Trapezius Strain: Causes, and Treatments for Trapezius Muscle Pain

Trapezius Strain: Causes, Symptoms, and Effective Home Remedies to Relieve Pain

Trapezius strain happens when muscles in your upper back or neck get stretched, pulled, or torn. Your trapezius muscles are located on either side of your spine and start from the middle of your back and reach up to the top of your neck. Your trapezius (sometimes called “traps”) connect to your shoulder blade and support the weight of your arm.

Strained trapezius muscle can happen by sudden jerking movements, lifting heavy items, not warming up before exercising, or playing certain sports. When trapezius muscles tear, get strained, or are injured, the symptroms will be sharp pain in your upper middle back and possibly your neck (trapezius pain). This can result in pain when moving your arms, throwing objects, or trying to work with your arms above your head. You may also suffer from swollen trapezius if the strain or muscle tear has been severe.

Treating pulled, torn, and painful trapezius muscle usually involves resting the strained muscle and applying ice or heat. After the initial trapezius strain and when the muscle begins to heal, massaging pain-relieving essential oils and exercising to strengthen your back muscles can help to speed up recovery time.

What is Trapezius Strain?

Trapezius strains are muscle injuries to the large muscles on either side of your upper spine. Doctors from the Mayo Clinic say that muscle strains occur when muscles or tendons stretch too much or tear completely.1

Because your trapezius muscle controls and supports your arm and shoulder movements, strains to the trapezius are very common. The sore trapezius muscles can make it difficult to turn your head or move your neck without pain. You could also find that if you are under stress, your “traps” tighten and it could feel like you have strained your trapezius muscles.

Symptoms of Trapezius Strain and Trapezius Muscle Pain

Usually, a tight and sore upper back is the most common symptom of inflamed or strained trapezius muscles. The tension in your upper back can cause a lot of pain and discomfort and can negatively impact on your daily activities.

Doctors from the Mayo Clinic say that muscle strains cause swelling and muscle spasms and may affect the range of motion in your left arm or right arm, depending on which trapezius muscle was strained.2 Depending which part of the trapezius muscles was strained, you might have an aching burning feeling in the back of your neck from your skull to your shoulder blades.

The area around the shoulder could become very tender to touch and feel like you have knots in your shoulders due to tension in the muscles.

Dr. William Blahd on WebMD says that muscle strain can also cause redness and bruising under the skin. You might also have neck, back, and shoulder pain even when resting. In cases of severe trapezius tears, you might not be able to use your arm muscles at all.3

Causes of Trapezius Strain

Let’s look at the main causes of trapezius strains and tears. Knowing what can injure the muscles at the top of your back between your shoulder blades can also help you know how to prevent suffering a trapezius muscle strain.

Pulled or strained shoulder muscle

Pulling or straining one of your shoulder muscles can also strain in your trapezius muscles. This can cause acute pain in your left or right shoulder, and your arm may be painful to move. Doctors from the Mayo Clinic say that falling, throwing, or lifting heavy objects can cause pulled muscles.4

Suffering a traumatic injury to your back or shoulder can also result in a serious trapezius strain and pain. The Journal of Neurology reported that injuries like whiplash can cause damage to one or both shoulders. In some cases, the nerves around the trapezius muscles can become so damaged that it causes permanent injury.5

Repetitive strain injury

One of the most common reasons for developing symptoms of trapezius muscle pain is due to repetitive actions. This often occurs if you have to sit for long periods of time at a desk or computer. The result of repetitive strain is overuse of the trapezius muscles that can cause inflammation, knots in your shoulder, and chronic pain.

The Scandinavian Journal of Rehabilitation Medicine reported that repetitive light work can cause musculoskeletal discomfort and pain. This can especially affect the neck and shoulder areas and especially affect the trapezius muscles.6

Carrying heavy items

You can easily pull trapezius muscles and cause upper back pain if you carry heavy items in an awkward position. You could also tear or injure your “traps” if you don’t lift heavy items properly.

Researchers from the University of Rochester say that if ligaments that hold the muscles in the shoulder and arms are strained beyond their normal limit, this can result in tearing muscles and cause pain. The pain could be acute from an injury and cause sharp, stabbing pains in the shoulder muscle. Or, if you frequently carry heavy items, you could weaken the trapezius and put yourself at more risk of damaging your shoulder.7

Not warming up properly

Failing to warm up properly before exercising can result in a trapezius injury. If muscles and ligaments are put under too much pressure without warming up, you can easily tear trapezius muscles.

Dr. Linda Vorvick on MedlinePlus says that muscle strain is often caused by improperly warming up before physical activity. The result can be a significant tear to your trapezius, rhomboid, or latissimus dorsi muscles.8

Age can also affect the flexibility and strength of your muscles and ligaments. Therefore, if you are an older person, light stretching and gentle exercising in the mornings can help warm up muscle groups and prevent unnecessary strains and muscle pain.

