Why do I feel exhausted all over after acupuncture?

Generally speaking, feeling tired all over after acupuncture may be caused by factors such as mental tension, weak constitution, excessive acupuncture stimulation, improper needling, or deficiency of qi and blood. A detailed analysis is as follows:

1. Mental Tension

If a patient has never undergone acupuncture before or is particularly sensitive to pain, they may become overly mentally tense, causing rapid muscle contraction. After acupuncture, the body gradually relaxes and muscles loosen, which may lead to a sensation of general fatigue. This is usually normal and patients need not worry excessively. It is recommended to get adequate rest, maintain regular sleep habits (early to bed and early to rise), avoid staying up late, and ensure sufficient sleep.

2. Weak Constitution

If a patient inherently has a weak constitution and receives relatively strong acupuncture stimulation, they may experience generalized fatigue following treatment. In such cases, no special treatment is required; symptoms typically resolve with rest.

3. Excessive Acupuncture Stimulation

If the duration or intensity of stimulation is too great, the needle sensation may become particularly noticeable. Some sensations may persist for a long time, leading to complaints such as increased lower back pain after acupuncture.

4. Improper Needling

If needling is performed improperly or stimulation is too intense, it may cause excessive anxiety in the patient, potentially leading to needle fainting (vasovagal reaction). This can manifest as post-acupuncture fatigue. In such cases, the patient should be laid flat in a head-high, feet-low position, the area should be well ventilated, and if symptoms persist, emergency acupoints such as Baihui (GV20) may be stimulated.

5. Qi and Blood Deficiency

If a patient lacks physical activity or has poor dietary habits, this may lead to deficiency of qi and blood. Acupuncture therapy increases the body's metabolic functions, which might exacerbate existing deficiencies, resulting in feelings of overall fatigue, possibly accompanied by symptoms such as weakness and dizziness. Prolonged acupuncture sessions may worsen these symptoms. Patients are advised to rest adequately. For severe cases, follow medical advice to take herbal formulas such as Ren Shen Gui Pi Wan (Ginseng Combination) or Ren Shen Yang Rong Wan (Ginseng Nutritive Pills) to replenish qi and blood.

In summary, if patients experience any discomfort, it is recommended to seek timely medical evaluation at a hospital to prevent serious complications.
