Cupping therapy is an ancient form of alternative medicine in which a therapist puts special cups on your skin for a few minutes to create suction. 

People get it for many purposes, including to help with pain, inflammation, blood flow, relaxation and well-being, and as a type of deep-tissue massage.
Cupping increases blood circulation to the area where the cups are placed. 

This may relieve muscle tension, which can improve overall blood flow and promote cell repair.
