That bruise will last as well. I had a knot in my right shoulder that would not go away. For 6 months it was hurting. I would have my DH massage it, I would go and have massages. Nothing worked. I had my accupuncturist cup it twice, and it has not bothered me since. For me the cupping really worked. The bruise will be there for most of the week. But it will go away.
