A pain hard to pin down

If you jog you are probably familiar with the pain in the lower abdomen area known as a side stitch. It makes jogging impossible but what causes it?

"The problem with side stitch is always the same: whenever a doctor wants to examine it, it's gone," says Klaus Voelker, professor of sport medicine at the University of Munster in northern Germany.

The phenomenon always occurs during physical exercise but with a few simple behavioral changes you can avoid the pain or get rid of it quickly.
