Fire needling is actually a method of using fire to burn needles until they are white and bright, and quickly piercing them into acupuncture points in order to treat disease. Although it may sound and look a bit intimidating, in practice, the doctor is able to actually relieve some of the pain by moving the needles in quickly, pulling them out quickly after they are inserted at the proper depth, and pressing the holes with a dry cotton ball. The patient will feel pain when the fire needles are tied, but this pain is similar to the common pain of ordinary acupuncture, the local warmth is stronger after the fire needles. The clinical application is usually milli-fire needles, the eye of the needle is smaller, the lesion is also smaller, the pain is lighter, most patients with milli-fire needles for treatment said the pain is acceptable. Some eczema patients with more pronounced local itching sometimes ask for a few more needles, so there is no need to be afraid.
