Overview
Fibromyalgia is a long-term pain condition where the nervous system becomes overly sensitive, leading to widespread musculoskeletal pain. It often affects the back and other areas of the body, and it can also disturb sleep, mood, and energy levels. Unlike joint damage or nerve compression, the pain is not explained by a single structural problem on imaging. Because the pain and fatigue cycle can reinforce each other, symptoms may feel persistent or fluctuating over time.
Symptoms
People with fibromyalgia commonly notice widespread aching or burning pain on both sides of the body and often in the back, neck, shoulders, hips, and legs. Stiffness, tenderness, and fatigue are frequent, and many patients report non-restorative sleep or waking up feeling unrefreshed. Concentration problems, headaches, and heightened sensitivity to touch, cold, or pressure can also occur. Symptoms often flare after stress, poor sleep, overexertion, or periods of inactivity.
Causes
Fibromyalgia develops when the brain and spinal cord process pain signals differently, amplifying normal sensory input into pain. This may involve altered pain modulation, changes in sleep-related brain activity, and increased stress-related inflammatory signaling. In many people, symptoms begin after a trigger such as physical stress, illness, trauma, or prolonged periods of poor sleep. The exact cause varies, but the result is a persistent "pain sensitivity" state.
Risk Factors
Fibromyalgia is more common in women and often starts in early to middle adulthood, though it can occur at any age. A personal or family history of fibromyalgia or other chronic pain conditions increases risk, and mood conditions such as anxiety or depression may also coexist. Sleep problems, high stress, and a history of trauma or prolonged illness can raise the likelihood of developing symptoms. Some infections or events that disrupt sleep and recovery may act as triggers.
Prevention
While fibromyalgia cannot always be prevented, you can often reduce symptom flares by protecting sleep and keeping activity levels consistent. Regular low-impact conditioning, pacing (avoiding boom-and-bust cycles), and gradual strengthening can help your nervous system tolerate daily demands better. Managing stress through evidence-based strategies and treating comorbid conditions such as depression, anxiety, or sleep disorders may lower flare frequency. Avoiding prolonged inactivity and maintaining healthy body weight can also support overall function.
How the Diagnosis Is Evaluated
Clinicians usually diagnose fibromyalgia based on a detailed history of widespread pain and symptom patterns, along with a focused physical examination. Standardized criteria, such as pain distribution and symptom severity scales, are commonly used to support the diagnosis. Because similar symptoms can come from other conditions, doctors often order targeted blood tests (for example, to evaluate thyroid disease, inflammatory disorders, anemia, or vitamin deficiencies) when indicated. Imaging is typically not diagnostic for fibromyalgia and is reserved for evaluating specific red flags or alternative diagnoses.
Nonsurgical Treatment Options
Treatment focuses on reducing pain sensitivity, improving sleep quality, and restoring function with a personalized plan. Gradual aerobic exercise (such as walking, cycling, or swimming) and physical therapy can improve endurance and decrease pain over time when started slowly and progressed steadily. Cognitive behavioral therapy, mindfulness-based stress reduction, and other coping skills can help break the pain-stress-sleep cycle. Medications may be used to target nerve pain and sleep disruption, including options such as duloxetine or milnacipran (SNRIs) and pregabalin (an anticonvulsant), and sometimes low-dose tricyclic antidepressants like amitriptyline. For focal areas that behave like myofascial trigger points, clinicians may consider trigger point injections as an adjunct, while lifestyle measures remain the foundation.
When to Seek Medical Attention
Seek medical attention promptly if your pain is rapidly worsening, if you develop new weakness, trouble walking, or progressive numbness, or if symptoms follow an illness with fever. Get urgent evaluation if you have severe swelling, unexplained weight loss, bowel or bladder changes, or sudden loss of function. If fatigue and sleep problems become disabling, or if you feel unable to function at work or home, schedule an evaluation soon to confirm the diagnosis and rule out treatable alternatives.
Frequently Asked Questions
Fibromyalgia is a long-term condition in which the nervous system amplifies pain signals, causing widespread musculoskeletal pain and common fatigue and sleep problems.
Some people experience long-term improvement or remission of symptoms, but many have a fluctuating course that requires ongoing management.
It is diagnosed mainly from your history and symptom pattern using established criteria, along with an exam and targeted testing to rule out other conditions when appropriate.
Next Steps
If your pain is widespread and you also have fatigue and sleep disruption, consider scheduling a clinician visit to confirm the diagnosis and rule out other causes. Bring a symptom timeline, list of medications, and notes about flare triggers and sleep quality to help guide evaluation and an individualized treatment plan.
