I am a 3rd year medical student in need of advice:: My friend accidentally hit me in the forehead with the thin side of a cellphone about 3 weeks ago... the large bump and bruising went away after 1.5 wk, but a small bump, which is still tender to touch, remains. Is this fibrous tissue, a small superficial hematoma, or should i go to the doctor? Ideally, id like to make this go away... Any advice would be great.
