Hi, Approximately two days ago, I began experiencing severe acid reflux accompanied by persistent hiccups. Despite drinking plenty of water, I found little to no relief. Since then, I have developed a continuous pain in the upper right side of my chest that occurs whenever I eat or drink, even with a single sip of water. The pain is sharp and intense, arising immediately upon swallowing, and it often radiates toward my back. Interestingly, the discomfort seems to improve when I am lying down or asleep. Given these symptoms, I would like to understand what could be causing this condition.
