Hi doctor! I have a phenomenon of choking and tightening my chest, I have to take a deep breath to feel comfortable, but sometimes I can only breathe in to my neck or chest, when I hiccup or burp or yawn, it's comfortable, but sometimes yawning and burping can't get gas. only down to the neck. I went for blood tests, heart and lung exams but there were no problems, gastroscopy showed gastritis. I've been taking the medicine for almost 2 months but it doesn't help, it's comfortable lying down, but when I wake up, my chest is heavy and I have to breathe in to be comfortable, I'm always tired. So the doctor asked me to ask if my child's throat is choking, tightening his chest, gastritis taking medicine for 2 months does not help, what should I check? I always have a stuffy nose and a lot of phlegm in my neck. Ask your doctor for advice and answers. I sincerely thank you!
