One of the most common and painful injuries in sport is the hamstring strain. Hamstring strains occur frequently among activities that require a high degree of speed, power and agility such as soccer, running, basketball and dancing. A hamstring strain can range from mild to very severe involving a complete tear of the hamstring muscle.
Headaches affect just about everyone at some point and they can present themselves in many different ways. Some people only experience pain in one part of their head or behind their eyes, some people experience a pounding sensation inside their whole head, and some people even experience nausea.
