When everything hurts and the fatigue does not pass with rest

The combination of diffuse pain throughout the body and extreme fatigue that does not improve with rest is one of the most challenging clinical presentations in medicine. Patients describe the sensation of "everything hurting", of waking up more tired than when they went to bed, of feeling that the entire body is inflamed — but all laboratory tests come back normal. This picture, when chronic, raises the hypothesis of fibromyalgia: a chronic generalized pain syndrome with sensitization of the central nervous system.

What makes fibromyalgia so complex is that it is not a simple diagnosis of exclusion — it is a real condition of dysregulated pain processing in the central nervous system. Medical acupuncture, especially low-frequency electroacupuncture, acts directly on the descending pain modulation pathways and on the autonomic nervous system, offering a therapeutic approach that addresses the central mechanism of the disease, not just peripheral symptoms.

Mechanisms of generalized pain and how acupuncture acts

  1. Central sensitization

    In fibromyalgia, the dorsal horn neurons of the spinal cord become hyperexcitable — they respond in an amplified manner to stimuli that would not normally be painful. This "volume amplification" of the nervous system explains why light pressure, temperature changes, and even clothing can generate pain.

  2. Dysfunction of descending inhibitory pathways

    The brain has systems that "filter" pain — the descending inhibitory pathways, mediated by serotonin and norepinephrine. In fibromyalgia, these filters function insufficiently, allowing stimuli that should be blocked to reach the cortex as pain. Low-frequency electroacupuncture (2 Hz) specifically activates these pathways.

  3. Autonomic dysregulation

    Patients with fibromyalgia present chronic sympathetic hyperactivation — elevated resting heart rate, reduced heart rate variability, alterations in sleep and digestion. This autonomic dysregulation perpetuates the pain-fatigue-insomnia cycle. Acupuncture restores sympathetic-parasympathetic balance.

  4. Neuroinflammation and glia

    Recent studies demonstrate activation of glial cells (microglia and astrocytes) in the central nervous system of fibromyalgia patients. This neuroinflammation maintains central sensitization. Electroacupuncture can modulate glial activity and reduce central inflammatory mediators.

    Difficulty with concentration and memory ("fibro fog")

  5. 05

    Increased sensitivity to pressure, temperature, and noises

  6. 06

    Morning stiffness that improves over the course of the day

  7. 07

    Blood and imaging tests normal or without findings that explain the pain

Myths and facts about fibromyalgia

Myth vs. Fact

MYTH

Fibromyalgia is not a real disease — it is psychological

FACT

Fibromyalgia is a condition recognized by the World Health Organization (ICD-11), with documented neurophysiologic mechanisms — central sensitization, dysfunction of descending inhibitory pathways, and neuroinflammation. It is not "psychological", although emotional factors influence its expression. Functional neuroimaging studies demonstrate real alterations in cerebral pain processing.

MYTH

If tests are normal, there is no treatment

FACT

Normal laboratory tests are expected in fibromyalgia — the problem is in central pain processing, not in peripheral tissues. Treatment exists and involves neuromodulation (pharmacologic and non-pharmacologic), aerobic exercise, sleep hygiene, and medical acupuncture. The absence of abnormal test findings does not mean the absence of effective treatment.

MYTH

Acupuncture does not work for central pain like fibromyalgia

FACT

Electroacupuncture acts directly on central mechanisms: it activates descending inhibitory pathways, releases endogenous opioids, modulates glial activity, and rebalances the autonomic nervous system. Randomized clinical trials demonstrate improvement in pain, fatigue, and sleep quality in fibromyalgia patients treated with medical acupuncture.

The treatment that regulates the entire system

Treatment protocol

Assessment and differential exclusion
1st–2nd visit

Investigation to exclude systemic causes: hypothyroidism, autoimmune diseases, vitamin D deficiency, anemias. Assessment of fibromyalgia diagnostic criteria. Mapping of concomitant trigger points. Assessment of sleep pattern and physical activity level.

Systemic neuromodulation
Sessions 1–6

Low-frequency electroacupuncture (2 Hz) at systemic neuromodulation points: LI-4, ST-36, SP-6, GV-20. Goal: activate descending inhibitory pathways and autonomic regulation. Frequency: 1–2 sessions per week. Monitoring of sleep quality and pain scale.

Treatment of peripheral trigger points
Sessions 4–10

Dry needling of the most painful trigger points — prioritizing trapezii, suboccipitals, infraspinatus, and gluteus medius. Approach by region: cervical, shoulder girdle, lumbar, limbs. Peripheral treatment reduces the "nociceptive bombardment" that feeds central sensitization.

Consolidation and self-management
Sessions 10–16

Progressive spacing of sessions. Guidance on low-impact aerobic exercises (walking, swimming, hydrotherapy). Sleep hygiene. Stress management techniques. Biweekly or monthly maintenance sessions according to individual response.

Frequently Asked Questions

Fibromyalgia is a chronic condition that, with current knowledge, has no definitive cure — but it has treatment that can relieve symptoms. Medical acupuncture can reduce pain intensity, improve sleep quality and fatigue, and help reduce medication consumption in some patients. The goal is functional remission: enabling quality of life, physical activity, and functionality.

Treatment of fibromyalgia is longer than for localized conditions. An initial cycle of 10–16 sessions (1–2 times per week) is recommended to assess the response. Most patients note sleep improvement in the first 3–4 sessions and pain improvement from the 6th–8th session. After the initial cycle, biweekly or monthly maintenance sessions help maintain results.

Yes — medical acupuncture is frequently used in combination with pharmacologic treatment (duloxetine, pregabalin, amitriptyline). The approaches are complementary: medication acts on central neurotransmitters while acupuncture modulates inhibitory pathways and autonomic regulation. Some patients are able to reduce doses over the course of treatment. Any medication adjustment should be guided by the attending physician.

Initially, exercise may seem to worsen symptoms — but this is transient. The scientific evidence is clear: regular low-impact aerobic exercise (walking, swimming, water aerobics) is one of the most effective interventions for fibromyalgia. The key is gradual progression — starting at low intensity and increasing as tolerated. The physician advises the best reintroduction strategy.
