Upper Left and Right Abdominal Pain

Upper Abdominal Pain

Any abdominal pain can be so excruciating or unbearable  that the patient may  jump, shout or writhe in pain.  Usually the symptoms that accompany abdominal pain include: nausea, vomiting, chills and shivering, burning sensation, diarrhea, mild or severe fever. These symptoms and the location of the pain help in the correct diagnosis of upper abdominal pain.

The upper abdomen is located between the lower ribcage margins and the naval. It is further divided into upper left abdomen and upper right abdomen. Another way to describe it is the center of body from under the breast-bone to umbilicus and across to both sides of the torso.

Any pain in the upper abdomen region is termed as upper abdominal pain. Because of the numerous organs or structures in the upper abdomen it is difficult to diagnose the actual cause of pain. Any disorder or medical condition pertaining to these organs or structures can lead to upper abdominal pain. Sometimes a patient can experience upper abdominal pain due to organs or structures not located in the abdomen.  The illustration of abdominal quadrants can help you describe the location of the pain.
