Flank Pain. It is more localized and is described as a sharp pain. These are patients with localized peritonitis indicative of appendicitis, rupture, or perforation. Abdominal pain occurs when mechanical or chemical stimuli trigger the pain receptors in the abdomen. Stretch is the primary mechanical stimulus.
Other mechanical stimuli, such as expansion, contraction, compression, pulling, and twisting of the viscera, also induce pain. Types of Abdominal Pain Visceral pain. Chronic abdominal pain is pain that is present for more than 3 months. It may be present all the time (chronic) or come and go (recurring).

The acid test of Waiter Palmer precipitated the pain, and a strict ulcer)"(~g;imen gave prompt and lasting relief.
Although the biliary tract, pancreas, stomach, and duodenum derive their sensory innervation from the 4th to 9th thoracic segments, in these two patients the pain was localized to two segments. Most Common Causes of Upper Left Abdominal Pain Peptic Ulcer Disease.
Ulcers in the stomach and duodenum are top causes. They can be caused by a myriad of problems, most related to use of Anti-inflammatory medication or steroids. Helicobacter Pylori is an infection that causes ulcers as well and requires antacid as well as antibiotic therapy.

Moderate pain in the epigastrium (the mid-upper abdomen) is present with ulcer disease of the stomach or duodenum, early appendicitis, hiatal hernia and gallbladder disease. A sudden, complete obstruction of the superior mesenteric artery, a major branch of the abdominal aorta that supplies a large part of the intestine, is an emergency.
