Muscle deep-dives
Extensor Carpi Radialis Longus trigger points: referred pain, palpation and release
A clinical deep-dive on Extensor Carpi Radialis Longus: trigger point locations, the referred pain pattern they produce, palpation landmarks, activating factors and an evidence-based release protocol.

Why this muscle causes pain
Extends and radially deviates the wrist. Trigger points here are common in everyday and athletic populations and frequently contribute to the referred pain patterns described below.
Where the trigger points sit
Dorsal lateral forearm just distal to the lateral epicondyle.
The referred pain pattern
Lateral elbow and the dorsum of the hand — classic 'tennis elbow' presentation.
How to find it by palpation
Palpate the muscle belly along its accessible course. Reproduction of the patient's familiar pain on palpation supports involvement.
What sets it off
Mouse use, racquet sports, repeated gripping.
Self-care that actually helps
Eccentric wrist extension, grip strengthening. Clinically: needling, address grip ergonomics.
Symptoms this muscle produces
Clinically, this muscle turns up in the workup of dorsal forearm pain, dorsal wrist & hand pain, elbow pain, lateral epicondylar pain and thumb & radial hand pain. Those are the complaints its referral zone overlaps, which is why a patient may present with any of them and never mention the muscle itself.
