SIU Health Services-Don't Go If You Value UR Life

so i called up health services yesterday to bitch about them misdiagnosing me with a negative strep culture and today i talked to the doctor. according to him it is very possible to have a negative strep test and then a day later have strep so bad that ur progressing into scarlettina and another culture can be positive after LESS THAN FIVE MINS. he also told me that emycin clears up strep throat, but dr. wilson told me it doesn't. and they both see strep throat cases all the time. god i don't know who to believe what to believe and i still dont feel any better.
