Understanding Trigger Points

Have you ever experienced a deep, persistent ache in your muscles that just won’t go away, no matter how much you stretch or massage the area? If so, you might have encountered a common yet often misunderstood phenomenon known as trigger points. In this blog, we’ll embark on a journey of understanding trigger points, shed light on what they are, how they form, and why they can be a source of discomfort and pain. Whether you’re a curious individual looking to understand your body better or someone seeking relief from nagging muscle tension, this exploration into the world of trigger points will provide valuable insights and guidance.

Understanding Trigger Points

What are trigger points?

Trigger points, also known as muscle knots, are small, irritable spots within a muscle that cause localized pain, referred pain, and muscle stiffness. These points are sensitive to pressure and can be felt as small, palpable nodules or tight bands of muscle tissue. Trigger points can develop in various muscles throughout the body, and are often associated with muscle overuse, injury, or tension.

Key Characteristics of Trigger Points

  • Localized Pain: Trigger points often cause pain or discomfort at the specific spot where they are located. This pain is usually described as a deep, aching, or throbbing sensation.
  • Referred Pain: Trigger points can refer pain to other areas of the body. For example, a trigger point in the shoulder muscle might cause pain in the arm or neck.
  • Muscle Stiffness: Muscles containing trigger points can become stiff and lose their normal range of motion. This can affect posture and mobility.
  • Palpable Nodules: Acupuncturists and other healthcare professionals can feel and identify trigger points by palpating the affected muscle. These nodules can be tender to the touch.

How do Trigger Points Form?

Trigger points form as a result of several factors, including muscle overuse, trauma, stress, and muscle imbalances. While we do not fully understand the exact mechanisms behind trigger point formation, several theories exist to explain their development. Here are some of the key factors involved in trigger point formation:

  • Muscle Overuse or Overloading: Excessive or repetitive use of a muscle can lead to the development of trigger points. This can occur in both athletes who engage in rigorous training and individuals who have repetitive job-related movements. Overloaded muscles can become fatigued and develop areas of increased muscle tension, which can eventually lead to trigger points.
  • Muscle Trauma: Acute injuries or microtrauma to muscle fibers can result in trigger points. Accidents, falls, or sudden muscle contractions can cause these injuries. When muscle fibers sustain damage, they may contract and form trigger points as a protective response.

  • Poor Posture: Maintaining improper posture over extended periods can place excessive stress on certain muscles. This prolonged muscle tension and imbalance can contribute to the formation of trigger points. For example, sitting at a desk with poor ergonomics for hours each day can lead to trigger points in the neck, shoulders, and upper back muscles.
  • Emotional Stress: Emotional stress and tension can manifest physically in the form of trigger points. Stress-induced muscle contractions can create areas of localized muscle tightness and discomfort. This is common in muscles that are prone to holding tension, such as the muscles of the neck and shoulders.
  • Muscle Imbalances: Muscle imbalances occur when certain muscles are overactive while their opposing muscles are weak or underactive. These imbalances can lead to abnormal movement patterns and increased stress on muscle groups, making them more susceptible to trigger point formation.
  • Nerve Irritation: Irritation or compression of nerves near a muscle can also contribute to the formation of trigger points. Nerve-related trigger points can result from conditions like herniated discs or entrapment of nerves, leading to muscle tension and discomfort.

Understanding the formation of trigger points can enhance the effectiveness of treatment and improve outcomes.

Location of Most Common Trigger Points

Trigger points can affect various muscles throughout the body, with some muscles experiencing trigger points more frequently than others. Here are some of the most common locations for trigger points:

  • Upper Trapezius: These trigger points are in the upper part of the trapezius muscle, which runs from the neck to the shoulder. They can cause neck and shoulder pain, as well as headaches.

  • Sternocleidomastoid: This muscle, located on the sides of the neck, can develop trigger points that cause pain in the neck, jaw, and behind the eye. They associated with tension headaches and neck pain.
  • Levator Scapulae: These trigger points lie at the back and side of the neck, causing neck and shoulder pain, along with referred pain down the arm.
  • Rhomboid Muscles: Trigger points in the rhomboid muscles, which lie between the shoulder blades, can cause upper back pain and discomfort.
  • Gluteus Medius and Minimus: Trigger points in the buttock muscles, specifically the gluteus medius and minimus, can cause hip pain and referred pain down the leg, mimicking sciatica.
  • Piriformis: Located in the buttocks near the hip joint, the piriformis muscle can develop trigger points that cause sciatic-like pain down the back of the leg, known as piriformis syndrome.
  • Lower Back: Trigger points in the lower back muscles, such as the erector spinae, can contribute to lower back pain and stiffness.

Treating Trigger Points At Home

Treating trigger points at home can be effective in managing muscle pain and discomfort. While self-care techniques may not replace professional treatment in some cases, they can provide relief and help prevent the recurrence of trigger points. Here are some at-home treatments for trigger points:

Stretching for trigger points
  1. Self Massage
  2. Heat Therapy
  3. Stretching
  4. Topical Analgesics / CBD Cream
  5. Proper Hydration
  6. Rest and Sleep
  7. Epsom Salt Baths
  8. Posture Correction
  9. Stress Management
  10. Exercise
  11. Self Awareness

While these at-home treatments can provide relief, it’s important to consult a healthcare professional if you experience severe or chronic trigger point pain, if the pain worsens, or if you have any concerns about your condition. A healthcare provider can offer a comprehensive assessment and recommend appropriate treatments.

Treatment With Acupuncture

Acupuncture, a traditional Chinese medicine practice, offers a unique approach to treating trigger points and the associated muscle pain. This therapy involves the strategic insertion of fine needles into specific points on the body. Here’s how acupuncture can effectively address trigger points:

Pain Relief

Acupuncture stimulates the release of endorphins, natural pain-relieving substances in the body. When acupuncture needles are inserted into trigger points or nearby areas, they help alleviate the perception of pain linked to trigger points.

Muscle Relaxation

The insertion of acupuncture needles induces a relaxation response in the muscles. This relaxation can aid in loosening tight muscle fibers commonly associated with trigger points, thereby reducing muscle tension and stiffness.

Enhanced Blood Flow

Acupuncture can improve blood circulation to the affected regions. This heightened blood flow delivers vital oxygen and nutrients to the muscle tissue and removes waste products, fostering a conducive environment for resolving trigger points.

Release of Muscle Knots

Acupuncture’s ability to promote muscle relaxation and diminish tightness aids in the release of myofascial trigger points. By breaking the cycle of pain and tension associated with these knots, acupuncture contributes to their resolution.

Anti-Inflammatory Effects

Acupuncture has demonstrated anti-inflammatory properties. Since inflammation can contribute to muscle pain and discomfort, acupuncture’s ability to reduce inflammation may be particularly advantageous for managing trigger points.

The effectiveness of acupuncture for trigger points can vary from person to person. Some individuals experience immediate relief from trigger point-related pain through acupuncture, while others may need more sessions to get relief. Acupuncture can be used as part of a comprehensive approach to trigger point management, combined with other therapies like physical therapy, massage, or specific stretching exercises.


In conclusion, gaining a comprehensive understanding of trigger points is essential for anyone seeking relief from the often debilitating pain and discomfort they can cause. These mysterious knots within our muscles can stem from various factors, including overuse, trauma, stress, and muscle imbalances. Acknowledging their presence and learning about their formation is the first step toward finding effective solutions.

By exploring the world of trigger points, we’ve unveiled the crucial role they play in our musculoskeletal health. Armed with this knowledge, we can take proactive steps to manage and alleviate the pain they inflict.
