I had a guy I was dancing with grab my left breast and he quickly sucked on my cleavage of course I slapped him hard! I woke up the next day to a very bad hickey bruise that covered the top of my entire breast. Now the bruise is going away some but I feel a small lump round flat the size of a quarter?? The lump wasn t there before because I ve been checking that area since this happened. I m going to doctor Monday. I m 43 yrs old. Is this probably just a fat necrosis under my skin?
