Its began at the back, about 1 mm itching I scratched it became a sticky bloody wound, the tunnels are at the forehead, in the mouth, at the hands, wounds all over the body, but in a line, the distance is always 2,5-4 cm straight. At the hands I can see, it is always at the blood vessel. med. again scabies have already helped, but not cured. Permetrin cream, shampoo etc.
