Hernia problems are common in football as the pelvic region is subject to considerable stress during matches and training. It is caused by a tear to the stomach muscles when part of the intestine or stomach bulges through the hole and forms a painful lump. In most cases a hernia is simply a painful nuisance and it is usually possible to continue playing by wearing special clothing until a convenient time can be arranged to undergo surgery.
