For the last 8 months or so I have had a bump in the back of my head. It is visible to the eye specially because I cut my hair short. Sometimes I feel it small and sometimes I feel it bigger than usual. I am a healthy 20 year old that have had no surgeries or problems, so I really do not know what it is. I have gone to get it check out but they just ran some blood test and I came perfectly find. The bump doesn't hurt if I push on it . It also feels kind of squishy, and can move the bump a little bit. I want to get it check out again, but I don't know what kind of physician to go to.
