 [ Symptoms ] when i have pimple or blackheads they leave scars what should i use [ Disease ] as you know i cannot see your throat and examine you over the internet and unfortunately your description is really not specific enough for me to even guess a medical provider must see these things first hand a mono test taken early in the course of an illness may not be very accurate so your medical provider should consider doing an ebv titer a very sensitive mono test if the clinical findings warrant it a z pack is not the treatment of choic for strep so perhaps a repeat strep culture is indicated as well not the rapid strep test and while you are at it a cbc complete blood count would be helpful information the vast majority of sore throats are viral but sometimes this virus is mono so this diagnosis needs to be revisited
