Muscle Strain Overview
Muscle strain is injury to muscle as a result of strenuous activity. Almost anyone can put undue tension on muscles during the course of normal daily activities, with sudden, quick heavy lifting, during sports, or while performing work tasks. Muscle strain is sometimes referred to as muscle pull. A severe muscle strain can result in a muscle tear. The tearing of the muscle can also damage small blood vessels, causing local bleeding (with or without bruising) and pain (caused by irritation of the nerve endings in the area). Of note, a sprain, in contrast to a strain, is an injury to ligaments.
