Laser therapy can help tennis elbow and golfer’s elbow. These are both types of tendinopathy or tendinosis, which means you have damage in the tendons around your elbow from overuse. Despite the names, the injuries aren’t limited to golfers or tennis players. You’re just more likely to get them based on the arm motions used in those sports. The main difference between the two is that tennis elbow affects the outside of your elbow, while golfer’s elbow affects the inside. Treatment with laser can promote healing and relieve pain.
