Whats the main cause of swollen lymph nodes in your neck? im just getting over a cold and recently it hurts on right side when i swallow. get checked?

Dr. can check throat: Throat pain can be from a strep throat infection (antibiotics are 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 sore throat is bothersome, recurrent, or doesn't go away quickly (mainly to check for strep throat). Throat lozenges and Tylenol (acetaminophen) or Motrin can help decrease throat pain.
