Why do you get tennis elbow from playing tennis?

Tennis elbow refers to epicondylitis of the humerus. Possible reasons for getting epicondylitis of the humerus from playing tennis include using equipment that is too heavy, incorrect training methods, and not warming up sufficiently before the activity.
Tennis elbow, as the name suggests, is the gradual onset of pain and burning on the outside of the elbow joint triggered by sports injuries caused during tennis, also known as epicondylitis humeri.
It occurs when the arm is weak, when equipment is used that is too heavy for the muscles to take the intense pull or when the training method is incorrect and the forearm muscles are overexerted.
In addition, it may also be due to the lack of adequate warm-up before the activity, the muscle from static suddenly to the strenuous activity state and caused a local injury, the emergence of humeral epicondylitis.
So before playing tennis, you should warm up properly, choose the right equipment for yourself, use the right way to exercise, and seek medical attention for any discomfort.
