Muscle knots, or myofascial trigger points, are small, bump-like areas of muscle that can be painful and tender to the touch. They are caused by chronic myofascial pain, which is felt in particularly sensitive trigger points in the body. While they are not air bubbles, they are often described as feeling like small irritating bubbles. When this kind of pain doesn't go away, the muscle can swell and harden into a bump or knot.

What You'll Learn
Muscle knots are not air bubbles but irritated trigger points
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. They are called myofascial trigger points because they develop when a muscle is irritated by a new or more strenuous-than-usual repetitive motion. For example, if you suddenly add running to your daily routine, you may notice knots in your calves as they adjust to this new movement. Similarly, hunching over a computer all day can cause knots to develop in your upper back and shoulders.
Sitting for prolonged periods can also cause muscle knots to form, as the muscles tighten and form knots, further compressing the surrounding muscles and leading to pain. In addition, vitamin deficiencies, prolonged bad posture, and stress can also predispose individuals to developing trigger-point trauma. When left untreated, muscle knots can result in further complications such as persistent pain and decreased flexibility.
There are various treatments available for muscle knots, ranging from home remedies to professional therapies. Home treatments include gentle stretching, applying warm or cold pads, and using a foam roller or handheld massage tools to apply pressure to the trigger points. If home remedies do not provide relief, professional treatments such as dry needling, electrical stimulation, manual therapy, and therapeutic massage may be considered.

They are caused by chronic myofascial pain
Muscle knots, or myofascial trigger points, are small, bump-like areas of muscle that can be painful. They are not air bubbles, but rather are caused by chronic myofascial pain. This pain is felt in particularly sensitive "trigger points" in the body, which are hyperirritable nodules of muscle that can cause chronic pain, decreased range of motion, referred pain, and autonomic dysfunction. When this kind of pain doesn't go away, the muscle can swell and harden into a bump or "knot". While there is no scientific consensus on why these knots form, they tend to show up after a muscle injury or strain due to repetitive motions. They often occur in the shoulders, back, or neck.
One theory is that the fibres that make up muscle tissue contract in response to extra calcium in the area. When a muscle gets damaged, even slightly, it can cause inflammation in the bands of muscle and the fascial layer above. This clump of inflamed tissue is a myofascial trigger point. The little lumps are typically tender to the touch and can limit range of motion or lead to pain during various movements. Myofascial trigger points tend to develop when a muscle is irritated by a new or more strenuous-than-usual repetitive motion. For example, if you introduce a new movement pattern to your daily workout, you may notice some knots in the muscles that are being worked in a new way.
There are a variety of treatments available to release the tight nodules of muscle and restore proper function. Home remedies include applying warm or cold pads, self-massage techniques, and stretching. If home remedies do not reduce the symptoms of muscle knots, professional treatments are available, such as cold laser therapy, dry needling, electrical stimulation, manual therapy, and therapeutic massage. The goal of physical therapy for muscle knots is to manage the intense pain and prevent the issue from recurring. A physical therapist will advise on exercises to stretch and strengthen the muscles in the affected area.

They can be treated with physical therapy
Muscle knots, or myofascial trigger points, are small, tender lumps or nodules of muscle that can be painful. They are often caused by chronic myofascial pain, which is felt in "trigger points" in the body. When this pain doesn't subside, the muscle can swell and harden into a bump or "knot". While there is no scientific consensus on why these knots form, they tend to appear after a muscle injury or strain due to repetitive motions. They are also associated with stress, vitamin deficiencies, and poor posture.
Muscle knots can be treated with physical therapy, which aims to manage pain and prevent recurrence. Physical therapists will develop an individualised treatment plan, which may include exercises and lifestyle modifications. For example, physical therapists may recommend stretching exercises to engage the muscle area with the knot, making the muscle longer and releasing tension. They may also recommend the application of ice or heat to the affected area. Generally, ice is used for acute injuries or newer muscle knots, as it can numb the pain, while heat is used for chronic or longstanding injuries to relax and loosen stiff muscles.
In addition to stretching and ice/heat therapy, physical therapists may also recommend dry needling, which involves inserting small, thin needles into the trigger point to bring blood flow to the area of discomfort and release the muscle knot. This technique may be combined with electrical stimulation, where electrodes are placed across the affected muscle to cause rapid contractions and release the knot.
Physical therapists may also recommend manual therapy, where the 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, can also be used to treat muscle knots.

They can be relieved with self-massage techniques
Muscle knots, or myofascial trigger points, are small, tender bump-like areas of muscle that can be painful. They are often caused by chronic myofascial pain and can develop anywhere on the body where muscle or fascia is present, especially in the shoulders, back, or neck.
While there is no scientific consensus on why these knots form, they tend to show up after a muscle injury or strain due to repetitive motions. One theory suggests that the fibres that make up muscle tissue contract in response to extra calcium in the area. Another theory suggests that stress and vitamin deficiencies can cause trigger-point trauma, leading to muscle knots.
Self-massage techniques can be an effective way to relieve muscle knots. Here are some tips for self-massage:
- Locate the muscle knot.
- Apply gentle to moderate pressure in circular motions with your fingertips for a few minutes.
- If the knot is too tender to massage directly, apply pressure to a nearby point and work your way towards it.
- For muscle knots that are hard to reach, try using a tool such as a trigger point cane or a Thai self-massage technique.
- Combine self-massage with heat therapy by applying a heat pad or hot water bottle to the area for 10-15 minutes to help relax the muscle and reduce pain.
- Try using a foam roller to apply static compression to the trigger points, which may help improve muscle function.
- Incorporate stretching into your routine to loosen the knots and improve overall flexibility.
- Consider taking over-the-counter anti-inflammatory medication to reduce swelling and provide pain relief.
Regular self-massage and the use of these techniques can help identify and treat muscle knots early on, reducing their impact on your quality of life and physical ability.

They can be caused by stress and tension
Muscle knots are small, bump-like areas of muscle that can be painful and tender to the touch. They are also known as myofascial trigger points and can cause chronic pain and affect a person's range of motion. While there is no scientific consensus on why these knots form, they are believed to be caused by chronic myofascial pain, which is felt in particularly sensitive "trigger points" in the body. When this kind of pain doesn't go away, the muscle can swell and harden into a bump or "knot".
One theory suggests that muscle knots are caused by stress and tension. Some research indicates that individuals who experience more stress in their lives may clench their muscles frequently, leading to the formation of tight spots or knots. Additionally, maintaining a sedentary lifestyle, such as sitting in front of a computer for extended periods, can contribute to muscle knots. The act of holding one position for hours places stress on the muscles, leading to the development of knots.
Sitting for prolonged periods can cause muscles to tighten and form knots, further compressing the surrounding muscles and resulting in pain. This is particularly common in individuals with desk jobs or those who spend a significant amount of time in front of a computer. The stress and tension in the neck and shoulder areas can lead to the formation of muscle knots in these regions.
Furthermore, stress can indirectly contribute to muscle knots by affecting an individual's posture. Prolonged periods of stress can lead to slouching or hunching, which in turn causes muscle tension and increases the likelihood of muscle knots. Engaging in relaxation techniques, such as meditation or gentle yoga, can help reduce stress levels and, consequently, decrease the likelihood of muscle knots.
While the relationship between stress and muscle knots is not yet fully understood, it is clear that stress can be a contributing factor. Managing stress through relaxation techniques and maintaining a healthy lifestyle that includes regular physical activity can help reduce the occurrence of muscle knots.
