Functional dyspepsia
Hiatus hernia
Jackhammer esophagus (hypercontractile peristalsis): Intense long-lasting esophageal muscle spasm. Acute cholecystitis: Characterized by positive Murphys sign where the person has a cessation of inhalation when the doctor places his finger at the right subcostal region of the abdomen. Acute pancreatitis: History of excessive alcohol use, cholelithiasis (stones in the gallbladder), and hypertriglyceridemia are risk factors for pancreatitis. It is a constant, boring pain in the upper abdomen. Perforated peptic ulcer: Sudden onset of severe pain in the upper abdomen which later develops into peritonitis (inflammation of tissues that lines the abdominal organs). Acute gastritis

Chest wall
Costochondritis or Tietzes syndrome: An inflammation of a costochondral junction. Any movements or palpation of the chest can reproduce the symptoms. Spinal nerve problem
Fibromyalgia
Chest wall problems
Radiculopathy
Precordial catch syndrome: Another benign and harmless form of a sharp, localized chest pain often mistaken for heart disease. Breast conditions
Herpes zoster (shingles): It is usually described as a burning sensation over the chest in a unilateral dermatome distribution. However, diagnosis can be difficult because the pain usually appears before the characteristic rash is visible. Tuberculosis
Osteoarthritis
Bornholm disease
Rib fracture

Psychological
Panic attack: Chest pain is a common symptom of panic attacks, with as high as 78% of persons describing chest pain with their worst panic attacks. Overall chest pain is a symptom of up to 48% of sudden-onset panic attacks, and 10% of gradual-onset panic attacks. Anxiety
Clinical depression
Somatization disorder
Hypochondria

Others
Hyperventilation syndrome often presents with chest pain and a tingling sensation of the fingertips and around the mouth.
The high pressure rips the tissue of the media apart along the laminated plane splitting the inner two-thirds and the outer one-third of the media apart. This can propagate along the length of the aorta for a variable distance forward or backward. Dissections that propagate towards the iliac bifurcation (with the flow of blood) are called anterograde dissections and those that propagate towards the aortic root (opposite of the flow of blood) are called retrograde dissections. The initial tear is usually within 100 mm of the aortic valve, so a retrograde dissection can easily compromise the pericardium leading to a hemopericardium. Anterograde dissections may propagate all the way to the iliac bifurcation of the aorta, rupture the aortic wall, or recanalize into the intravascular lumen leading to a double-barrel aorta. The double-barrel aorta relieves the pressure of blood flow and reduces the risk of rupture. Rupture leads to hemorrhaging into a body cavity, and prognosis depends on the area of rupture. Retroperitoneal and pericardial ruptures are both possible. The initiating event in aortic dissection is a tear in the intimal lining of the aorta. Due to the high pressures in the aorta, blood enters the media at the point of the tear. The force of the blood entering the media causes the tear to extend. It may extend proximally (closer to the heart) or distally (away from the heart) or both. The blood travels through the media, creating a false lumen (the true lumen is the normal conduit of blood in the aorta).
