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.
Tendinitis is inflammation of the tendons, which are the tapered ends of muscles that attach to bones. Tendons are in action every time muscles contract and bones move. As such, tendonitis is often the result of overuse, such as repetitive movements at work. Tendonitis can theoretically affect all tendons, but the wrist, elbow, shoulder, hips and heel (Achilles tendon) are the areas most commonly inflamed.
