A sore throat can be caused by a viral infection, tonsillitis, dry air, smoke, allergies, voice strain, or reflux. Many uncomplicated sore throats improve within about a week, but severity, duration, and associated symptoms matter. A description of pain alone cannot reliably tell whether antibiotics or specialist care are needed.
Common patterns and self-care
A sore throat with a runny nose, cough, or hoarseness often occurs with a viral respiratory infection. Fever, tender neck glands, and inflamed tonsils may lead a clinician to consider a throat infection that needs testing. Reflux or repeated voice strain may cause irritation without an acute infection, particularly when symptoms recur or are worse after particular activities.
Rest, fluids, avoiding smoke, and suitable pain relief can help comfort while the illness settles. The right medicine depends on age, pregnancy, allergies, medical conditions, and other drugs. Do not start leftover antibiotics or share medication; unnecessary treatment can cause side effects without improving a viral illness.
When a clinician may test or examine
A clinician examines the throat and considers symptom duration, fever, exposure, tonsil appearance, swollen glands, and ability to drink. A swab may be recommended when bacterial infection is a possibility and the result would influence treatment. Persistent or recurring symptoms may prompt assessment for reflux, voice disorders, tonsil problems, or other causes.
Seek a non-urgent appointment if the sore throat is not improving after about a week, keeps returning, or is associated with a persistent neck lump, mouth ulcer, or hoarseness. People with a weakened immune system or complex medical conditions may need earlier advice.
Symptoms that should not wait
Get emergency care for difficulty breathing, inability to swallow saliva, drooling, a rapidly increasing swelling in the throat or neck, or severe symptoms that worsen quickly. These signs can indicate an airway problem or a deep throat infection.
Prompt assessment is also important for dehydration, a severe sore throat with high fever, muffled voice, difficulty opening the mouth, or severe one-sided pain. These features may need more than routine home care.
Common questions
How long should a usual sore throat last? Many uncomplicated cases improve within about a week, but worsening, persistent, or severe symptoms should be assessed.
Can I tell whether it is bacterial from the colour of my throat? Not reliably. The examination and, when indicated, testing guide the decision.
