In football, the injury usually is caused by the player slamming into a hard object such as the turf. Correct padding is the best prevention. This causes the nerves coming out of his spine and passing toward his arm to suddenly stretch or compress, which sends a burst of nerve messages streaming down the arm. The arm feels numb, weak and tingly, and while the pain tends to go away soon, the weakness may persist for years. Protecting the arm, resting it, and using ice and compression for swelling and pain can help alleviate the condition.
Most stingers heal by themselves.
Turf toe is an irritation of the joint at the base of the first or big toe. It usually happens when the toe is forcefully jammed against the ground or bent backward. The injury is more common in players playing on hard surfaces, such as artificial turf. The result is pain and swelling at the base of the toe, which hampers the athlete, especially when walking. The injury can be diagnosed by a physical exam and an X-ray.
