Why your throat hurts
- Most common cause
- Viruses
- Viral sore throats
- Usually improve within about a week
- Antibiotics help
- Only for bacterial causes like strep
- Best first steps
- Rest, fluids and pain relief
A sore throat, or pharyngitis, is inflammation at the back of the throat. It makes swallowing and talking uncomfortable and often arrives alongside a cold.
Viruses cause most sore throats, including the ones behind colds, flu, COVID-19 and mono. Bacteria, mainly strep, cause a smaller share. Allergies, dry air, acid reflux and smoke can also irritate the throat without any infection.
Identifying the likely cause matters, because it decides whether you need a test, an antibiotic or simply time and good symptom relief.
What's behind your sore throat?
The other symptoms you have offer useful clues:
| Feature | Typical clues | What usually helps |
|---|---|---|
| Cold or other virus | Runny nose, cough, hoarseness, gradual start | Rest, fluids and pain relief |
| Strep throat | Sudden pain, fever, no cough, swollen tonsils or neck glands | A strep test, then antibiotics if positive |
| Flu or COVID-19 | Fever, body aches, tiredness, cough | Testing; antiviral medicine for some people |
| Mono | Marked fatigue and swollen glands lasting weeks, often in teens and young adults | Rest and medical follow-up |
| Allergies | Scratchy throat with sneezing, itchy eyes or postnasal drip | Allergy treatment |
| Dry air or reflux | Worse in the morning, burning, no fever | Humidifier; reflux management |
Sore throat symptoms
Depending on the cause, you may notice:
- A scratchy, raw or burning feeling
- Pain that gets worse when you swallow or talk
- Red or swollen tonsils
- A hoarse or muffled voice
- Tender, swollen glands in the neck
- Cold symptoms such as a runny nose, cough or sneezing
See a provider soon if your sore throat:
These can point to an infection that needs testing or treatment:
- Lasts longer than a week, or keeps coming back
- Comes with a fever and no cold symptoms
- Is much worse on one side
- Comes with a rash or joint pain
How the cause is found
Your provider starts with your symptoms: how quickly the sore throat began, whether you have a cough, fever or runny nose, who you've been around and how long it has lasted.
Many sore throats don't need any test. If strep is a possibility, a rapid strep test or throat culture is the standard next step. Flu and COVID-19 tests can guide treatment, and a blood test can check for mono when symptoms drag on.
Treatment and relief
Antibiotics don't help viral sore throats and can cause side effects, so for most people treatment means easing symptoms while the body clears the virus. When strep is confirmed, antibiotics are the right choice.
| Pain relievers | Acetaminophen or ibuprofen, if they're safe for you |
|---|---|
| Lozenges or throat sprays | Numb the throat for short-term relief. Avoid lozenges for young children. |
| Honey | In warm tea or water. Never give honey to babies under 1. |
| Salt-water gargle | About half a teaspoon of salt in a glass of warm water |
| Humidifier and fluids | Moist air and plenty of drinks keep the throat from drying out |