Playing sports

Certain sports that involve throwing, rowing, or hitting with a bat can strain and tear trapezius muscles. Muscle strain of the trapezius can happen without warning if you throw an object with a forceful, jerking motion.

For example, the American Academy of Orthopedic Surgeons says that overhand throwing can cause trapezius muscle injury and result in weakness of the shoulder. Muscles in the upper back can be damaged by throwing incorrectly or the muscle strain can happen gradually through overuse.9

Poor posture

Poor posture when sitting or standing can result in trapezius muscle strain that causes tension, stiffness, and pain in the upper middle back and neck.

According to doctors from the National Health Service (NHS), common bad posture habits that result in trapezius strain include slouching in a chair, cradling your phone between your shoulders and ear, standing with rounded shoulders, and leaning on one leg.10

If you sit at a desk all day, then sitting properly is important to prevent trapezius pain and tension in your upper back and shoulders. Doctors from the NHS say that sitting for long periods can cause a flat back that leads to muscle imbalances. This puts more strain on your trapezius and other upper back and neck muscles.

Doctors recommend taking steps to correct your posture to help ease tension in your back and relieve the symptoms of trapezius strain.


When you are under stress, your trapezius muscles are usually the first ones to bother you. Stress causes muscle tension and can even increase your risk of pulling or damaging your muscles, including your trapezius.

According to the Workplace Health and Safety Office of the Queensland Government, there is a proven link between stress and muscle strain. Stress creates many physical and mental responses that can increase symptoms of muscle pain and strain.11

If you find that stress is causing your back muscles to become sore and tense, then why not try some of my natural remedies for getting rid of anxiety?


Holding a baby during breastfeeding can put extra strain on your trapezius and cause knots in your shoulder muscles. There are a number of factors that cause trapezius strain while feeding a baby. First, holding your baby for a long time can strain your upper back muscles. Second, keeping your head or neck in a fixed position can strain the trapezius in your neck and give you a stiff neck.

You can avoid straining your trapezius while breastfeeding by laying down on your side if possible or sitting with a pillow on your lap to rest your baby.

Effective Home Remedies to Treat Trapezius Strain and Trapezius Pain

With proper care at home, you can easily treat symptoms of trapezius strain. Here are some of the most effective ways to heal strained and torn trapezius muscles to get rid of trapezius pain.


As soon as possible after tearing, straining, or pulling a trapezius muscle, put ice on it to prevent swelling and inflammation. An ice pack helps to numb the pain and also prevent nerve irritation causing discomfort.

According to Dr. Linda Vorvick on MedlinePlus, you should apply ice immediately to a torn trapezius muscle to reduce swelling. This will also reduce blood flow to the damaged muscles and prevent bruising.8

How to apply ice to strained and sore trapezius muscle

To help heal a pulled trapezius quickly using an ice pack, this is what you should do:

  1. Put crushed ice cubes in a sealable plastic bag and wrap in a clean towel (ice should never be placed directly on the skin).
  2. Hold the ice pack to the strained trapezius for 10-15 minutes to relieve trapezius muscle pain.
  3. Apply every hour for the first day and then every 3-4 hours on the second day.

On the third day, if you still have trapezius pain you should apply heat to continue the healing process.


A combination of Rest, Ice, Compression, and Elevation (or, the RICE method) can help to alleviate the pain of damaged muscles in your upper back. RICE will also help to prevent further injury to your trapezius muscles.

Dr. William Shiel on eMedicineNet says that the RICE method can help heal the strained muscles and boost the healing time of injured upper back muscles.12

How to use the RICE method to heal muscle strain:

  1. Rest the strained trapezius muscle by avoiding any activity that puts a strain on shoulder muscle.
  2. Ice the sore trapezius muscle between your shoulders by making a cold pack.
  3. Compress the affected muscles with an elastic bandage to restrict movement and reduce swelling.
  4. Elevate your body as much as possible by sitting up so that your shoulders are always above the level of your heart.


If you have severe pain in your trapezius muscles from a muscle strain or muscle tension, then applying a moist heat pack can relieve shoulder pain. Heat helps to increase blood flow to the affected area to promote soft tissue healing in your upper back.

According to Dr. William Blahd on WebMD, heat can be applied when swelling has gone down. Heat helps to boost the healing process and ease the pain in many types of muscle sprains and pulls.3

How to Use:

To reduce the healing time of pulled trapezius muscles and ease muscle tension using a heat pack, this is what you should do:

  1. Fill a clean sock or small pouch with rice and tie it shut.
  2. Place the rice-filled pack in a microwave and heat on full power for 2 minutes.
  3. Make a moist heat pack by dipping a washcloth in hot water and wrapping the heat pack in the dampened washcloth.
  4. Apply the heat pack to the pulled trapezius for 10-15 minutes every 3 or 4 hours.
  5. Use every day until all trapezius pain and muscle soreness from your shoulder and neck has gone for good.

