Fibromyalgia (related)

Fibromyalgia is included here as autoimmune-related or suspected rather than a confirmed autoimmune disease, and it frequently occurs alongside autoimmune conditions such as lupus, rheumatoid arthritis, and Sjogren's, which is part of why it appears in this group. Research describes the primary driver as central sensitization, a change in how the nervous system processes pain signals that turns up sensitivity throughout the body, alongside possible contributions from peripheral nerve signaling and immune pathways still being studied.

It is understood to be the third most common musculoskeletal condition after lower back pain and osteoarthritis, and research estimates worldwide prevalence at roughly 2 to 3 percent of the population, though figures vary by diagnostic criteria used. It is substantially more common in women and most often diagnosed in the thirties.

Common signs

Widespread muscle and soft-tissue pain and tenderness, deep fatigue, unrefreshing sleep, and difficulty with memory and concentration (often called fibro fog). Many people also have headaches, digestive symptoms, and heightened sensitivity to touch, temperature, or sound.

This is a plain-language summary for orientation, not a diagnosis. Mechanisms are described as current understanding, not settled fact. Work with your own clinician for your care.
