ladies been feeling worse since last week. Light headed, waking up absolutely sweating, rapid heart, nausea to the point of coughing and vomiting phlegm, feeling fatigued, hoarse throat, bit short of breath and cough. Anyway felt that bad that went to walk in centre this morning convinced I had heart or lung problems. All bloods fine. ECG fine, listened to heart and lungs - all fine. See doctor on duty. Told him my symptoms and that I felt quite ill. He asked about poop, I said it had gone lighter. He asked about stomach, said it always feels tender and knotted. He pressed on different areas of stomach and I nearly hit the roof. He said I definitely have gastritis. He explained that the acid builds up overnight and wakes you in a bad sweat, then nausea and vomiting can start. He has put me on Omeprazole. I could not believe that rapid heart can be caused by acid plus my other symptoms. Will see how symptoms go on the meds.
