Throat irritation: main causes and when to see a doctor

No fever, your voice is fine, but your throat tickles and scratches. Let's calmly figure out where the tickling comes from and at what point it's time to see a doctor.

What throat irritation is

Tickling is a common symptom of pharyngitis, inflammation of the mucous membrane of the pharynx. With pharyngitis, a person feels discomfort, pain or scratching in the throat, and swallowing is often painful.

What happens inside: the back wall of the pharynx — the area between the tonsils and the larynx — swells. Accompanying signs vary: a dry throat, pain when swallowing, redness deep in the mouth, bad breath, a mild cough, enlarged cervical lymph nodes. Fever is not obligatory — with acute pharyngitis it rises to 37.5–38 °C, less often higher. So a tickling throat without fever is a common picture, not a sign of an advanced case.

Why the throat tickles: infections, irritants and more

Most often a viral infection is to blame — a cold, flu, as well as Coxsackie virus and mononucleosis. Bacteria are less common: group A streptococcus, and in isolated cases the causative agents of gonorrhea and chlamydia. The list of causes also includes staphylococci and pneumococci, and among the rare ones — Candida fungi.

The throat can tickle without microbes too: inhaling hot, cold or polluted air, chemical irritants and tobacco smoke irritate the mucous membrane. A nearby source is often to blame — sinusitis, rhinitis, tooth decay; snoring during sleep and pharyngeal injury also play a role. The doctor determines the cause of the tickling during examination. Most cases occur in the cold months, and the disease spreads easily within families and among close contacts.

Persistent throat irritation and coughing: possible causes

If the tickling lasts not a week but months, it is usually chronic pharyngitis: it arises from prolonged irritation of the mucous membrane and runs in phases of exacerbation and remission. The symptoms are milder — dryness or tickling, often a dry and distressing cough.

If the tickling and cough persist for a long time, the doctor looks for the cause. Pharyngitis can develop against a background of sinusitis, rhinitis or tooth decay, and also because of snoring; smoking and tobacco smoke are a cause in their own right. Dust and irritating gases most often cause acute pharyngitis. This cannot be distinguished by eye: on examination there is marked redness of the mucous membrane, sometimes small ulcerations.

When throat irritation requires a doctor's examination

The benchmarks are simple, the list is short:

• tickling and pain do not go away within a week;
• throat pain recurs frequently;
• there is a high fever, enlarged lymph nodes in the neck or a rash;
• the child is under 5 years old and needs help with their throat — this calls for a doctor, not a pharmacy;
• there is a feeling of a lump in the mouth or neck, or a sore in the mouth persists for more than 3 weeks.

Separately — a weakened immune system (for example, due to diabetes or chemotherapy) and signs of dehydration: less urine than usual or dark, strongly smelling urine. The doctor examines the throat, takes a rapid test or culture if streptococcus is suspected, and orders tests for other suspicions; if there is a risk of HIV infection, the list includes an HIV test. Complications of pharyngitis are otitis, sinusitis, and an abscess near the tonsils.

Tickling on its own is not a reason to call an ambulance. You should call 103 or 112 if, against the background of a throat problem, difficulty breathing or inability to swallow appears, drooling (a sign that swallowing is not possible), a whistling high-pitched sound when breathing (stridor), or severe symptoms that rapidly worsen.
