A sore throat is a common symptom in daily life and can appear at any age. This condition reflects changes in the pharyngeal mucosa and immune system due to many factors.
Burning, itching, or difficulty swallowing can start suddenly and significantly affect daily activities, sleep, and work performance. These symptoms need to be noted to ensure appropriate treatment measures.
Have you ever wondered what is behind a seemingly simple sore throat and when it should be considered an important warning sign?
A sore throat is a common condition that affects swallowing and comfort.
Causes of Sore Throat
A sore throat originates from an inflammatory response of the pharyngeal mucosa to infectious agents, allergies, and environmental stimuli. Correctly identifying the cause helps to choose the right treatment and shorten the duration of discomfort.
Viral infections
Cold viruses, influenza, SARS-CoV-2, and adenovirus invade the mucosa and activate cytokines, causing edema, increased sensitivity of pain receptors, and hoarseness. Depending on the level of immune activation, symptoms are often accompanied by a runny nose, cough, chills, fatigue, and fever.
Bacterial infections
Group A streptococcus (Streptococcus pyogenes) causes red granular pharyngitis, white patches on the tonsils, swollen cervical lymph nodes, and high fever. When treatment is delayed, severe conditions lead to severe painful swallowing and the risk of complications such as scarlet fever, glomerulonephritis, and rheumatic heart disease.
Allergies and irritants
Pollen, animal hair, cigarette smoke, strong alcohol, and spicy foods stimulate the release of histamine, causing congestion and a sore throat. Gastroesophageal reflux sends acid into the throat, causing a burning sensation in the morning and a persistent dry cough.
Environmental triggers
Dry weather, air conditioning, low humidity, PM2.5 pollution, occupational dust, prolonged loud talking, and passive smoking dry out the mucous membranes, causing microtrauma and increasing the risk of recurrent inflammation.

Symptoms and Warning Signs
Sore throat symptoms range from mild discomfort to serious warning signs. Understanding the symptoms helps distinguish common conditions from diseases that require prompt medical intervention.
Typical symptoms
A burning, dry, itchy, or painful swallowing sensation is evident. Patients often have hoarseness, a weak voice, and a feeling of something stuck in the throat. Some cases report difficulty swallowing solid foods or pain radiating to the ear.
Associated signs
A dry cough or cough with phlegm, swollen lymph nodes in the neck, fever ranging from mild to high, and general fatigue. Children may refuse to eat, cry, and increase salivation. Adults may have headaches, muscle aches, and reduced concentration at work.
Emergency indicators
A severe sore throat with difficulty breathing, difficulty swallowing saliva, swelling spreading to the neck, or a high fever above 39°C indicates a serious condition. The presence of blood in the sputum or saliva is a sign that requires urgent evaluation.

Diagnosis of Sore Throat
The diagnosis of a sore throat is based on a combination of clinical examination and paraclinical tests. This procedure allows the doctor to determine the exact cause and provide appropriate treatment while preventing long-term complications.
Physical examination
The doctor observes the throat with a light to assess the level of redness, swelling, pus, or white patches on the tonsils. The lymph nodes in the neck are checked for size, tenderness, and density to suggest inflammation.
Throat swab and rapid strep test
A throat swab sample is taken for a rapid test to look for group A streptococcus. Results can be available within minutes, helping the doctor decide whether antibiotics are needed.
Blood tests
A complete blood count test helps distinguish bacterial from viral infections. In some cases, additional antibody or CRP tests are required to assess the level of systemic inflammation.
Diagnostic scores
The Centor and FeverPAIN scores quantify symptoms such as fever, tonsillar white patches, swollen lymph nodes, and cough. These scores help quickly identify the cause before test results are available.
Treatment Options
Treatment of a sore throat involves a combination of medical and natural remedies. The appropriate choice depends on the patient's cause, severity, and overall health. The goal is to relieve pain, control inflammation, and prevent complications.
Medical treatments
Over-the-counter pain relievers and fever reducers, such as paracetamol or ibuprofen, help relieve sore throats, reduce fever, and increase activity. Lozenges and throat sprays contain local anesthetics to soothe the mucous membranes. In cases of streptococcal infection, your doctor may prescribe oral antibiotics to eliminate the bacteria and prevent rheumatic fever. For chronic conditions such as gastroesophageal reflux, acid-suppressing medications or antihistamines are used long-term.
Home remedies & natural relief
Gargle with warm salt water to reduce inflammation and clear mucus. Drinking herbal teas like ginger, chamomile, and mint can help relax and soothe the throat. Honey combined with warm water can help reduce coughs and make swallowing easier. Steam inhalation and use of a humidifier help maintain respiratory tract moisture and prevent dryness.

Complications and Related Conditions
If not treated early, a sore throat can progress to many local and systemic complications. These related conditions affect breathing, immunity, and quality of life and require continuous medical monitoring.
Tonsillitis
Inflammation of the tonsils causes white patches or pus to appear, causing pain when swallowing and bad breath. Severe cases can form abscesses around the tonsils, narrowing the airway.
Laryngitis
Laryngitis causes hoarseness, loss of voice, pain when speaking, and a choking feeling in the throat. A dry cough and mild difficulty breathing often accompany the patient.
Scarlet fever
Streptococcal infection can lead to a rash all over the body, a bright red tongue, and a high fever. The disease progresses rapidly and requires timely medical intervention to limit serious complications.
Rheumatic fever
If a streptococcal infection is not treated adequately, an immune response attacks the heart, joints, and nervous system. Long-term consequences include chronic valvular heart disease.
Chronic pharyngitis
Recurrent inflammation, thickening, and fibrosis of the pharyngeal mucosa, causing a dry, scratchy feeling and a persistent cough.

Prevention Tips
Prevention of sore throat is based on maintaining immune health, reducing exposure to irritants, and protecting the pharyngeal mucosa. Daily habits play an important role in reducing disease risk and limiting recurrence.
Good hygiene and handwashing
Washing hands with antibacterial soap before eating and after contact in public places helps eliminate viruses and bacteria. Covering your mouth when coughing or sneezing protects the community from infection.
Avoiding irritants
Avoid exposure to cigarette smoke, dust, and polluted air. Keeping the living environment clean and airy reduces irritation of the mucosa.
Boosting immunity
Maintaining a diet rich in vitamin C, zinc, and antioxidants helps strengthen resistance. Drinking enough water helps keep the mucosa moist, improving the throat's natural defenses.
Managing allergies and acid reflux
Adjust your diet, avoiding spicy, acidic, and greasy foods to control acid reflux. Treat allergies with antihistamines or allergen avoidance.
When to See a Doctor
Knowing when to see a doctor is important in treating a sore throat. Timely medical intervention helps treat the exact cause, prevent complications, and shorten recovery time.
Persistent sore throat
A sore throat lasting more than 7–10 days indicates chronic inflammation or an uncontrolled infection. In this case, you should see an ENT specialist to determine the cause.
Severe swelling or breathing difficulty
Swelling of the throat or tonsils that narrows the airway, accompanied by difficulty swallowing and wheezing, is an emergency. Your doctor may prescribe aggressive medical treatment or surgical intervention.
Recurrent infections
Recurrent sore throat episodes several times a year indicate a weakened immune system or the presence of an underlying medical condition, such as chronic tonsillitis and gastroesophageal reflux. Treating the underlying cause helps limit recurrence.
Other red flags
Prolonged high fever, hard neck lymph nodes, blood in the sputum, or unusually rapid weight loss are warning signs of a serious illness that requires a thorough evaluation.
