On this page I will guide you through the insertions, functions, pain zones, overload movements, impaired movements, palpation and massage of this muscle.
In a nutshell: All the information you need to understand why this muscle might be troubling you and how to deal with it.
If this muscle contains trigger points or is too tight, it gets tender and can trigger pain at the lateral epicondyle of your humerus – outer side of your elbow joint – which is often diagnosed as tennis elbow pain.
Furthermore, it might leave you with pain at the backside of your hand – area between thumb and index finger –.
If this muscle is excessively tight and/or contains trigger points, you might feel pain when using the muscle and even afterwards at rest.
Thus, all the movements that occur with the activities displayed above may be painful and/or impaired.
