Tennis elbow is caused by overuse of the muscles and tendons in your forearm near to your elbow joint. It's caused by any activity that involves repetitive movement in your elbow, wrist and forearm.
It can affect anyone but is most common in people aged 30–50 years. Although movement of your elbow joint isn’t restricted, it can be painful and make some everyday tasks difficult.
In most cases, tennis elbow goes away after about a year with simple treatments and avoiding the repetitive activity that caused it.

They'll then be able to advise an effective tennis elbow treatment.
If you stop the activity that caused it, tennis elbow may eventually go away by itself. However, there are some things you can do to help reduce pain and speed recovery:
In severe cases, tennis elbow treatment may involve tendon surgery.
