Jaw shifted to the side (lateral).
The medial pterygoid is a muscle of your temporomandibular joint and can cause pain in the jaw, throat and ear if it is tense or carries trigger points.
However, it’s possible to eliminate these points and tensions with a self-massage.
On this page you will find instructions how to do this.

Trigger points in the medial pterygoid can lead to the following ailments.
In general, the pain caused by this muscle is rather diffuse and not clearly distinguishable.
The pain usually increases when you stretch or contract the muscle.
Each time the jaw is opened, the muscle is extended, and each time the jaw is closed, it is contracted.
That means the pain could be increased by …
Besides pain, there may be difficulty swallowing or pressure on the ears.
The pressure on the ears stems from the fact that trigger points in the pterygoid disrupt the function of the tensor veli palatini.
This muscle is responsible for pressure balance in the ear. If the muscle can no longer work “properly”, this may impair this function.
Concerning the function of the muscle, we must distinguish whether it is active on both sides of the jaw (left and right), or only on one side.
Unilateral contraction: The muscle shifts the lower jaw to the opposite side (excursion of the mandible).
A function that is very important for grinding food during mastication.
Performing bilateral contraction, the muscle closes the jaw. It is supported by the masseter, the upper fibers of the lateral pterygoid and the temporalis.
In addition, contraction on both sides contributes to a forward shift of the mandible (protrusion).
Trigger points arise in this muscle primarily due to unfavorable postures, active overload, emotional tension or because of satellite trigger points.
Any posture or activity in which the head is moved forward, moves the lower jaw into a position that puts this muscle under tension.
In the long run, this can overload the medial pterygoid and activate trigger points.
The muscle is actively overloaded if you strain it beyond its level of performance.
Especially repetitive movements cause problems.
Emotional tension is generally reflected in an increase of muscle tension. The primarily affected muscles vary from person to person.
However, many people’s jaw muscles are particularly sensitive to stress and deep emotions.
Over time (hours to weeks, depending on the individual) this can lead to tension and trigger points.
Satellite trigger points are those that arise as a “reaction” to trigger points in other muscles.
In this case, it is the lateral pterygoid that can activate these satellite trigger points in the medial pterygoid. It is therefore worthwhile to have a look at it, too, and to massage it if necessary.
It is not easy to palpate the muscle or to feel its fibers contracting. Nevertheless, I’ll provide you with an instruction – for all those who would like to try it.
Do not worry if you don’t want to try it or if you are unable to feel the muscle. Even so, you will find the area to be massaged without any problems.
The palpation of this muscle is performed intraorally, i.e. you have to put your fingers into your mouth. That’s why I first of all recommend washing your hands.
Furthermore, you should take it slowly. In order to feel the muscle and to perform the self-massage, you have to reach quite deep into your mouth which could evoke the pharyngal reflex. Slow approach helps to avoid that.
Now you are in the area of the medial pterygoid. You will massage this area in the next chapter. To feel the muscle under tension, proceed as follows:
If you don’t have a cork at hand, bite your finger. Of course, you cannot bite hard, but it’s still possible to feel the muscle’s contraction.
Use your fingers for the massage. As massage technique, I recommend the …
You can massage the muscle from the outside (extraoral) or inside the mouth (intraoral). On this page I show you the intraoral massage with precise massage strokes.
Note: For the massage of this muscle, there is no need to exert intense pressure!
