Pharyngitis: If a doctor made a diagnosis then that doctor also prescribed you a treatment based on that diagnosis. Since you have provided no information, not even your age let alone your medical history no response can be provided. Are you 7 or 77? If there is no thoughtful question posted with necessary information, no informative response can be expected.
