Muscle conditions in women
Your muscles move and steady your body. Autoimmune muscle disease shows up as true weakness, not just soreness.

Conditions that affect your muscles 8
Autoimmune and chronic conditions that can involve your muscles. Each guide covers early signs, labs to ask about, and when to see a doctor.
Dermatomyositis & myositis
AutoimmuneAutoimmune conditions in which the immune system inflames the muscles, causing weakness. Dermatomyositis also causes a distinctive rash.
Fatigue and chronic fatigue
ChronicOngoing exhaustion that limits daily life. It can come from a treatable cause, or it can be ME/CFS, a serious illness in which effort makes symptoms worse.
Myasthenia gravis
AutoimmuneAntibodies block the signal between nerves and muscles, causing weakness that gets worse with use and improves with rest.
Polymyalgia rheumatica
AutoimmuneAn immune-mediated inflammatory condition that causes pain and stiffness in the shoulders, neck, and hips, almost always after age 50.
Osteoarthritis
ChronicThe most common type of arthritis. The cartilage that cushions the ends of bones breaks down over time, causing pain and stiffness, most often in the knees, hips, hands, and spine.
Rheumatologic conditions
ChronicRheumatology covers conditions of the joints, muscles, bones, and connective tissue, and many of them are autoimmune. This overview explains how inflammatory joint pain differs from mechanical pain, and where to read about specific conditions.
Mixed connective tissue disease
AutoimmuneAn overlap condition with features of lupus, scleroderma, and myositis, marked by high levels of an antibody called anti-U1 RNP.
Chronic infections
ChronicOngoing symptoms that follow or are linked to an infection or exposure. Some links are well established, and others are still debated.
