Chronic Fatigue Syndrome

Chronic fatigue syndrome — also called myalgic encephalomyelitis, or ME/CFS — is a complex, long-term illness marked by severe fatigue lasting six months or more that isn’t relieved by rest. Its defining feature is post-exertional malaise: a worsening of symptoms after physical or mental exertion that can leave a person wiped out for days. Alongside the fatigue come unrefreshing sleep, cognitive difficulties often called brain fog, and frequently pain. The cause remains poorly understood, though it often follows a viral or other infection — including the lingering fatigue some people experience after Lyme disease. It is a real, physiological illness — not something a person can simply push through — and it can be genuinely disabling.

Chronic fatigue syndrome affects the whole body and mind. Common symptoms include:

• Overwhelming fatigue that rest does not relieve
• Post-exertional malaise — a symptom crash after even light activity
• Unrefreshing sleep and other sleep disturbances
• Difficulty with memory and concentration (brain fog)
• Muscle and joint pain, headaches, and sore throat

The exact cause is unknown. A viral illness often triggers it and may involve immune dysfunction, disrupted energy metabolism, and nervous system dysregulation. Because its symptoms overlap with many other conditions, a proper medical diagnosis — one that rules out other causes — is an important starting point.

In Chinese medicine, chronic fatigue is generally understood as a deep deficiency — most often of Qi, the body’s vital energy, frequently involving the Spleen and Kidney systems that govern energy production and reserves. Where there is also stagnation, the exhaustion may be compounded by a sense of heaviness or low mood. Rather than trying to force energy, treatment aims to gently replenish these reserves and restore smoother flow, supporting the body’s own capacity to recover. Dr. Willcox assesses each person’s unique pattern, since no two cases of chronic fatigue present quite the same way.

One of the reasons acupuncture appeals to people with chronic fatigue is that it asks nothing strenuous of the body — the patient simply rests while the treatment does its work. This matters, because exertion can worsen this condition. Acupuncture is thought to help by supporting the nervous system’s balance, easing pain and improving sleep, and gently encouraging the body’s own energy regulation.

The research is limited but cautiously encouraging. A 2025 meta-analysis found that acupuncture — especially combined with rehabilitation — may improve fatigue and quality of life in chronic fatigue syndrome, with the clearest benefit in the near term — though the authors were candid that the included trials were small and inconsistent, and the results should be interpreted with caution. In practice, acupuncture is best understood as gentle, supportive care that may help ease the burden of symptoms.

At Acupuncture Zen, chronic fatigue is often addressed with acupuncture and, where appropriate, moxibustion — a gentle warming therapy — and Chinese herbal medicine, always as a complement to a patient’s medical care.

A first visit begins with an unhurried, respectful conversation about the history of symptoms, sleep, pain, and how much activity tends to bring on a crash — this last point especially, since sessions are always kept gentle and within a patient’s tolerance. Treatment involves fine needles at points chosen to support energy, sleep, and calm, sometimes with gentle warming, followed by a restful period. Because chronic fatigue responds slowly, treatment is approached as gradual, supportive care rather than a quick fix, and is paced carefully to avoid overtaxing the body. Dr. Willcox coordinates with a patient’s physician throughout.
