oh izzit? so it is not related to drinking b4 running? then no choice but to run ady

it's also called side stitch don't you love google
common side stitch is caused by the exertion that running and bouncing forces inside the abdominal walls. Basically, your stomach and other organs - like the spleen and liver - bump into each other as your feet jar the ground causing connective tissue to stretch on the nerves and cause pain. This connective tissue is also attached to your diaphragm which helps with breathing. This pain is usually on the right side and just under the ribs. Exercise like horseback riding, running, and sit-ups are common causes of the side stitch.
Ways to Prevent or Lessen the Pain of the Common Side Stitch:
1) Do not Run on a Full Stomach
2) Decrease Pace and Breath Deeply
3) Pre-Stretch With Side Torso Twists
4) Perform Lower Back and Abdominal Exercises
