What is Myositis?

Myositis is a rare condition causing muscle inflammation. In this chronic condition, the body's immune system misinterprets the muscle cells as intruders and targets them thus weakening and destroying them. It is a rare autoimmune condition that develops slowly over time and causes painful muscles.

Myositis is usually challenging to diagnose, and it has no cure. It can occasionally cause the skin to peel and break out in massive rashes. This condition, known as dermatomyositis, causes soreness and swelling in several muscle groups, including the arms, abdomen, and even the feet, as in the case of plantar fasciitis. To ensure effective medical care and treatment, it is advised to immediately visit a doctor as soon as an individual develops persistent muscular pain.


Different types of Myositis are based on the symptoms and the affected muscle location. They are:

  • Dermatomyositis
  • Inclusion-body Myositis
  • Juvenile Myositis
  • Polymyositis
  • Toxic Myositis


Although each myositis condition varies through its symptoms and treatment methods, all are characterized by persistent muscle inflammation. Typically, this inflammation causes muscle weakness and fatigue, frequent stumbling, swelling of the feet and legs, and discomfort in the muscles and joints. Early signs of Myositis in patients include:

  • Problem standing up from a seated position
  • Problem climbing stairs
  • Problem lifting the arms
  • Fatigue after standing or walking
  • Trouble swallowing or breathing
  • Frequent muscle pain
  • A red or purple-colored rash on the eyelids, elbows, knees, and knuckles

When to See A Doctor?

It's advisable to visit a doctor if someone exhibits any myositis symptoms. The doctor could identify the type of Myositis. However, if a patient notices any of the following symptoms frequently, they should seek medical attention immediately.


However, the exact cause of Myositis is still unknown. The signs and symptoms of an autoimmune disorder are still spurred on by your body's immune system attacking healthy tissues rather than defending them. Following are some of the conditions that may cause Myositis, according to researchers:

Risk Factors

The main risk factors of this disease include:

  • Inflammation
  • Weakness
  • Swelling


Most autoimmune diseases are complex, multifaceted conditions that have no simple solutions. Some complications may occur because of Myositis:

  • Antisynthetase syndrome
  • Calcinosis
  • Cancer-associated Myositis
  • Cardiovascular disease
  • Dysphagia
  • Infection
  • Interstitial Lung Disease
  • Overlapping autoimmune diseases
  • Rhabdomyolysis


Myositis cannot be prevented entirely. However, by making a few modifications to your lifestyle, you may control the symptoms:


Physical therapy is often advised by doctors together with medicines. Regular stretching exercises help maintain the range of motion in weakening arms and legs after the medications take action and stop muscular shortening.


To treat Myositis, it is essential to ensure the patient gets adequate sleep. Furthermore, minimizing activities and getting frequent breaks during the day are necessary.

Nutritious meal

A healthy diet helps to avoid and reduce the effects of the symptoms. Therefore, following a dietician-recommended diet plan is essential.

Reduce stress

Myositis patients may benefit from activities like yoga and meditation since managing stress is essential.


A physician may recommend multiple tests to determine if a patient has Myositis. Generally, these tests check to see if some enzymes are present, such as serum creatine kinase. Additionally, they might examine the body for myositis-specific antibodies, and Myositis tests include these.

Blood Tests

Blood Tests: The blood test results may show increased levels of enzymes such as creatine kinase. The enzymes might indicate muscular inflammation. It can also check for antibodies that can identify autoimmune diseases.


Electromyography: In this test, a small electrode is inserted via a needle into the muscle to record electrical impulses from the nerve endings that regulate the movement of your muscles. An unusual electrical activity pattern in muscles may result from Myositis. The exam could be uncomfortable even though it won't hurt too much.

Muscle biopsy

To check for symptoms of inflammation, a small sample of your muscle may be taken from the side of your thigh or calf. This is done under general anesthesia. Sometimes, if standard treatments are unsuccessful, you could require a second muscle biopsy. This is to check for the proteins found in inclusion body myositis.

Magnetic resonance imaging (MRI)

Magnetic resonance imaging (MRI): An MRI scan can pinpoint where the inflammation is. Occasionally, muscular damage can be seen by MRI scans as areas where fat has taken the place of muscle. An MRI scan uses magnets to peer into your body to determine what's happening. It might indicate bone problems and soft tissue damage to the muscles, ligaments, or nerves.


Myositis treatment may vary depending on what triggered the condition. However, the primary treatments are exercise and medicine. Medicine is used as the first line of defense against the disease. Patients get substantial doses the very first time they consume corticosteroids. These are given as injections or tablets and help to lessen disease symptoms by lowering muscle pain and inflammation. Inflammatory illnesses that cause Myositis are treated with drugs that inhibit the immune system. The medicines are

  • Azathioprine,
  • Prednisone,
  • Methotrexate.

There is no specific treatment for Myositis caused due to a viral infection, and if medications cause Myositis, It can only be treated by discontinuing the specific medicines. In most circumstances, if the medications mentioned above cannot treat Myositis, it leads to more severe cases requiring treatments like:


Antibodies called immunoglobulins are collected through blood donations. These can prevent immune system attacks on body tissue. People may experience some mild discomfort while getting this treatment.

Biological Therapy

Myositis is treated with biological treatments that block immune system targets that lead to inflammation. Even the most severe myositis cases could be effectively treated, but some patients may need to take medications for the rest of their lives to keep the condition in control.

Physiotherapy and Exercise

During a myositis flare-up, rest is essential. If you want to improve stamina and rebuild muscle strength, you need to engage in aerobic workouts that accelerate your heartbeat and help you breathe more strongly. Patients frequently receive individualized treatment plans from physiotherapists, and so do these exercises under their supervision. Never work out vigorously if you have Myositis. People with juvenile dermatomyositis need more demanding physical treatment to prevent permanently bending their knees and other joints.
