What does it mean if you feel a needle-pricking sensation during moxibustion, and what should you do about it?

Generally, a needle-pricking sensation during moxibustion may be caused by heat stimulation, improper operation, skin allergy, herpes zoster, or peripheral neuritis. Appropriate measures such as general management or medication can be chosen based on the specific situation. Details are as follows:

1. Heat Stimulation

The high temperature generated by the burning moxa stick stimulates the nerve endings in the skin during moxibustion, causing a brief needle-like sensation. To prevent this, increase the distance between the moxa stick and the skin appropriately, control the duration of moxibustion, and avoid prolonged treatment on the same area.

2. Improper Operation

If moxa ash falls and burns the skin, or if the angle of moxibustion causes excessive heat concentration in one area, a pricking sensation may occur. Clean off the ash promptly, keep the moxa stick stable, have someone supervise the procedure, and immediately remove the moxa stick if discomfort arises.

3. Skin Allergy

Some individuals may be sensitive to the components of moxa wool, leading to local inflammatory reactions upon contact, manifesting as itching, pain, or a needle-pricking sensation. Discontinue moxibustion, clean the skin with lukewarm water, and take antihistamines such as cetirizine hydrochloride tablets, fexofenadine hydrochloride tablets, or loratadine capsules under medical guidance.

4. Herpes Zoster

Reactivation of the varicella-zoster virus affects both the skin and nerves, and moxibustion may trigger sharp, needle-like pain. Seek medical treatment promptly. Follow doctor’s instructions to take acyclovir tablets, valacyclovir tablets, or famciclovir tablets, and keep the affected area clean and dry.

5. Peripheral Neuritis

Nerve damage leads to abnormal peripheral sensations, which may be intensified by the thermal stimulation of moxibustion, resulting in a needle-pricking feeling. Under medical supervision, take vitamin B1 tablets, mecobalamin tablets, or vitamin B12 injections, combined with local massage to improve circulation.

Before performing moxibustion, clean the skin and use high-quality moxa sticks. If needle-like sensations frequently occur or are accompanied by rashes or severe pain, stop immediately and seek medical advice. In daily life, protect the skin and avoid excessive stimulation. Individuals with underlying neurological conditions should consult a doctor before undergoing moxibustion.
