What causes stitch?!
Question:
What causes stitch?

During exercise, blood moves away from the diaphragm to our limbs. The diaphragm is the muscle that separates the stomach and abdomen from the heart and lungs and is one of the main muscles involved in breathing. Most scientists believe the pain is caused by a reduction in blood supply to the diaphragm, causing it to cramp, and secondly:
It's caused by fluids which the body finds hard to digest. This, in turn, causes the gut to 'tug' on the ligaments connecting it to the diaphragm, and this causes the pain.
