mort, like I said, those bruises are a standard side effect and are purely cosmetic in their effect. when I have cups on my upper back or on the outer part of my quads I get bruises (mostly on my back), but on my lower back and hamstrings I don’t get any bruising at all. there is pinkness when they first come off but after a very short time you can’t see anything at all.
you don’t need to avoid the bruises. it’s actually a sign that it’s working…
