I've been having general, dull abdominal pain the last 4 days (more specifically in the umbilical region). I've had bloating, tenderness, gas, and constipation the last 4 days. Today, the pains are slightly worse, with the addition of nausea and occasional burping. I have been able to pass 3 bowel movements today, well-formed and light brown. I've been extremely tired the last couple of days, and have a headache today. My temperature is 37.2 degrees Celcius.
