Sore Throat: Symptoms, Causes & When to See an Online Doctor in the UK

A sore throat (medically called pharyngitis, or tonsillitis when the tonsils are involved) is inflammation at the back of the throat. It is one of the most common reasons UK adults and children look for an online doctor — and most cases are not serious.

The throat may feel scratchy, raw, tight or painful, especially when you swallow or talk. You may also notice a hoarse voice, swollen neck glands, a mild fever or a runny nose if a cold or flu virus is the cause.

The good news: the vast majority of sore throats in the UK get better on their own within 5 to 7 days. The job of an online GP is to identify the small number that need antibiotics or further investigation, and to help everyone else feel better faster.

Sore-throat symptoms vary depending on the cause. The most common ones include:

• Pain or scratchiness in the throat, worse on swallowing
• Red, swollen tonsils — sometimes with white patches or pus
• Tender, swollen lymph nodes in the neck
• Fever, headache, body aches and tiredness
• Hoarse or muffled voice
• Cough, runny nose, sneezing (more typical of viral infections)
• Bad breath or a sour taste in the mouth

Viral vs bacterial — how to tell the difference

This is where most patients want guidance, because it determines whether antibiotics are likely to help. As a rough guide:

• More likely viral: sore throat alongside cough, runny nose, sneezing, hoarseness, mild fever, gradual onset.
• More likely bacterial (e.g. strep): sudden onset, high fever, swollen tender glands, white patches on tonsils, no cough, severe pain on swallowing.

Even doctors cannot tell with 100% certainty just by looking — that's why GPs use validated scoring tools (FeverPAIN and Centor) to estimate the likelihood of a bacterial cause and decide whether antibiotics are appropriate. Your online doctor can walk you through this during your consultation.

The most common causes seen in UK general practice are:

• Viral infections (around 70–80% of cases): common cold viruses, influenza, COVID-19, glandular fever (Epstein-Barr virus).
• Bacterial infections: most often Group A Streptococcus ("strep throat"). These can cause tonsillitis and may benefit from antibiotics.
• Irritants: dry indoor air, smoking, vaping, alcohol, pollution.
• Allergies: hay fever and post-nasal drip.
• Acid reflux (GORD): stomach acid irritating the throat, often worse in the morning.
• Voice strain: shouting, prolonged talking, singing.

For most sore throats, the NHS and NICE recommend self-care first. Things that genuinely help:

• Pain relief: paracetamol or ibuprofen at standard doses (check the leaflet, or ask a pharmacist if pregnant or on other medication).
• Fluids: drink plenty of water; warm drinks with honey and lemon can soothe (avoid honey for children under 1).
• Salt-water gargles: half a teaspoon of salt in a glass of warm water, several times a day (adults and older children).
• Throat lozenges or sprays: available over the counter; some contain a mild local anaesthetic.
• Rest your voice and avoid smoking, vaping and alcohol.
• Humidify the air if your home is very dry, especially overnight.

You usually do not need antibiotics. Most viral sore throats peak around day 3 and improve significantly by day 5–7.

An online GP consultation is well-suited to a sore throat. During a 10–15 minute video call, your doctor will:

• Take a focused history of your symptoms, duration and any red-flag features.
• Ask you to show your throat and feel your neck for swollen glands.
• Apply a clinical scoring tool (FeverPAIN or Centor) to estimate whether your sore throat is likely bacterial.
• Advise on self-care and pain relief.
• Issue a private prescription for antibiotics if clinically appropriate, sent electronically to your UK pharmacy.
• Provide a private sick note (fit note) if you need time off work.
• Refer you for in-person assessment if anything suggests a more serious problem.

Online consultation is particularly useful if you cannot get a same-day NHS appointment, do not have a registered NHS GP, or simply prefer the convenience of being seen at home.

Booking is quick — most patients are seen within 15 minutes during opening hours. Before the call, find a quiet, well-lit room and have a torch (your phone torch is fine) ready so the doctor can see your throat clearly.

The GP will introduce themselves, confirm your details, and lead the consultation calmly. If antibiotics are needed, the prescription is sent directly to your chosen UK pharmacy. If you need a sick note, you will receive it by email after the call.

Everything is private and confidential, and a clinical record is made for continuity of care.
