Hi for last few months been experiencing burning sensation just above left belly button also cramp wave like pain in lower left abdomen all happens mostly at night when laying down for the past two weeks stools normal a little white discharge on pape?

The colon takes a 90degree turn at the upper left abdomen and gas can get trapped there. Lower left abdominal discomfort can be seen in irritable bowel syndrome, diverticulitis and inflammatory bowel disease. Mucus discharge from the rectum is not uncommon in irritable bowel syndrome or mucus colitis which may be what you're experiencing& usually loose stools are present. ?Consult a gastroenterolo
