Tennis elbow will get better with treatment gradually because it is a self-limiting condition.
As the healing of tendons takes place slowly, it can take several months or weeks. There have been cases where tennis elbow has persisted for more than a year.
However, there are various simple treatments that can help reduce the pain. It is very important to rest the injured arm and immediately stop the activity that caused the pain and rest the injured elbow.
A cold pack or cold compress like a bag of frozen peas applied against the elbow many times for few minutes can ease the pain. The cold compress must be wrapped in a towel and should not be applied directly.
When non-surgical treatments are rendered useless, and if the pain has been continuing for a long time and is severe, one can resort to treatments like surgery.
