Flexor Carpi Radialis Pain And Trigger Points


The flexor carpi radialis can induce pain at the volar side of your wrist if it is overly tight or contains trigger points. It is a muscle of your forearm that helps to move your hand. On this page you will learn about its attachment points, functions, pain zones, overload movements, impaired movements, palpation and self-massage.

Attachment Points And Trigger Points


This muscle runs from the medial epicondyle to the metacarpal bone of the index finger. The X in the muscle picture displays an area that is common for trigger points to set up.



Function Of The Flexor Carpi Radialis


This muscles' function is to flex your hand and to abduct it at your wrist.

Pain Zone Of The Flexor Carpi Radialis


Excessive muscle tension or trigger points in this muscle can induce pain at the volar side of your wrist.


Flexor Carpi Radialis Overuse And Trigger Point Development


Especially excessive use of gripping, twisting and pulling motions will lead to unnecessary tension and the development of trigger points in this muscle.


That means lots of activities of your daily living can create problems. Here are a few examples – all of which include repetitive or excessive gripping, twisting or pulling motions –.


  • wringing out wet towels or clothes
  • driving an old car without power steering hours-long
  • gardening
  • playing tennis
  • playing golf


Beside that, it is important to note that other muscles, located more centrally in your body, can induce satellite trigger points in your flexor carpi radialis if they contain trigger points themselves or are too tight.


That means, all activities that overload those muscles can eventually induce pain at your volar wrist. Before you now freak out and get totally overwhelmed, please don't. Simply spoken it means the following.


If you find trigger points in this muscle, and work them but they reappear all the time and your pain just won't subside, check the muscles listed below. They might contain key trigger points which you have to deactivate for lasting relief.


Impaired Movements


If this muscle is too tight or harbors trigger points, it may be that you feel pain with any motion where you have to flex your fingers and your wrist. It goes without saying that all the activities that are listed under the point “Overuse And Trigger Point Development” are probably painful and impaired.


Palpation


In order to feel this muscle, bend your wrist and make a fist. Now you should be able to see and feel a couple of tendons appearing at your wrist.


Feel the outer one – that is closest to your thumb – and follow its entire length down your forearm. After a couple of centimeters the tendon will transfer into the muscle belly. That muscle is your flexor carpi radialis.You should be able to palpate it all the way down to your medial epicondyle.


Self-Massage Of The Flexor Carpi Radialis 


For massage I recommend using a supported thumb or a lacrosse ball. A tennis ball can be already too soft for massage. Still, you might feel different, especially if your forearm muscles are extremely tender.


With the supported thumb, search for tender spots and massage them with short and precise strokes for about 10 – 15 times.


If you use a ball for massage, place it on the muscle and then lean against a wall. Then roll over it and search for tight and tender tissue and massage it with very short, deep and slow strokes for 10 – 15 times.


Note: I absolutely prefer massaging this area with a ball, for two simple reasons. First, I found the pressure that I can create with my ball – lacrosse ball – more than sufficient to relieve tight tissue. The second reason is, that the lacrosse ball covers more area while exerting pressure and thus also treats surrounding muscles.


As it is very rare that only one of the forearm flexor muscles develops problems in isolation, this is even desirable. On top, this lets me concentrate stronger on finding tender spots instead of staying exactly on the flexor carpi radialis.
