When a Sore Throat Will Not Clear
A sore throat lasting more than two weeks is not just a lingering cold. While most sore throats are viral and resolve within a week, a persistent sore throat may indicate a bacterial infection, an underlying inflammatory condition, or a combination of problems affecting the ears, nose, and throat simultaneously. If you have been suffering for three weeks or more, it is time for a thorough assessment.
Common Causes of Persistent Sore Throat
Streptococcal pharyngitis: A bacterial infection of the throat caused by Group A Streptococcus. It produces intense pain, congestion at the back of the throat, and often a high temperature. Unlike viral sore throats, streptococcal infections require antibiotic treatment to resolve and to prevent complications such as rheumatic fever.
Otitis media: Ear infections frequently accompany throat infections, particularly when the Eustachian tubes become blocked. You may notice heaviness, pressure, or reduced hearing in one or both ears alongside the sore throat. Examination with an otoscope will show inflammation of the tympanic membrane.
Post nasal drip: Chronic nasal blockage can cause a constant drip of mucus down the back of the throat, producing irritation and a persistent sore feeling. This is common after a respiratory illness and can last for weeks.
Acid reflux: Silent reflux (laryngopharyngeal reflux) can cause a chronic sore throat, a feeling of mucus in the throat, and a need to clear the throat repeatedly, without the typical heartburn symptoms.
What to Expect at Your Consultation
At Clinique Alpa, we conduct a systematic assessment that includes temperature, heart rate, and oxygen saturation measurements; otoscopy to examine both ear canals and tympanic membranes; throat examination to assess for congestion, pus, or tonsillar enlargement; chest auscultation to exclude a lower respiratory tract infection; and, where indicated, review of recent blood tests including full blood count, CRP, and iron studies.
Treatment Options
Treatment depends on the diagnosis. For confirmed bacterial infection, we prescribe an appropriate antibiotic. The choice depends on the clinical picture and any drug allergies. In patients with a history of gastritis or stomach sensitivity, we prescribe a proton pump inhibitor alongside the antibiotic for gastric protection.
Supportive measures include bed rest during the acute phase, increased fluid intake of two to three litres daily, honey and lemon in warm water for symptomatic relief, and avoidance of irritants such as smoking and alcohol.
If there is concurrent musculoskeletal pain, such as upper back or neck pain, we can address this at the same appointment. Co occurring pain often worsens the overall feeling of being unwell and can itself be a source of fatigue and poor sleep.
Iron Deficiency and Recurrent Infections
Low iron levels, particularly low ferritin, can contribute to recurrent infections, fatigue, and poor recovery from illness. If blood tests reveal iron deficiency, we discuss options including dietary modification, oral supplementation, and intravenous iron infusion. For patients who cannot tolerate oral iron due to gastritis or side effects, intravenous infusion is an effective and well tolerated alternative.
Frequently Asked Questions
Do I need antibiotics for a sore throat?
Not always. Most sore throats are viral and will resolve without antibiotics. However, if clinical examination reveals signs of bacterial infection such as pus on the tonsils, significantly inflamed tympanic membranes, or a high temperature, antibiotics are appropriate and will speed recovery.
Should I go to A&E for a sore throat?
Only if you are having difficulty breathing, are unable to swallow fluids, or are drooling (which may indicate a peritonsillar abscess). For a persistent but non emergency sore throat, a private GP can see you the same day and provide treatment without the hospital wait.
Can a sore throat last a month?
Yes, particularly if it is caused by or complicated by reflux, post nasal drip, or an untreated bacterial component. A thorough assessment is needed to identify and treat the specific cause.
