A feeling of gas in the esophagus or upper intestinal tract. a "stitch" is an intermittent pain in the side or flank and characterized by pain on extremes of motion or breathing (Pleurisy or after running getting a side cramp in a muscle) In a message dated 4/23/2011 8:19:09 A.M.

Bilious means nausea. Charles Severs MD
