About Thrush??

My little sister thinks she have thrush and is scared to demise about going to the doctor because she think they'll swab her thoat. Does anyone know if they'll swab her thoat? i'm not looking this up, but if thrush is what i remember it to be, the whole mouth and throat will be coated.
when i worked contained by the ER/OR rotaions, thrush was so unmistakable that they gave meds lacking a culture
a swab does not hurt at all
if she is worried something like that, wait till she requirements stitches
