I have a pretty good size beer gut but have noticed lately belly hurts a little when I yawn and also have abdominal pain and cramping?

Get up and exercise! Mild abdominal pain and cramping with a large obese abdomen is a sign that your diet and/or lifestyle is horrible and in need of a major overhaul. Furthermore, welcome to aging. You're 33 years old, and already showing signs of age-related decline. Schedule an appointment with your PCP and get into shape. You may have underlying conditions that are more problematic in the long-run than obesity. .
