M60-M63: Disorders of muscles

M62: Other disorders of muscle

The group range M62 represents a category of health conditions collectively referred to as "Other disorders of muscle." These disorders involve the muscles—soft tissues that help your body move—undergoing diverse and complex changes that adversely affect their normal functioning. Some conditions in this group might be caused due to genetic factors, metabolic issues, infections, or the immune system attacking the body's own tissues. Different disorders in this category may present in a variety of ways. Common symptoms may include muscle pain, weakness, stiffness, or cramps. While some conditions lead to progressive loss of muscle strength or function, others might have acute episodes of symptoms flaring up. These disorders can also be influenced by factors such as age, gender, environmental exposures, and individual health history. Depending on the specific condition, the effects could range from minor discomfort and reduction in physical activities, to severe disability. However, the progression and severity of these disorders can vary dramatically from person to person.
