I have a sore throat with small sores on the back of my throat and it hurts to swallow. i also have a stuffy nose. what could this be?

Doctor can examine: New throat pain can be from a strep throat infection (antibiotics needed), a cold or influenza (antibiotics usually not used), or from some cause such as other viruses, allergies, or irritants. Usually, a person sees the doctor if the sore throat is bothersome, recurrent, or doesn't go away quickly. Throat lozenges and Tylenol (acetaminophen) or Motrin (ibuprofen) may temporarily lessen pain.
