Local anesthesia is believed to break the cycle of pain that can cause you to become less physically active. Muscles that are not being exercised are more easily injured, so the irritated and injured muscles can cause more pain and spasm and can disrupt sleep. This pain, spasm, and fatigue, in turn, can lead to less and less activity.
