Explanation:
Shin splints develop from repeated stress to the shin bone by the pulling and tugging of the muscles and connective tissues in the lower leg. Frequent, repetitive pressure from running and jumping can cause the shin bone to become inflamed (swollen or irritated) and weakened. When the bone does not have time to heal, the damage can get worse and cause severe pain. Anyone who starts a new exercise routine or accelerates their sport or activity too quickly may be prone to developing shin splints.