Epsom salt bath to relieve trapezius muscle pain

One way to relax tense muscles and also relax your mind to ease muscle tension is to take a warm bath of Epsom salt.

Dr. Carol DerSarkissian on WebMD says that an Epsom salt bath can help to heal a pulled muscle and ease many aches and pains. It is thought that magnesium and sulfate from the salts penetrate the skin and help relax stiff muscles.13

How to use Epsom salts for muscle repair:

To make a healing bath with Epsom salt to get rid of trapezius muscle pain and repair damaged trapezius, this is what you should do:

  1. Fill your bathtub with very warm (but not hot) water and add 1 to 2 cups Epsom salts.
  2. Soak in the bath water for 20 minutes to allow the salts and minerals ease your muscle tension.
  3. Rinse off in the shower and dry yourself.
  4. Take the bath up to three times per week until your sore trapezius muscles are healed and are no longer sore.

Massage to relieve sore trapezius muscle

A massage with essential oils can help get a knot out of your shoulder muscles and relieve trapezius pain. There are many essential oils with pain relieving properties that are great for getting rid of soreness from strained muscles. Also, the massage technique improves blood flow to the pulled trapezius to help boost healing time.

A study in the journal Current Reviews in Musculoskeletal Medicine reported that massage can help repair damaged muscles quicker. It was found that massaging muscles for 10 minutes after strenuous exercising helped to reduce pain, soreness, and inflammation.14

How to use massage for strained trapezius muscle

You can easily make your own pain-relieving massage oil that you or your partner can rub into sore muscles in between your shoulder blades. This massage oil for sore muscle includes relaxing essential oils. This is what you should do:

  1. Mix 10-12 drops of peppermint oil, rosemary oil, or lavender oil with 1 oz. carrier oil such as sweet almond oil.
  2. Apply a little of the massage oil remedy to your sore trapezius muscle in your upper back and neck area and gently massage in circular movements.
  3. Apply the massage oil 2 times a day making sure that it all gets absorbed into your skin.
  4. Use every day to relieve trapezius muscle stiffness and knots and continue until you no longer have muscle pain.

Improve posture

Improving your posture is important not to just prevent trapezius strain, but also help speed up the healing process.

According to a sports injury clinic, good posture helps to keep muscles in balance. This prevents some muscles being shorter than others and prevents back pain, especially lower back pain.15

When sitting, your head should be upright with your shoulder back. You should be able to put your hand through the gap at your lower back.

When standing, good posture involves standing with your knees straight and your feet at shoulder width.

Easy Exercises to Heal Trapezius Strain and Pain

To help trapezius strains heal quicker and prevent them recurring, there are many effective exercises to strengthen your back and prevent upper back pain.

Here are 5 easy exercises to strengthen and flex your trapezius muscles you can do while sitting at your desk.

Shoulder blade pinches. Squeeze your shoulder blades together and hold for 10 seconds. Repeat 15 times.

Shoulder shrugs. Raise your shoulders in a shrugging motion, hold, then relax them. Repeat 15-20 times.

Neck stretches. Tilt your head to one side to try and touch your ear to your shoulder. Repeat with the other side and do the exercise 10 times.

Neck rotation. Move your head to one side so that your nose is parallel with your shoulders. Repeat the movement looking to the other direction. Do the exercise 15 times.

Neck rotation and stretching. Place your right hand on your head with your left arm at your side. Then gently pull your head towards your right shoulder. Rotate your head to look at your right hip. Repeat on the opposite side with your other hand. Repeat 10 times.

How Long Trapezius Strain Takes to Heal

Trapezius muscle strains should heal completely with proper rest and home remedies. Dr. William Shiel on eMedincineNet says that usually, most people recover completely from strained or pulled trapezius muscles. However, the length of time depends on the extent of the injury and if proper care was taken to let the muscle heal.16

How to Prevent Trapezius Strain

You can reduce your risk of pulling or straining trapezius muscles by not overusing your arm or shoulder muscles. Dr. William Shiel recommends stretching every day and always warming up before exercising to prevent muscle strain.17

Trapezius Strain and Trapezius Muscle Pain – When to See a Doctor

Although most trapezius muscle pain symptoms heal in time, some serious muscle injuries require examination by a medical professional. Dr. Carol DerSarkissian on WebMD recommends seeing a doctor for muscle strain in the following circumstances:18

  1. You have no strength in your arm.
  2. The injured area between your shoulder blades is cool, pale, or changes color.
  3. You have numbness and tingling in your back or arm.
  4. Pain in the neck or between your shoulders becomes increasingly severe and home remedies don’t relieve the discomfort.
  5. You need advice on how to go about your daily activities while the trapezius injury is healing.
