What causes sore throats?
Allergies, dry air, and outdoor pollution, as well as illnesses like the common cold, flu, measles, chickenpox, mononucleosis (mono), and the croup, can all cause sore throats. These illnesses are all viral infections that will not respond to antibiotics.
Bacterial infections are responsible for only a small percentage of sore throats, including those linked with strep throat, whooping cough, and diphtheria. Most doctors recommend calling a doctor only in cases of severe sore throat accompanied by a fever, or when swollen tonsils block the throat.
Even if a sore throat isn’t serious enough to warrant a trip to the doctor, it’s still painful and may interfere with a good night’s sleep. Fortunately, there are a number of at-home remedies you can use to soothe the pain and irritation.
