Overview

Myositis
Myositis refers to inflammation of muscles involved in movement. It is a group of inflammatory muscle disorders rather than a single disease. Myositis may cause muscle weakness, fatigue, difficulty with activities such as walking or climbing stairs, and in some forms a characteristic skin rash. Polymyositis and dermatomyositis are examples of inflammatory myopathies. Some people can also develop difficulty swallowing or breathing when muscles involved in these functions are affected. Diagnosis and treatment depend on the particular type and underlying cause.
Boils
A boil is a painful, pus-filled lump caused by an infection involving a hair follicle and nearby skin tissue. It may start as a tender, swollen area and enlarge as pus builds up. Several nearby boils can join to form a carbuncle.

Diagnosis

Myositis
Evaluation usually begins with a medical history and physical examination focused on muscle strength and the pattern of weakness. Blood tests may identify elevated muscle enzymes or evidence of autoimmune activity. Imaging can help assess affected muscles, and electromyography may provide additional information about muscle function. In selected cases, a muscle biopsy is performed to identify the type of inflammatory muscle disorder. The combination of clinical findings, laboratory testing, imaging, and sometimes biopsy helps establish the diagnosis.
Boils
A healthcare professional can usually identify a boil by examining its appearance and asking about symptoms and previous episodes. A sample of fluid or pus may be cultured to identify the organism. Recurrent boils or signs of a wider infection may warrant further evaluation.

Prevention

Myositis
There is no established way to prevent all forms of myositis because autoimmune and genetic factors can play an important role. Avoiding unnecessary exposure to known muscle-injuring medicines and promptly addressing infections or other medical conditions may reduce some risks, but prevention depends on the underlying cause. For people who already have myositis, appropriate treatment, physical therapy, safe exercise, adequate rest, and monitoring for swallowing or breathing problems can help reduce complications and preserve function.
Boils
Regular handwashing, keeping skin clean, and keeping cuts clean and covered can reduce infection risk and spread. Avoid sharing towels, washcloths, or razors. Cover draining areas with a clean dressing and wash hands after contact. These measures reduce risk but cannot prevent every boil.

Risk Factors

Myositis
Risk varies according to the type of myositis and its cause. Factors that may be relevant include autoimmune disease, certain infections, previous muscle injury, and exposure to medicines associated with muscle inflammation or injury. The specific age, sex, and pattern of risk also differ among inflammatory muscle disorders. A history of progressive weakness, difficulty rising or climbing stairs, repeated falls, swallowing problems, or breathing difficulty warrants medical evaluation rather than assuming the symptoms are due to ordinary muscle fatigue.
Boils
Boils may be more likely with diabetes, conditions that weaken the immune system, certain skin conditions such as eczema, obesity, or close contact with someone who has boils. These factors affect susceptibility or exposure; a boil is not, by itself, evidence of poor personal hygiene.
