[3] Additionally, systemic symptoms like weight loss, fatigue, and low-grade fever can manifest in individuals with myositis.

Myositis can arise from various causes, including injury, certain medications, infections, inherited muscle disorders, or autoimmune conditions.

The most common methods are physical examination, electromyography (EMG), magnetic resonance imaging (MRI), muscle biopsy, and blood tests.

[4] Magnetic resonance imaging can be useful in diagnosis,[9] allowing painless, non-invasive visualisation of any muscle wastage.

[4] Certain autoantibodies (antibodies that target muscle cells) can also be found in the blood, which can indicate that myositis is caused by an autoimmune disease.

It is a type of steroid and can cause a wide array of side effects, such as mood changes, increased hunger, trouble sleeping, etc.
