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.
1 Localized pain: This is pain found in only one area of your belly. It is more likely to be a sign of a problem in an organ, such as the appendix, gallbladder, or stomach.  Cramp-like pain: This type of pain is not serious most of the time. It is likely to be due to gas and bloating, and is often followed by diarrhea. More worrisome signs include pain that occurs more often, lasts than 24 hours, or occurs with a fever.
