What it is
Muscle pain (myalgia) describes pain originating from muscle tissue — experienced as aching, soreness, tenderness, or deep dull pain within one or more muscles.

- People describe a range of muscle pain experiences: deep, dull aching that worsens with use and persists at rest; sharp pain provoked by pressure on specific points; a generalised burning or heaviness that fluctuates with stress and weather; or stabbing pain that radiates from a trigger point to neighbouring areas. Many have adapted their activities significantly to avoid provocation of pain, which itself often leads to deconditioning and increased sensitivity.

Patterns of Muscle Pain
Myalgia (muscle pain) encompasses a spectrum from the familiar delayed onset muscle soreness (DOMS) following unaccustomed exercise, to the widespread, persistent muscle pain of fibromyalgia, to the acute diffuse myalgia of viral infection (influenza, COVID-19), to the proximal limb pain and weakness of inflammatory myopathy (polymyositis, dermatomyositis). Distribution, onset, character, and associated features guide differential diagnosis. Acute localised myalgia commonly reflects strain, overuse, or muscle contusion. Diffuse myalgia with systemic features (fever, fatigue) suggests viral or systemic illness. Persistent widespread myalgia with fatigue and sleep disturbance is characteristic of fibromyalgia. Medication-induced myopathy (particularly statins — in 5–10% of users) is an important and underrecognised cause. Proximal muscle weakness with pain raises concern for inflammatory myopathy.

The Evidence
Evidence context: Muscle Pain
What the evidence says about muscle pain — its causes, management options, and when professional assessment is essential.
Overall pictureHigh evidence base
Muscle pain is well-studied with clear management pathways
Myalgia has a broad range of causes — from exercise and viral illness to medication side effects and inflammatory conditions. Evidence supports targeted approaches depending on cause, with multidisciplinary care recommended for persistent or widespread presentations.
When to seek urgent assessmentSome muscle pain presentations require prompt professional evaluation and should not be self-managed.
Severe muscle pain with dark or cola-coloured urine may indicate rhabdomyolysis — a potential renal emergency requiring immediate care. Proximal muscle weakness with pain may suggest inflammatory myopathy. Muscle pain on statin therapy with elevated CK warrants dose review. Myalgia with fever, weight loss, or lymphadenopathy needs systemic assessment.
What the evidence supportsManagement strategies for muscle pain vary by cause, with strong evidence for several approaches.
Exercise-induced myalgia responds well to graduated activity and RICE principles. Fibromyalgia has the strongest evidence for aerobic exercise, CBT, and certain medications reviewed with a prescribing clinician. Viral myalgia is managed symptomatically. Physiotherapy and hydrotherapy benefit most persistent presentations.
Understanding the causesMuscle pain has many distinct causes that require different approaches — identifying the pattern matters.
Acute localised pain typically reflects strain or overuse. Diffuse myalgia with systemic features points toward viral or inflammatory illness. Persistent widespread pain with fatigue and sleep disturbance is characteristic of fibromyalgia. Statin-induced myopathy is a recognised and frequently underrecognised side effect affecting a meaningful proportion of users. Thyroid disorders and electrolyte imbalances are also common contributing factors.
Complementary approachesSeveral complementary options are used alongside conventional care for muscle pain, with varying evidence.
Magnesium supplementation may support muscle function, particularly where deficiency is present. CoQ10 is sometimes used for statin-related myalgia, though evidence remains mixed. Topical arnica and curcumin (turmeric) have limited but emerging evidence for localised muscle discomfort. Given that muscle pain can reflect inflammatory or medication-related causes, ruling these out with a qualified practitioner matters before relying on adjuncts alone.
Traditional approaches to muscle painMuscle pain has been addressed across traditional healing systems through manual therapy, heat, and herbal application.
Thai massage, Ayurvedic kizhi (herbal bolus poultice), and TCM tuina use manual tissue work and heat to address muscle tension and pain. Mahanarayan oil and medicated oils are used in Ayurvedic practice for deep muscle pain. Epsom salt baths are widely used; some proponents suggest transdermal magnesium absorption as a possible mechanism, though this remains unconfirmed and evidence is limited.
Safety considerationsSome common self-management choices for muscle pain carry risks worth understanding.
Long-term high-dose NSAID use for myalgia carries gastrointestinal and renal risks without addressing the underlying cause. Strenuous exercise during active inflammatory myopathy may worsen muscle damage. Anyone with persistent, worsening, or unexplained muscle pain should seek professional assessment before continuing or starting any management approach.
