Excessive or unusual pain and discomfort felt in the muscles, tendons, ligaments and joints. Muscle pain can be chronic (persistent and long-lasting) or acute (sudden onset).  Other names for the condition are muscle aches, myofascial pain and myalgia

Possible causes

Muscle pain has a number of different causes.  Most commonly, muscle pain occurs shortly after an unaccustomed bout of exercise, and is simply the result of excessive loading and tension on the muscles, which develop microscopic tears as a result.  These tears heal within 72 hours, but pain and inflammation can accompany the healing process.  This is known as delayed onset of muscle soreness, or DOMS.  The pain will usually disappear within three days of the exercise bout.

Muscle pain at a very specific point may also occur as a result of a sudden tear in the muscle or tendon.  In this case, the pain will be localised in a very distinct point.  In both these cases, the pain develops suddenly.

In other instances, muscle pain is the result of conditions that are longer-lasting or chronic, and which may require medical consultation and diagnosis.  These conditions include:

    • Infections – flu, malaria, polio, roundworm, Lyme disease

    • Fibromyalgia – a condition in which there is body-wide pain and tender points in joints, muscles and tendons

    • Rhabdomyolysis – breakdown of muscle cells by the body

    • Polymyalgia rheumatica – an auto-immune disease causing muscle pain in the hip, shoulder or neck

    • Lupus – an auto-immune disease with chronic, long term inflammation causing muscle pain

Certain drugs can also cause muscle pain, including ACE inhibitors used for blood pressure treatments, statins used for cholesterol treatment and cocaine.


If the cause is easily identified, treatment consists of rest, limiting movements that cause pain, and possibly using ice, nutritional supplements and anti-inflammatories to reduce inflammation.

Supplements For Muscle Pain

Most muscle pain can be treated with adequate rest and nutrition / supplementation.

High doses of magnesium and calcium supplementation are helpful to reduce muscle cramps and to promote healthy muscle function and repair. Glucosamine may also be effective in reducing muscle soreness - glucosamine is critical for repairing and building connective tissue, which may be damaged at the ame time as a muscle tear happens.

Creatine can also be an effective way to ease muscle soreness. Creatine's main role in the body is helping boost energy production, but it can also help repair the small tears that occur in muscles as a result of exercise more quickly. A protein supplement may also reduce muscle soreness, as muscles need a ready source of protein to help themselves repair after exercise. Whey protein offers superior absorption, but is a milk product, so vegetarians and those with a lactose intolerance may prefer a soy- , rice- or pea-based protein.

Finally, supplementation with an omeag-3 supplement such as krill oil may be necessary. Krill oil has a proven anti-inflammatory effective which can reduce pressure on / swelling around injured muscles.

When to see a doctor

When muscle pain is persistent, lasting for longer than three days and does not have any obviously identifiable cause (an unaccustomed bout of training or sudden muscular injury, for example), a doctor’s opinion should be sought.  If there is any indication of infection, such as swelling, inflammation, or rash that accompanies the muscle pain, medical advice is recommended.  Finally, if the muscle pain is one of a collection of symptoms that may also indicate fever or infection (as with flu and malaria), consult a doctor for treatment.

What to expect at the doctor’s surgery

The focus will be on obtaining a history, including symptoms, location of the pain, history of activity, descriptions and patterns of the pain, identifying factors that improve or worsen the pain, and diagnostic tests to identify possible injury.

In some cases, further testing, including blood tests, may be called for.  These tests look at markers in the blood for muscle damage and possible causes.

Finally, the doctor may refer on to a physiotherapist for treatment, particularly in the case of a muscle tear or strain, or to another specialist for possible neurological testing.


This is dependent on the cause of the muscle pain.  For exercise/activity related muscle pain, rest, ice and limiting of movements causing pain are usually sufficient.   In cases where muscle pain is part of a broader spectrum of symptoms, treatment will be prescribed for the identified condition.

Treatment will often involve anti-inflammatory medication, as well as massage and physical therapy. Magnesium supplementation often reduce cramps.
