It turns out that many people have had chest pains. Some people think it’s a heart attack, and more people don’t hear about it. Yes, it can be a sign of coronary heart disease, but it can also just be a trivial chest wall pain or stomach acid acting up. So, how should you diagnose if GERD is causing chest pain? Here is a brief introduction: The clinical manifestations of GERD are diverse and vary in severity, with some symptoms being more typical, such as heartburn and acid reflux, while others are not easily recognized. Heartburn and acid reflux are the most common symptoms of GERD. Heartburn is a burning sensation behind the sternum or under the xiphoid process, often extending upward from the lower part of the sternum. It often occurs one hour after a meal and can be aggravated by lying down, bending over or increased abdominal pressure. Gastric contents gushing into the mouth without nausea and exertion are collectively called regurgitation. In this disease, the refluxed material is mostly acidic, which is then called acid reflux. Acid reflux is often accompanied by heartburn. 2.Dysphagia and swallowing pain Some patients have dysphagia, which may be due to esophageal spasm or dysfunction, the symptoms are intermittent, myopia solid or liquid food can occur. In a small number of patients, dysphagia is caused by esophageal stricture, in which the dysphagia may be persistently and progressively aggravated. Severe esophagitis or complication of esophageal ulcer may be accompanied by painful swallowing. Poststernal pain: The pain occurs at the back of the sternum or below the xiphoid process. In severe cases, it can be a severe stabbing pain, radiating to the back, chest, shoulders, neck and ears, which is similar to angina pectoris. Most patients develop from heartburn, but some patients may not have the typical symptoms of heartburn and acid reflux associated with gastroesophageal reflux disease (GERD), which makes the diagnosis difficult.
