In those places of the skin, where a pathological process is established, hemorrhagic spots appear - "sha". These places contain an increased amount of lactic acid. The color of the spots can be almost black - this is "inanimate" blood. The appearance of these hemorrhages may frighten the patient, but the procedure itself is almost painless. Only occasionally, with a started process and large hemorrhages, the patient can feel pain, which immediately subsides when the impact on the treatment area ceases. For hours, warm water should be drunk during the day to ensure increased excretion of toxins from the body. After the session, severe fatigue may occur, such as after exercise: the effect of the impact is equal to a distance of 20 km. The frequency of the procedures is 1-2 times a week after the disappearance of the bruises from the previous massage. The course includes 4-6 sessions in combination with other types of massages. Such courses are recommended twice a year.
