I was in a car accident Sept 15, 2016......I started at an intersection and a gal made a left turn in front of me, and we crashed into the front bumper of my Trailblaze. I have a big bruise on the inside of my right bosom and developed a dark deep red lump (about the size of a baseball) which about half now is returning normal, and no pain, but the most inner side is deep and developed a hardened, half a baseball-sized lump. I'm thinking it will return to normal and disappear, but do you think I should see my doctor? Thanks, Bette McKinney, Phoenix AZ.
