We see a surge in tennis elbow after Christmas - cleaning, shopping, all the chopping and cutting that comes with all that food prep (oddly enough it's not as much from tennis as you'd think!). Suddenly things can start to hurt and the elbow is often the first place to take the hit.
Tennis elbow is a name given to a condition in which the outer part of the elbow becomes sore and tender. Activities such as lifting, gripping, opening jars and twisting of the arm are generally painful.
Tennis elbow (or lateral epicondylalgia to use the medical term!) is usually caused by repeated use of the muscles that straighten the wrist and make you grip, and these attach to your elbow.
