Tennis elbow usually develops over time due to repeated motions, overuse, and muscle strain. It can affect people of any age, but it mainly affects people between the ages of 30 and 60.Â
Extra stress from repetitive movements can strain your muscles and cause a breakdown of the fibers in the tendon that attach the forearm muscles to the bone in your elbow.Â
Tennis elbow can also be caused by an injury to the arm or elbow or a medical condition that affects the body's connective tissues.
Tennis elbow is common in athletes who play sports such as tennis, softball, and baseball, which puts stress on the arms or elbows. People working as carpenters, plumbers, or in similar jobs that stress the elbows may also develop this condition.
Other less common factors that can increase the risk include smoking, obesity, and certain medications.
