In my experience most doctors are scummier than prison guards. They couldn't care less about you if you have MediCal (State healthcare in California).
My dad's been trying to get a decisive diagnosis of growths on his liver, but after doing a biopsy (which took 6 months to get) they still have no clue what's up and told him to come back in another 6 months. We found out about these growths because he went in for a physical after a bout with meningitis that the emergency room didn't diagnose or treat. Fucking meningitis!
I'd post more, but I'm on Mobile. I have about 4 more similar stories.
