I think this might be because of "cupping therapy". I don't know if you've watched the swimming competitions in the olympic, but I noticed that some of the swimmers such as Phelphs had these circular bruises on them. turns out that's what it was. I think it may be some type of pain-relieving therapy? although it is considered as a pseudoscience because there are no determined health benefits (much like bloodletting for indigestion or acupuncture)
People still do that? ..
Right the shape does look like being cupped...
