Tennis elbow, also known as lateral epicondylitis, is a painful condition caused by overuse of the elbow. Racquet sports like tennis can cause tennis elbow, but several other sports and activities can also put you at risk.
The ulnar nerve sends signals from the neck to the hand and is one of the three main nerves that run through the arm. When the ulnar nerve is compressed, most often in the area behind the inside of the elbow, numbness and tingling in the hands and fingers can result. Ulnar nerve entrapment can often be treated non-surgically with bracing and lifestyle changes, but in more severe cases surgery may be recommended.
Tears of the biceps tendon at the elbow are uncommon, but can result in permanent loss of function in the arm if not treated properly. Surgery is usually recommended to treat tendon tears, but may not always be necessary.
