Planckâs theory and thermodynamics. Max Planck described the methods he used to develop his famous blackbody radiation equation in a series of lectures at Columbia University in 1915. These lectures were recorded (1), and the published document is the information source for these articles.
Symptoms will generally only occur when there is a complication. The most common symptom is immense upper abdominal pain, though it may radiate down to the belly button. This pain will occur periodically, occurring every few days, months, or even years. Other symptoms include nausea, vomiting, fever, bloating, belching, and jaundice.
Pain consistently felt over belly button or umbilicus at rest from a diseased organ not underlying umbilicus is called a radiating belly button pain or radiating umbilical pain. Radiating belly button pain or radiating umbilical pain is different than a referred belly button or referred umbilical pain.
