So the doctor sent you home because you don't know what you have.

yes sirre bob. because i had no clue how i got it, i was told there was nothing to do but clean the area. see if it goes away, it hasnt and i have used rash creams and nothing happens. im confused if its all doctors or just doctors here in TN that shouldnt have gotten their license.
