Some patients get white cupping marks which might indicate the possibility of an iron or B12 deficiency. Cupping can be a great extra way to help diagnosis pain syndromes.
Cupping can be used for back, neck, shoulder, leg, and menstrual pain. It can be used to help loosen phlegm causing a cough. Cupping is great for local tension and aches. Cupping is even safe during pregnancy.
