Myofascial trigger points are defined as “hyperirritable” nodules of muscle that can cause chronic pain, a decreased range of motion, referred pain, and autonomic dysfunction.
Muscle knots can develop almost anywhere on the body where muscle or fascia is present.
Places where muscle knots commonly occur include:
- calf muscles
- lower back
- mid back
Muscle knots feel like small, tender lumps or nodules. They
Symptoms of myofascial trigger points include:
- deep pain
- general numbness or tingling
- feelings of nerve pain
- a decreased range of motion
This symptom helps differentiate a trigger point from a tender point. A tender point is an area that hurts only when touched and only in the specific area pressed.
Unlike trigger points, the pain from tender points does not radiate to other muscles.
One of the
Tension and knots in the trapezius muscles often occur due to stress and poor posture.
Muscle knots can also cause additional symptoms, including:
Common causes of muscle knots include:
A person who spends a significant amount of time sitting at work may develop muscle knots due to staying in the same position for prolonged periods.
Doctors have identified several risk factors for people more likely to experience trigger points. These
Additionally, poor postural alignment due to cell phone use and improper sleeping and sitting positions
Treating myofascial trigger points often requires a
Evaluating why muscle knots might have occurred can help determine the best course of treatment.
For example, if muscle knots are due to prolonged sitting or a prior muscle injury, engaging in regular stretching breaks may help reduce muscle tension.
If muscle knots are due to poor posture, partaking in posture-correction exercises may improve symptoms.
People can also try:
Applying sustained pressure to muscle knots leads to an increase in blood flow, which in turn causes the release of muscle fiber tension. This is called myofascial release.
For this reason, self-massage techniques that apply pressure to myofascial trigger points may help increase a person’s range of motion and reduce pain.
To perform a self-massage, a person can place a tennis ball or foam roller between their back and the wall or floor, using the pressure from the ball to massage the trigger point.
If home remedies do not reduce the symptoms of muscle knots, professional treatments are available. The goal of these treatments is to release the tight nodules of muscle to relax the muscle and restore proper function.
Typically, a variety of treatments are used together in order to restore functionality and provide lasting relief.
- cold laser: also called low level light therapy, in which the trigger point is exposed to near-infrared light
- dry needling: in which a doctor inserts a thin needle into and around the trigger point to release the muscle knot
- electrical stimulation: in which an electrode is placed across the affected muscle to cause rapid contractions and release the knot
- manual therapy: in which a therapist assesses an individual’s posture and provides exercises and manipulations to realign and correct it
- therapeutic massage: including trigger point pressure release, passive rhythmic, and active rhythmic massage
- transcutaneous electrical nerve stimulation (TENS): in which low voltage electrical signals from a small device are applied to the skin
- pulsed ultrasound: in which sound waves are used to penetrate muscles
- therapeutic massage
- trigger point injections: in which a numbing agent or steroid is injected into the muscle knot
Muscle knots are often caused by poor posture and inactivity. Practicing good posture and engaging in regular physical activity may help prevent muscle knots.
Many knots develop from repeated muscle trauma, so a person may wish to engage in different activity types to prevent overuse of the same muscles. Activities might include swimming one day and walking the next, based on ability.
Additionally, myofascial trigger points are more common under conditions of psychological stress.
For this reason, taking steps to
A doctor or physical therapist can help ensure a person is practicing the right postures when exercising or working. Evaluating ways to practice better posture and form can help a person prevent muscle injuries and muscle knots.
Muscle knots or myofascial trigger points can often be treated with simple home remedies, self-massage, and stretching. However, some knots can cause chronic pain and disability, and interfere with a person’s everyday life and activities.
When this is the case, a person should see a doctor or physical therapist for treatment. Often, a multimodal approach using various techniques is most effective.
