What are the causes of having sharp pain just above belly button when pressed?

Pain over the location just above the belly button usually indicates issues with the stomach. This is especially so if the pain or discomfort is associated with your meals or occur more frequently at night. In some cases, there is a sensation of "burning" discomfort that travels up the chest wall or throat discomfort especially in the morning with a bitter or sour taste in your mouth. Having said that, there are conditions that affect other organs near the stomach which may give rise to similar discomfort.
