What is Myofascial Pain Syndrome?
Myofascial pain syndrome is a chronic condition affecting the muscles and their surrounding connective tissue, known as the fascia. It is characterised by the presence of trigger points — hypersensitive spots within a taut band of muscle that cause pain when pressed.
Trigger points can produce localised pain at the affected site or refer pain to a distant area of the body. A trigger point in the upper back may cause headaches. A knot in the lower back may send pain down the leg. This referred pain pattern is a key reason MPS is frequently misdiagnosed or confused with conditions such as a slipped disc, arthritis, or fibromyalgia.
MPS is common among Singapore’s working population, particularly those who spend long hours at a desk or in fixed postures. According to a review published in Regional Anesthesia (Han & Harrison, 1997), MPS may account for 30 to 85 percent of patients presenting to pain clinics, making it one of the most prevalent musculoskeletal pain conditions in clinical practice.
What Causes Myofascial Pain Syndrome?
MPS develops when muscle fibres are repeatedly strained, overloaded, or kept in a shortened position for too long. Several factors can trigger this process.
| Causes | How It Contributes |
|---|---|
| Postural strain | Long hours at a desk, extended screen time, and looking down at a phone place sustained load on the neck and shoulder muscles. Over time, this creates the conditions for trigger points to form. Particularly common in Singapore’s office-working population. |
| Repetitive movement | Repeated use of the same muscle groups in work or sport — especially with poor technique or insufficient recovery — overloads the muscle fibres and promotes trigger point development. |
| Acute muscle injury | A sudden twist, sports collision, or road traffic accident can directly activate trigger points in the affected area, which may persist long after the initial injury has healed. |
| Chronic stress and tension | Sustained emotional stress causes the body to hold muscles in a contracted state for extended periods. This impairs blood flow and allows pain-inducing substances to accumulate at the trigger point. |
| Nutritional deficiencies | Low levels of vitamin D or iron have been associated with increased muscle pain and a greater susceptibility to MPS. |
| Underlying medical conditions | Thyroid disorders, sleep disturbance, and certain systemic conditions can lower the threshold at which trigger points become active or prevent existing trigger points from resolving. |
What Are the Symptoms of Myofascial Pain Syndrome?
The symptoms of MPS are centred on muscle pain and tenderness. They vary in intensity between individuals and may fluctuate with activity, posture, and stress levels.
Important: MPS symptoms can overlap with other conditions. A thorough clinical assessment is always needed to confirm the diagnosis and rule out other causes.
How Is Myofascial Pain Syndrome Diagnosed?
MPS is a clinical diagnosis. There are no blood tests or imaging studies that definitively confirm it. Diagnosis is based on a detailed patient history and physical examination.
During the consultation, your pain specialist will review the nature, location, and behaviour of your pain, including where it spreads and what provokes it. A physical examination follows, during which the specialist palpates the muscles to locate taut bands and trigger points. Pressure on an active trigger point will typically reproduce the pain pattern you have been experiencing.
Imaging such as MRI or ultrasound may be ordered to exclude coexisting structural conditions — such as a slipped disc or nerve compression — that could be contributing to your symptoms.
The Painostic® Approach to Myofascial Pain Syndrome
At Singapore Paincare, myofascial pain syndrome is assessed using the Painostic® methodology — a proprietary diagnostic framework developed by Dr. Bernard Lee Mun Kam over more than 20 years of clinical practice.
Painostic® applies three structured clinical protocols, ensuring that treatment is directed at the true source of pain rather than the site where it is felt.
Diagnostic Formulation
The specialist differentiates between the mechanical and functional drivers of your pain, identifies the structures generating symptoms, and maps the referred pain pathways relevant to your case.
Injection Roadmap
A personalised, evidence-based treatment sequence is established, combining minimally invasive procedures, physiotherapy, and medication in the most effective order. For MPS, this typically begins with Myofascial Block or Coreflex Injections to break the trigger point cycle, followed by rehabilitation to correct the posture and movement patterns that allowed trigger points to develop.
Injection Technique
recision of delivery is established for each interventional procedure — optimal needle depth and target site — ensuring medication reaches the exact anatomical structure involved. This reduces the number of procedures required and supports longer-lasting relief.
What Are the Treament Options for Pain Syndrome in Singapore?
Myofascial pain syndrome treatment is most effective when it addresses both the trigger points and the underlying factors that caused them to develop. A structured, multidisciplinary approach produces the most sustained outcomes.
Conservative Treatment
- Physiotherapy — A programme of stretching, postural correction, and progressive strengthening helps release taut muscles, correct the imbalances that created trigger points, and reduce the risk of recurrence. Manual therapy and dry needling can also help deactivate trigger points directly.
- Heat therapy — Applied to the affected muscle, heat relaxes tissue, improves local blood flow, and prepares the muscle for stretching and rehabilitation.
- Postural and ergonomic correction — Addressing seated posture, workstation setup, and movement habits reduces the sustained muscle load that triggers MPS, particularly in desk-based patients.
- Cognitive Behavioural Therapy (CBT) — When stress or psychological factors are amplifying pain, CBT supports patients in modifying the thought and behaviour patterns that perpetuate the pain cycle.
- Medications — Medication supports treatment by reducing pain sufficiently for physical therapy to be effective. Depending on the presentation, your specialist may prescribe anti-inflammatory medications (NSAIDs) to ease early inflammation, muscle relaxants to interrupt the contraction cycle, low-dose antidepressants such as amitriptyline for pain modulation and sleep, or nerve stabilisers such as gabapentin or pregabalin for heightened pain sensitivity. Medication does not resolve the underlying trigger points on its own and is used alongside other treatment modalities.
When Should You See a Pain Specialist for Myofascial Syndrome?
Many people try to manage muscle pain on their own, and mild episodes often do settle with rest and gentle stretching. However, you should seek professional assessment if:
- your pain has lasted more than two to three weeks without improving; the pain spreads to other areas or follows an unusual pattern;
- you notice weakness, tingling, or numbness in the affected limb;
- the pain is interfering with your work, sleep, or daily activities; or standard physiotherapy has not produced meaningful improvement after six to eight weeks.
Early assessment helps prevent trigger points from becoming deeply embedded and difficult to treat. It also rules out other conditions that may require different management.
A Message About Myofascial Syndrome from Our Pain Specialist
Myofascial pain syndrome is one of the most frequently missed causes of chronic pain we see in clinical practice. Many patients arrive having been told their scans are normal, or having had their symptoms attributed to a different condition entirely.
The challenge with MPS is that referred pain travels. A trigger point in one location produces pain somewhere else — and without a systematic examination of the muscle system as a whole, that connection is easily missed.
With accurate diagnosis and the right treatment sequence, MPS responds well. Our Painostic® approach is designed to find the true source of your pain and build a plan that addresses it directly.
