I have an itchy right tonsil and when i sit or lay down a stuffynose?

Dr. can check throat: New throat symptoms can be from a strep throat infection (antibiotics needed), a cold or influenza (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, a person sees the doctor if the throat symptom is bothersome, recurrent, or won't go away quickly (mainly to check for strep throat). Throat lozenges sometimes can help decrease throat symptoms.
