You may have seen people with big, circular, purple bruises in areas of their body, such as shoulders, legs, back, arms, etc. These are most likely from a cupping session. The name comes from the cups that we place on the problem area. We use silicone cups instead of the traditional glass jars. The air from the cup is pumped out to create a vacuum that draws blood to the surface to promote healing. You should not always expect to be left with a big bruise or experience soreness. Cupping is not a painful process, but you should feel the release of tension, just like with a massage.
