What is tennis elbow?
Tennis elbow is soreness or pain on the outer part of the elbow. It happens when you damage the tendons that connect the muscles of your forearm to your elbow. The pain may spread down your arm to your wrist. If you don't treat the injury, it may hurt to do simple things like turn a key or open a door.

What causes tennis elbow?
Most of the time tennis elbow is caused by overuse. You probably got it from doing activities where you twist your arm over and over. This can stress the tendon, causing tiny tears that in time lead to pain. A direct blow to the outer elbow can also cause tendon damage.
Tennis elbow is common in tennis players, but most people get it from other activities that work the same muscles, such as gardening, painting, or using a screwdriver. It is often the result of using equipment that is the wrong size or using it the wrong way.
Anyone can get tennis elbow, but it usually occurs in people in their 40s.
How is tennis elbow diagnosed?
To diagnose tennis elbow, a doctor will examine your elbow and ask questions about the elbow problem, your daily activities, and past injuries. You probably won't need to have an X-ray, but you might have one to help rule out other things that could be causing the pain.
If your symptoms don't get better with treatment, you might have an imaging test, such as an MRI. This can tell your doctor whether a bone problem or tissue damage is causing your symptoms.
How is it treated?
You can start treating tennis elbow at home right away.
After the pain eases, your doctor or physical therapist can teach you rehabilitation (rehab) exercises to stretch and strengthen your tendon. Doing these exercises at home can help your tendon heal and can prevent further injury.
When you feel better, you can return to your activity, but take it easy for a while. Don't start at the same level as before your injury. Build back to your previous level slowly, and stop if it hurts. To avoid damaging your tendon again:
Be patient, and stay with your treatment. You will probably feel better in a few weeks, but it may take 6 to 12 months for the tendon to heal. In some cases, the pain lasts for 2 years or longer.
If your symptoms don't improve after 6 to 8 weeks of home treatment, your doctor may suggest a shot of steroid medicine. This could give you some short-term relief so you can start rehab exercises. Surgery is seldom needed for tennis elbow.
