Tennis elbow, also known as lateral epicondylitis, is the persistent pain in the outer side of the elbow. In comparison, Golfer's elbow is the pain on the inside of the elbow.
Tennis elbow is caused by a repetitive injury to a tendon in the elbow, from an overuse of the forearm muscles attached to the tendon. This type of injury can be caused not just by playing tennis but also by other sports or some work-related movements.

Tennis elbow is a type of overuse injury that affects the tendon attached to the extensor muscles in the forearm. The extensor muscles help pull the hand back and aid turning the arm so that the palms face upwards. The tendon for the extensor muscles of the forearm is attached to the outer side of the elbow joint. Repeated overuse of the extensor muscles can cause minor injuries to the tendon (known as tendinopathy). If these injuries are not adequately healed by the body, the tendon damage can accumulate and lead to persistent inflammation and pain.

Risk factors for tennis elbow include:
Signs and symptoms of tennis elbow include:
Your doctor will diagnose tennis elbow after performing a physical exam and asking you questions about your pain and activities. Rarely, additional tests such as X-rays or ultrasound may be needed to exclude other causes and/or assess the severity of tendon damage.

There are numerous treatment options for tennis elbow. Initially, rest and heat or ice packs may provide relief. Other treatments include:
A strap used to apply pressure to the muscles in the forearm can reduce pressure on the injured tendon. Arm braces can be used during sport or work. Wrist splints, which prevent full forearm movement, are not a substitute for arm braces and should be avoided.
Exercises to improve muscle flexibility can improve arm strength and mobility.
While sitting or standing upright, you can hold your arm outstretched and point your fingers down to the ground. Then hold the hand of your injured arm with your other hand, and pull back on it to stretch the forearm muscles. This stretch may be held for 30 seconds, repeated three times and performed daily.
A flexibility exercise.
A special type of exercise, called eccentric strengthening, can be used once flexibility has improved and no pain is felt when performing them. This exercise involves the use of a weight or elastic band to provide resistance.
To perform this exercise, lie down on a bed. Rest your out-stretched arms on the bed, with your hands hanging over the edge of the bed and the palms facing the floor. From this starting position, use a half-kilogram weight in your hand, then gradually bend your wrist back, then return it to the starting position. This is ideally performed ten times, which is known as a 'set', then repeated for another two sets, with a one-minute rest in between. It is generally advised that these exercises be done every day and the weight increased when the exercise can be done without pain.
Pain-relief medications, such as acetaminophen or ibuprofen, can help manage the pain. If the pain is ongoing, your doctor may suggest injections of corticosteroid anti-inflammatory medication, around the injured tendon.
Surgery is used as a last resort, when other treatment options have failed to alleviate pain after several months. Surgery can include dividing the tendon, removing the damaged area of the tendon and/or repairing the tendon.

Aside from pain, the major complication of tennis elbow is that it impedes your ability to perform physical activities, such as certain sports or types of work.
You may experience pain for several weeks during certain sports or work-related activities. Most people respond to treatment, but some will require rehabilitation with a physiotherapist.
