Pain pattern front part
The deltoid muscle is one of the troublemakers when it comes to shoulder pain.
It also may be responsible for your impingement syndrome.
This muscle builds the top layer of your shoulder joint.
If you are a well-trained person it may give you a beautiful shaped shoulder. But if you overwork your shoulders, there is a good chance that it will trouble you.
As you can see in the pictures below, pain created by trigger points in the deltoid muscle is mainly felt in your arm and shoulder.
Here, pain will arise in the vicinity of the trigger points.
That means, if trigger points are located at the front, side or back part of the muscle, you also will experience pain in the front, side or back part of the muscle and shoulder, respectively.
That information will make it easier for you to find out, where trigger points might be located in your case.
Also study the location of the trigger points – X1 to X6 – under attachment points of the muscle.
The muscle can be involved in the following symptoms:
Note: Do not forget to also check other muscles for trigger points when your shoulder is painful.
It is very seldom that trigger points in the deltoids are the primary reason for shoulder pain.
More often other shoulder muscles are the main troublemakers.
If you have a very tight deltoid or one that contains tender or trigger points, you may be confronted with some difficulties in your activities of daily living.
Combing your hair, reaching to your mouth or lifting your arm may become very painful if trigger or tender points are present.
Even a lack of strength in the affected shoulder and arm is a common thing when you have tender or trigger points in this muscle.
