One of the most powerful way for stimulating the pain points is their piercing with Sujok Needle. Acupuncture Su-Jok needles are very fine and thin - 15 microns. Unlike the acupuncture needles, which are used in the traditional acupuncture, this needle can be stuck by the sick person himself / herself. Several needles are fixed in one pain point or zone. Sujok Needle is stuck at the depth of one to three millimeters depending on the setting place.
