Trapezius Muscle Pain Symptoms, Causes & Treatment

Trapezius Muscle is a large superficial muscle that covers the neck, shoulder, and upper back regions. This muscle is formed from three parts: The Superior fibers of the trapezius (upper Region), Inferior fibers of the trapezius (Lower region), and the ascending(vertebrate) part of it.

Origin and Insertion of Trapezius Muscle


Anterior, superior and lateral parts of the nuchal ligament- spinous processes of C7, T1 vertebrae.

Spinous processes of upper thoracic vertebrae (T2 to T5), the medial 1/3rd of the clavicle.

Ramus of Spine(C7) and medial border of the acromion.

Trapezius Muscle function

The main function of the trapezius is to move the scapula and support the arm in movements at the shoulder. In addition, it also helps in keeping the head upright as well as helps during the swallowing process as a neck muscle.

In the case of lower fibers, they aid in keeping the shoulder blade in place.

What is Trapezius Muscle Injury?


Trapezius muscle injury can be caused by a variety of reasons including acute trapezius strain, chronic trapezius strain, and trigger points, etc. This condition is complex to diagnose and treat as it involves adjacent structures such as cervical spine region muscles.

Trapezius Muscle Spasm

A trapezius muscle spasm is a situation where the muscle becomes suddenly rigid and painful. This is due to an injury or inflammation in this muscle which has a reduced blood supply. This muscle spasm can be caused due to trapezius trigger points, trauma, strain, or prolonged poor posture.

This condition can be diagnosed by a thorough clinical examination, patient history, and medical imaging. The treatment of this condition depends on the cause but in the majority of the cases, this problem can be resolved with proper treatment.

Trapezius Muscle Strain

Muscle strain is a situation where this muscle is injured by overusing or stretching. This can be caused due to improper posture, poor training methods, sudden jerking movements, etc.

How To Do Trapezius Muscle Pain Treatment At Home?

Trapezius muscle pain treatment at home involves the proper diagnosis of the condition, home remedies, and physiotherapy for complete recovery. Certain factors like pain severity, location of injury or inflammation, etc. should be considered before starting any kind of home remedy approach.

What Are The Common Causes Of Trapezius Muscle Strain?


The most common causes of a trapezius muscle strain are poor posture during work/driving, sudden jerking movements which can lead to a spasm or tear in this muscle, and overuse that is seen in weight lifting exercises, etc. Other than these, trapezius trigger points can also be an important cause behind this problem.

Trigger Points In The Trapezius Muscle And Their Symptoms

A Trigger Point is a hyperirritable area within the muscle that produces pain locally and is referred to as other areas of the body. The major symptom of trigger points is stiffness or ache in this muscle region.

Sometimes,  a patient may also complain of confusion with previous injuries or muscle problems from their past. Trigger Point causes trapezius muscle strain when it places pressure on the nerve supplying this muscle.

Where Is The Best Place To Inject Trapezius Muscle?

Anatomy of the man, body builder.

Injection treatment for trapezius muscles strain must be done into the affected muscles at proper anatomical landmarks only. There is no best place to inject in this condition as its location will vary depending on various factors such as severity, duration, and type of injury, etc. However, the major injection sites for trapezius muscle pain are:

  • Supraclavicular fossa (upper part of this region).
  • Upper medial border of the scapula.

The main aim of the treatment is to deliver anesthesia, anti-inflammatory drugs, and steroids. This will lead to a decrease in pain, inflammation, and swelling associated with this condition. However, these injections also provide temporary relief from muscle tension but they should not be used as a regular treatment option. In addition, these injections may produce side effects such as local nerve damage or allergic reactions, etc. Hence it is advised that they must be done by trained professionals only rather than self-injecting at home under any circumstances.
