Causes
Many things can cause a sore throat. They may be:
- Viral infections such as the flu, mononucleosis, and the common cold
- Bacterial infections such as strep throat
- Mucus that drains from the sinuses
- Drinking alcohol or smoking
- Breathing polluted air
- Seasonal or other allergies
- Acid reflux
- Pieces of food collecting in the tonsils
- Certain immune or inflammatory problems
Risk Factors
Sore throats are more common children, teens, or people aged 65 years and older. Things that raise the risk are:
- Being near someone with an infection involving the throat or nose
- Being exposed to:
- Cigarette smoke
- Toxic fumes

- Hoarse voice, cough, or problems breathing
- Red or irritated-looking throat
- Swollen tonsils

Diagnosis
The doctor will ask about symptoms and past health. A physical exam may be done. It will focus on the mouth, throat, nose, ears, and lymph nodes in the neck.
Tests may include:
- Rapid strep test or throat culture—swabbing the throat to check for strep throat
- Blood tests—to check for causes of the sore throat
- Mono spot test—to check for mononucleosis
Treatment
Treatment depends on the cause of the sore throat. Options may be:
- Medicines to ease symptoms, such as:
- Antibiotics—for a sore throat caused by a bacterial infection
- Throat lozenges—to ease pain
- Decongestants and antihistamines—to ease a stuffy or runny nose
- Numbing throat spray
- Corticosteroids—to ease discomfort or help breathing, if there is trouble
- Self-care such as rest and lots of fluids
Prevention
To reduce the risk of a sore throat:
- Wash hands often
- Stay away from people who are sick
