Tennis Elbow (Extensor Tendinopathy) & Golfer's Elbow (Flexor Tendinopathy)
So named as they are common injuries amongst tennis players and golfers, Tennis Elbow and Golfer's Elbow does not just affect those who play these sports. In fact it is sometimes more common to see them presenting in people who play neither sport. They are both overuse injuries, resulting in damage to the wrist extensor and flexor tendons respectively.
Tennis Elbow is the more common injury of the two. It presents as pain on the outside of the elbow, and often refers down the forearm to the wrist. Sufferers complain of pain and weakness on gripping activities, such as lifting the kettle or carrying a heavy shopping bag. Often mouse usage is an aggravating factor.
Golfers Elbow is very similar, however the pain is felt on the inside of the elbow. Again gripping activities are what usually bring on the pain for sufferers, especially those that require you to flex (curl) the wrist at the same time.
