Severe abdominal bloating and generalized abdominal tenderness associated with bloating, especially, prominent in the lower abdomen, is a possible symptom of Irritable bowel syndrome.
Bloating, usually appears after meals, subsides overnight and returns the following day.
Having a bowel movement will or won't ease the discomfort from the abdominal fullness.
Chronic constipation is another symptom of IBS.
Sometimes, lower abdominal pain and bloating can be due to gynecological conditions.
