Hi, may I answer your health queries right now ? Please type your query here...I have two yellowish green round bruises. One is right above my left breast an the other is about two inches below it on my breast, above the aereola. The higher one was purple and now green. I think they may be the result of getting hit my the car door on a windy day, but I'm not sure. Under each bruise is a very small, moveable lump -- but any lump is scary. I understand this is probably a hemotoma. But could it be something worse? The green bruise has been present for 10 days.
