Tendinitis OverviewTendons are cords of tough, fibrous connective tissue that attach muscles to bones. Tendinitis is an inflammation of the tendon. The condition may also involve the tendon sheath, usually close to where the tendon joins the muscle. Tendinitis is also informally spelled tendonitis. Tendons are generally healthy structures that appear glistening white to the naked eye. If you've ever carved a turkey, the tendons are the tough bands you cut through to get the drumsticks apart. Tendinitis CausesThe most common cause of tendinitis is overuse and repetitive motion from recreational, athletic, or occupational activities. Risk factors for tendonitis include repetitive movement, trauma, thermal injury to the tendon, use of certain antibiotics (such as levofloxacin and ciprofloxacin), and smoking. Tendinitis can also occur in people with diseases such as rheumatoid arthritis, obesity, and diabetes. These are some of the more common forms of tendinitis:

Sprains and Strains Overview
The body is meant to move. Muscles allow that movement to happen by contracting and making joints flex, extend and rotate. Muscles attach on each side of the joint to bone by thick bands of fibrous tissue called tendons. When a muscle contracts, it shortens and pulls on the tendon, which allows the joint to go through a range of motion.
A strain occurs when the muscle tendon unit is stretched or torn. The most common reason is the overuse and stretching of the muscle. The damage may occur in three areas:
- The muscle itself may tear.
- The area where the muscle and tendon blend can tear.
- The tendon may tear partially or completely (rupture).
Joints are stabilized by thick bands of tissue called ligaments which surround them. These ligaments allow the joint to move only in specific directions. Some joints move in multiple planes; therefore, they need mor...
