What pain can be mistaken for pancreatitis?

When Abdominal Pain Isn’t What You Think

Severe abdominal pain can be misleading. Often, people experiencing pancreatitis don’t immediately recognize it for what it is. Instead, they might assume they’re dealing with something more familiar—like kidney stones, a stomach ulcer, or a bout of intense heartburn. The truth is, pancreatitis doesn’t always announce itself with textbook clarity.

As inflammation in the pancreas builds, the discomfort typically intensifies, often radiating to the back and worsening after eating. This makes digestion a challenge, and even drinking fluids can feel unbearable. Because the pain is deep and persistent, it's easy to misinterpret it as gastrointestinal distress or a passing issue.

Dr. Sarah Lin, a gastroenterologist at Boston General, explains, “Many patients come in convinced they’ve developed a stomach ulcer or even acid reflux gone wild. But when we look closer—through blood work and imaging—we find the real culprit: an inflamed pancreas.”

What complicates diagnosis further is that conditions like gallstones or chronic acid reflux share similar symptoms. Even kidney stones can mimic pancreatitis, especially when the pain is sharp and centered in the upper abdomen. Unlike heartburn, though, pancreatitis-related pain doesn’t usually respond to antacids.

“I had terrible pain for two days and thought it was just bad indigestion,” recalls James W., a 48-year-old teacher who was eventually diagnosed with acute pancreatitis. “I never considered it could be something deeper.”

Recognizing the difference matters. Early intervention can prevent complications like infection or long-term damage to the pancreas. If abdominal pain lingers, worsens with meals, or is accompanied by nausea and fever, it’s worth seeking medical evaluation—not just assuming it’s another bout of heartburn. Sometimes, the real problem is hiding just beneath the surface.
