My throat been sore for a week now but been using cepacol and finally i feel progress but now im feeling light headed and my ears more sensitive so sounds. what can it be?

Dr. can check throat: New throat pain can be from a strep throat infection (antibiotics are needed), a cold, influenza, or "mono" (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, a person sees the doctor if the sore throat is bothersome, recurrent, or doesn't go away quickly (mainly to check for strep throat).
