Tennis elbow, also known as lateral epicondylitis, affects the elbow's outside part. It refers to the elbow's lateral inflammation, causing elbow pain and movement difficulty.
The common symptoms include: bending pain, forearm pain, swelling, wrist discomfort, hand tingling. Resting, cold therapy and other non-surgical treatment can often reduce the symptoms. If left untreated, tennis elbow may lead to chronic pain.
Excessive usage and repetitive stress are the major causes, as they can cause elbow joint injuries, especially the tendons. The following activities often have high risks: tennis, racket sports, throwing sports, painting, hammering, repetitive elbow movements.
