Tennis is a very dynamic sport that potentially involves a variety of injuries. One of the most common types of injuries in tennis is tennis elbow, an injury to the tendons and muscles on the outer part of the elbow that comes on as a result of repetitive stress or overuse. Term tennis elbow got its name for the reason that tennis players are most likely to get it (although anyone can get it). An extended definition for tennis elbow is: tennis elbow is degeneration or inflammation of the tendon attached to the bony bit on the outside of the elbow or arm.

Exact tennis elbow causes are unidentified, but it is considered to be owing to small tears of the tendons which attach the forearm muscles to the arm bone at the elbow joint. Common tennis elbow causes in tennis players are insufficient grip size or/and bad backhand technique. Small grips make the muscles of the elbow work harder thus causing inflammation of elbow structure. The average age of people who are most exposed to tennis elbow is between 40 and 50 years but the injury can affect players of any age.

Despite its well-defined name, tennis elbow is more often seen in people who overuse their arms doing other work but playing tennis. Among the rest of tennis elbow causes are:
- Excessive use of the muscles attached to the bones in the vicinity of elbow.
- Direct bang or injury may cause of inflammation and damage to the muscules around the elbow.
- Sometimes the elbow inflammation arises without any of the tennis elbow causes mentioned above. This may be due to rheumatism, arthritis, or gout. Quite regularly the disorder or its part is due to the problems with neck. Neck problem may cause the pain in the elbow through the nerves of the neck.


Tennis elbow symptoms and signs include:
- Frequent pain on the outer part of the upper forearm slightly below the elbow bend; sometimes, pain spreads down the arm in the direction of the wrist.
- Difficult to extend the forearm completely (because of inflamed tendons, muscles and ligaments).
- Pain arisen in the result of bending or lifting the arm or clutching even light items such as a tea cup.
- Pain that normally lingers on for six to twelve weeks; the pain can last for as little as three weeks or as long as a few years.
- Weakness in the wrist.
- Pain on the elbow when attempting to straighten the fingers.

The pain related to tennis elbow typically has a gradual beginning, but might also happen suddenly.

Some guidelines on what can affected person do in order to relieve from tennis elbow are:
- Rest. It is a very significant component in the curing of this injury. It can cure rapidly within a couple of weeks but you may suffer with this injury for up to two years.
- Ice the injury up two six times a day for two days.
- Wear a support or brace to protect the tendon while curing and strengthening.

There are more than a few available treatments for the injury of tennis elbow. The good thing is that nonoperative healing is successful in more that 90% of patients. It's worth mentioning that a lot of medical textbooks cure tennis elbow as a form of tendonitis of elbow, which is frequently the case, but if the bones and muscles of the elbow joint are involved as well, then the condition is called epicondylitis.
