The flexor carpi ulnaris is a forearm muscle and can trigger pain in the wrist if it gets overworked or develops trigger points.
On this page you will learn about this muscles’ functions, insertions, pain zones, palpation and massage.
Furthermore, you will get known to what movements and actions are prone to overload this muscle and which movements can be impaired or painful as a result of that.
If your flexor carpi ulnaris is too tight or harbors trigger points, it can trigger pain at the ulnar side/outer side of your wrist.
Furthermore, the pain can radiate into your forearm and hand.
The deeper the red in the picture, the likelier it is to experience pain in the respective area with excessive muscle tension or trigger points being present.
If your flexor carpi ulnaris is very tight or contains trigger points, you might have problems bending your hand and flexing your fingers.
It may become so bad, that even holding a cup of coffee becomes too much.
This is because this muscle can compress the ulnar nerve if it is too tight and thus irritate your nervous system.
Of course, all activities that created the problems in the first place, can be painful too.
What you need to do now, is to locate the tender spots in this muscle and massage them in order to achieve relief.
As its name already suggests, it flexes your wrist.
Furthermore, it deviates your wrist in a way that your pinky is moved towards your forearm.
Last but not least it supports the flexion of your fingers.
As with all the other flexors of your forearm, this muscle gets overloaded by excessive gripping motions.
You will realize that you use your hands to an enormous extend in your daily life.
Still, due to our mostly sedentary lifestyle, those motions are rather „undemanding“ in terms of the load that is placed upon them.
As a result, these muscles are not well trained and more susceptible to trigger points if used heavily.
Here are some common examples that can overload the muscle and/or create trigger points
So, in case, you only get transient relief, check out those muscles!
I recommend feeling this muscle during contraction.
For massage you can use your fingers or a massage ball against a wall.
If you hit it, you will experience a tingling and/or burning sensation, which will be your sign to get back on track onto the muscle.
