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.
Tendonitis is the inflammation of the tendons, which are tough bands of tissue that attach muscle to bone. Because tendons are not elastic, theyâre more susceptible than muscles to inflammation, even from overuse. The most common areas affected are the hips, knees, shoulders, heels, and elbows.
