Fibromyalgia

Fibromyalgia is a chronic pain syndrome characterized by widespread musculoskeletal pain, fatigue, cognitive difficulties (“fibro fog”), and sleep disturbances. It is thought to result from central sensitization—heightened pain processing in the brain and spinal cord. While there is no cure, multimodal care significantly improves quality of life.

Causes & Risk Factors

• Central nervous system amplification of pain signals
• Neurotransmitter imbalances (serotonin, norepinephrine, dopamine)
• Autonomic dysfunction, HPA-axis dysregulation
• Genetics and family history of chronic pain disorders
• Triggers: infections, trauma, emotional stress, hormonal shifts
• Coexisting conditions: IBS, migraine, TMJ disorders, autoimmune disease

Symptoms

• Widespread pain lasting > 3 months in multiple body regions
• Fatigue, non-restorative sleep, morning stiffness
• Cognitive impairment: memory lapses, slow processing, word-finding issues
• Headaches, dizziness, tingling, temperature sensitivity
• IBS symptoms, bladder urgency, pelvic pain
• Anxiety, depression, or PTSD may coexist

Diagnosis

• Clinical diagnosis based on 2016 ACR criteria (Widespread Pain Index and Symptom Severity Scale)
• Rule out mimicking conditions: hypothyroidism, vitamin deficiencies, inflammatory arthritis
• Labs: CBC, CMP, TSH, vitamin D/B12, ESR/CRP if indicated
• Physical exam: tender points less emphasized; focus on overall symptom burden

Treatment & Management

Lifestyle Foundations

• Prioritize sleep hygiene (consistent schedule, dark room, limit caffeine)
• Low-impact exercise (walking, swimming, tai chi, yoga) improves pain over time
• Anti-inflammatory or Mediterranean-style diet; stabilize blood sugar
• Stress-reduction practices (mindfulness, deep breathing, pacing techniques)
• Heat therapy, gentle stretching, massage

Medications

• SNRIs (duloxetine, milnacipran) for pain and mood
• Anticonvulsants (pregabalin, gabapentin) for neuropathic pain
• Low-dose tricyclics (amitriptyline) for sleep/pain
• Avoid chronic opioids; consider tramadol only for refractory cases
• Treat comorbid conditions (migraine prophylaxis, IBS meds, mental health therapies)

Complementary Therapies

• Cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT)
• Acupuncture, trigger point injections, craniosacral therapy
• Occupational therapy for pacing and ergonomics

Living with Fibromyalgia

• Track pain, fatigue, mood, sleep, and triggers to identify patterns
• Break tasks into manageable steps and schedule rest breaks
• Communicate needs to family/employers; consider workplace accommodations
• Engage in peer support groups to reduce isolation
• Celebrate small victories—symptom management is a marathon

Complications

• Reduced work capacity or disability
• Mood disorders, social withdrawal, relationship strain
• Deconditioning if activity declines
• Increased healthcare costs without clear answers—advocacy is essential

Research & Future Directions

Scientists explore neuroimaging biomarkers, neuromodulation, small-fiber neuropathy links, and gut microbiome involvement.

Experimental & Emerging Treatments

• Transcranial Magnetic Stimulation (TMS) and transcranial direct current stimulation (tDCS) target brain regions to modulate pain perception.
• Vagus Nerve Stimulation (implanted or external) aims to reduce autonomic arousal and inflammation.
• Low-Dose Naltrexone (LDN) shows promise in small trials for pain and cognition by modulating microglia.
• Medical Cannabis & Cannabinoids: High-CBD formulations are being studied for analgesia and sleep, with variable regulatory status.
