Each time, 3-4 holes are made in the bone surface, with different directions, in order to fully release the pressure in the bone, and let it bleed naturally for 1-2 minutes after the needle is removed, so as to reduce the pressure in the bone. It is not advisable to repeat the same area for several consecutive needle treatments.
