Hi everyone,
I have used cupping lately to treat people with back and shoulder pain. However, I am not too sure what it means when sometime there is no red/ purple mark on those area where the cup have been for at leat 10 minutes. I remember my teacher said that the red mark shows that there is stagnation on the area and if there is no mark or very light color, it means the person has no Qi or very deficency in that area? I don't quite understand this. Does anyone know about this could help me out. THanks
