After cupping kidney position is very black how to return a responsibility

After cupping, the kidney part is very black, which may be related to meridian blockage, blood vessel damage and damp-heat factors.

1. Meridian blockage

If there is meridian blockage, in the cupping process, due to the negative pressure, the blocked meridians will be more blocked, resulting in the deepening of the color of the kidney area.

2. Blood vessel damage

If the negative pressure generated during cupping is too large, it can lead to the rupture of blood vessels under the kidney area, resulting in bleeding, which can be deposited under the skin, resulting in black stasis.

3. Damp-heat

If there is damp-heat in the kidney area, the cupping process may help to expel moisture and heat, thus making the area darker.
