2. Abdominal Pain
The main symptom of pancreatitis (both acute and chronic) is pain in the upper abdomen. This pain might also spread into the back. According to NIDDK, the abdominal pain in acute and chronic pancreatitis is felt differently.
When it comes to acute pancreatitis, the pain begins in the upper abdomen and then sometimes spreads into the back. It can be mild or severe, and may last for several days, says NIH.
With chronic pancreatitis, the pain also begins in the upper abdomen, but some patients report not feeling any pain at all. If they do have pain, the source notes that it can also spread to their back, be “constant and severe, worse after eating,” and go away as the condition gets worse.
