Myositis: symptoms, treatment and causes

Myositis is called muscle inflammation, which is manifested by pain and muscle weakness.


  • Local myositis - inflammation in a restricted area of ​​the body.
  • Diffuse myositis - inflammation of a large area of ​​the muscle.
  • Polymyositis - the involvement of several muscle groups in the process.

Myositis also can be:

  • Acute.
  • Chronic. It can occur as a result of frequent occurrence of acute myositis( hypothermia) or chronic infections.

Causes of the disease

Depending on the symptoms of myositis, treatment is prescribed individually for each case. There are several reasons for the development of myositis:

  • Infectious diseases( influenza, angina).
  • Diabetes mellitus, gout.
  • Osteochondrosis.
  • Scoliosis.
  • Parasites inside the muscle fibers.
  • Subcooling.
  • Static muscle strain.
  • Bruises.
  • Long stay in uncomfortable position.
  • Joint disease.

Most often myositis occurs in:

  • Athletes
  • Drivers
  • Operators PC
  • Musicians( violinists, pianists).
  • All those who stay in an uncomfortable position for a long time.

Symptoms of the disease

The main symptoms of myositis:

  • Pain in inflamed muscles.
  • Swelling and redness.
  • Muscle atrophy( decrease in their volume).
  • Weakness of muscles.

In acute myositis, sudden pain occurs after hypothermia, an infectious disease, excessive tension or trauma. In the painful area, there is swelling and redness. The aching muscles become strained. Because of this, the limitation of movements in the joints is reduced. As a consequence, there is muscular dystrophy. In case of severe inflammation, body temperature may increase.

Acute myositis of infectious etiology is not characterized by such severe pains, and occurs due to infectious diseases.

As a result of damage to anaerobic microorganisms, streptococci and staphylococci, as a result of osteomyelitis or the result of purulent inflammation, purulent acute myositis occurs. It can be manifested by severe pain and purulent processes in the muscles. Such myositis can cause phlegmon, abscess and even necrosis( necrosis) of the muscle region.

Chronic myositis occurs after persistent acute myositis. Usually develops:

  • Cervical
  • Thoracic
  • Lumbar

Cervical myositis is manifested by dull muscular pain that can be given to the nape, shoulder girdle and area between the scapulae. In this case, the vertebrae of the cervical region usually retain mobility. But when stretching painful muscles, movements in the neck can be limited. With cervical myositis, the muscles of the larynx may be involved in the process, which makes it difficult for the patient to swallow.

pain in the neck Cervical myositis accompanies muscular pain in the neck

In chest myositis, intercostal muscles are involved in the inflammatory process. At the patient in connection with pains during the movement of the chest, there is shortness of breath.

Lumbar myositis is manifested by prolonged course and severe pain.

Myositis, which occurs as a result of parasitic diseases( toxoplasmosis, echinococcosis), is the result of an allergic reaction to the introduction of parasites into the body.

Diagnosis and treatment of myositis

To determine the correct treatment, the patient is examined and the presence of concomitant diseases is established. Diagnosis of myositis also includes a blood test for the presence of antibodies and electromyography.

In any case, the treatment of myositis is individual. As a result of the identified causes of myositis, the patient is prescribed a set of measures. It is useful for myositis to prescribe dry heat, physiotherapy procedures, massage of affected areas of the muscles with warming ointments or heated essential oil( lavender or marjoram oil can be used) and therapeutic gymnastics.

If myositis is caused by any infectious or parasitic diseases, the treatment of the underlying disease is prescribed. Apply for this analgesic, anti-inflammatory and other drugs in myositis.

In the case of supercooling or overstrain, rest, anesthesia, anti-inflammatory patches( Nanoplast forte) and ointments for myositis( Finalgon, Apizarthron, Nikoflex, etc.) are prescribed. A diet with inclusion of easily digestible proteins and the exclusion of acute and salty foods is also prescribed.

In severe form or purulent myositis, a patient may be prescribed plasmapheresis. In cases of infection, antibiotics are prescribed. If the disease is of an autoimmune nature, hormones are prescribed. In any case, the surgeon can tell you how to treat myositis. With purulent myositis, the surgeon opens the focus of infection and treats the patient in the surgical department.

To cure myositis non-steroidal anti-inflammatory drugs are prescribed:

  • Ketonal
  • Nurofen
  • Diclofenac
  • Naklofen

Drugs are taken orally or injected intramuscularly.
