In the case of acute pancreatitis, abdominal pain will appear at the onset of the disease, and abdominal pain is the first and most prominent clinical symptom. The abdominal pain is often severe and persistent, mostly distension, dull pain, colic, knife-like pain, etc. There is also radiating pain. And this pain can not be relieved by the general gastrointestinal antispasmodics, and will be more painful after eating. In the case of chronic pancreatitis, the main manifestation at the beginning of the disease is intermittent pain, which may occur once every few minutes, and may be vague and bearable at first. But at the later time the intermittent hidden pain will evolve into persistent pain, which may become more and more severe, or even severe pain. Patients with pancreatitis must be hospitalized and cooperate with the doctor to use drugs that inhibit the secretion of pancreatic enzymes, and may need temporary painkillers if necessary.
