Tennis Elbow (Lateral Epicondylitis) is a medical condition in which the outer part of the elbow becomes sore and tender at the outer part of the elbow. This is an overuse injury involving damage to the forearm muscles and tendons from repetitive overuse. Any activity (typically playing tennis) that involves extensive use of the extensor muscles of the forearm can be a risk factor for tennis elbow. This can include carpenters or other labourers swinging a hammer or other tool as part of their occupational duties. Typical symptoms are pain and tenderness at the outer part of the elbow. Pain may also be associated with gripping, lifting and wrist extension (e.g. turning a screwdriver) movements. A tennis elbow brace (band or sleeve) designed to apply pressure to the injured tendon can reduce the pain and discomfort being experienced as well as aid in healing the condition.
