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.
This is often due to the tendons and bursae in the joints. Tendons are bands of thick tissue that attach muscles to bone but they lack elasticity, and can be easily pulled during movement. Tendonitis is the inflammation or irritation of the tendon(s); the condition can vary and may result in aches, pain and stiffness.
