"Generally speaking, the initial symptoms of the patient are severe nausea and vomiting, followed by chest pain and upper abdominal pain.
Some patients vomited blood or blood - like vomit.
The pain was like being torn apart and unbearable. Even large doses of painkillers could not ease it. Most of the pain was in the upper abdomen, the back of the sternum, the ribs, and the lower chest. Sometimes, the pain shot up to his shoulder and back. When the symptoms are serious, there are obvious shortness of breath, breathing difficulties, cyanosis, and even shock. "
