A sore throat, or pharyngitis, is a condition characterized by pain, scratchiness, or irritation of the throat, which often worsens when you swallow

. The most common cause of a sore throat is a viral infection, such as a cold or the flu

. Other causes of a sore throat include:

  • Bacterial infections, like strep throat caused by Streptococcus pyogenes (group A streptococcus)
  • Allergies to pet dander, molds, dust, and pollen
  • Dryness, such as from dry indoor air or breathing through the mouth due to chronic nasal congestion
  • Irritants like outdoor air pollution, tobacco smoke, or chemicals
  • Chewing tobacco, drinking alcohol, and eating spicy foods
  • Exposure to chemical irritants

A sore throat caused by a viral infection usually lasts five to seven days and doesn't usually require medical treatment

. However, if your sore throat is caused by a bacterial infection, your doctor or pediatrician will prescribe antibiotics to prevent complications

. It is essential to identify the cause of your sore throat to determine the appropriate treatment. If your symptoms do not improve within a few days or get worse, consult a healthcare professional
