My PT guy said they're apparently finding real effects for cupping. I don't remember the details, but the outline was that cupping is controlled bruising, and your body reacts to bruising by going into "fix-it mode" (that's the technical medical term) in that area, and that can help speed recovery from other injuries in that area.

So it's not "detoxification", but rather stimulating healing functions.

This was a two-minute conversation, so...
