Many possibilities: Pain under the left ribs can be caused by many things, including peptic ulcer disease, spleen problems, constipation, diverticulitis, pneumonia, and yes, gas. Determining the cause of pain in the abdomen requires a thorough investigation of symptom timing, duration, character, etc. Abdominal cramping after coffee and cream could be ulcer or gastritis, irritable bowel syndrome, a food allergy, etc.
