Pepperoni Pizza?

Can you guess what this is? Dave and I go to an Acupuncture/Chiropractor for aches and pains. The main doctor is a 72 year old man form Taiwan who has only been in the U.S. for 21 years. His wife works with him as does his son. Dave went today and this is what he came home like. He had a treatment called cupping where glass bulbs are heated with a fire and positioned on the skin. The suction in the bulb draws the blood in the skin up to four inches down to increase circulation, reduce inflammation and release toxins in the blood stream. It looks strange, but it works!
