It is normal to have itchy cupping areas. The main reason is that the capillaries at the cupping area are broken and the blood and tissue fluids penetrate each other, stimulating the nerves and causing an itchy sensation. Many patients not only have an itchy feeling, but also have a large amount of congestion in the skin, even blackening. Clinically this modality can be very effective in stimulating the body’s immune system and regulating the body’s internal environment, which is very effective in treating other internal diseases such as illness and pain. According to TCM, the itchy cupping area indicates that the wind, cold, damp and other disease evils in the body can be well removed, which is a positive direction of treatment and can be complemented by other means of cupping such as oral medication, which will be more effective in getting rid of disease evils in the body.
