Which of the following will prevent further shin split injury?

a. changing to play on a hard surface
b. resting until the discomfort goes away
c. finishing by taking off your footwear
d. moving more quickly to minimize the discomfort

The answer is B. resting until the discomfort goes away. 
Other choices require further movement that may worsen the shin split. 

The pain of the injury is triggered when a movement like running is done. The best way to lessen the pain is through resting. With this kind of condition, running is impossible to do. So it's better to avoid foot regular movement and exercises. The best way to cure this is treatment from a doctor.
