A strain is a twist, pull and/or tear of a muscle and/or tendon. Tendons are fibrous cords of tissue that attach muscles to bone. Strains and sprains are among the most common sports injuries.
Although tendonitis can result from an acute injury, it is usually the result of a repetitive muscle force, placing persistent strain on a tendon. Some of the more common forms of tendonitis include laterl/medial epicondylitis, patellar tendonitis achilles tendonitis, rotator cuff tendonitis and plantar fasciitis.
