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.
Ache in the Belly Button Area. Though most people associate appendicitis with intense pain in the lower-right side of the abdomen, more often than not, thatâs not how it begins. The earliest sign is an ache in the belly button area that soon travels to the lower portion of the abdomen. The pain in the belly button area occurs because the nerves of the appendix meet the spinal cord at the same level as the belly button. When the appendix is inflamed, therefore, pain is first felt in this area. The ache can get very intense and be exacerbated by movement or sudden jerks to the body.
