Laser therapy, also known as low-level laser therapy (LLLT) or cold laser therapy, is a type of treatment that uses low-level lasers or light-emitting diodes (LEDs) to stimulate healing and reduce inflammation. It is thought to work by increasing blood flow to the treated area, which can help to reduce inflammation and promote healing.

Tennis elbow, also known as lateral epicondylitis, is a condition that causes pain and inflammation in the elbow and forearm. It is often caused by overuse or repetitive strain on the muscles and tendons in the elbow and forearm. Laser therapy may be used to help reduce pain and inflammation in people with tennis elbow, and may also help to improve range of motion and function.

It is important to note that laser therapy is not a standalone treatment for tennis elbow and should be used in combination with other treatments such as physical therapy and rest. It is also important to consult with a healthcare professional before starting any new treatment.
