Why Do I Have Sores in My Throat?

Sores in the throat, presenting as painful spots, ulcers, or white patches, signal a break in the mucous membrane lining the pharynx or esophagus. This common symptom indicates underlying inflammation or tissue damage. The causes are diverse, ranging from contagious pathogens to chronic physical and chemical irritation.

Common Causes Stemming from Infections

Infectious agents, both viral and bacterial, are the most frequent causes of throat sores. Viral infections often produce distinct, self-limiting lesions. For example, Herpes Simplex Virus type 1 (HSV-1) can cause painful blisters and ulcers on the soft palate and throat. Coxsackievirus, which causes Hand-Foot-and-Mouth Disease, leads to Herpangina, characterized by small, painful ulcers on the tonsils and soft palate.

Other viral infections, such as Epstein-Barr virus (Mononucleosis), cause severe throat inflammation. This inflammation may manifest as thick, whitish-yellow patches or exudate on the tonsils, which mimic true sores. Bacterial infections like Strep throat, caused by Streptococcus pyogenes, often present with white patches or streaks of pus on the tonsils. Unlike viral infections, bacterial causes typically lack generalized cold symptoms like a cough or runny nose.

Physical Irritants and Chronic Non-Infectious Factors

Throat sores can arise from non-pathogenic sources involving physical or chemical irritation. Gastroesophageal Reflux Disease (GERD) is a common cause where acidic stomach contents flow backward, irritating the esophagus and lower pharynx. This repeated exposure causes inflammation (esophagitis) and can create open sores or ulcers distinct from infections.

Physical injury also causes throat lesions, such as scrapes from swallowing sharp foods or thermal burns from excessively hot liquids. Chronic habits like smoking and excessive alcohol use chemically irritate the tissue. This irritation weakens the mucosal barrier and can lead to persistent inflammation or ulceration over time.

When to Seek Medical Attention

While many throat sores heal naturally, certain signs require prompt medical evaluation. Seek immediate care if you experience severe difficulty breathing or swallowing, or if you begin to drool excessively, which may indicate a blockage or deep infection. Other urgent signs include a persistent fever over 102°F (39°C) or severe pain limited to one side of the throat.

Consult a healthcare provider if throat sores persist without improvement for seven to ten days. Sores that reoccur frequently or are painless but do not heal should also be checked. These persistent or unusual lesions may require diagnostic testing to rule out more serious underlying conditions, such as autoimmune disorders.

Immediate Relief and Symptom Management

While awaiting a diagnosis, several strategies can help manage pain and discomfort. Over-the-counter pain relievers, such as acetaminophen or ibuprofen, effectively reduce pain, and ibuprofen also offers anti-inflammatory benefits. Topical treatments, including numbing lozenges or throat sprays containing benzocaine or menthol, can temporarily alleviate localized pain, especially before meals.

Symptom management focuses on protecting the irritated tissue from further harm. Gargling with a warm saltwater solution can help soothe the throat lining and reduce inflammation. Consume soft, mild foods and cool liquids, such as ice chips or popsicles, while strictly avoiding acidic, spicy, or hot items that can sting the exposed tissue. Adequate hydration is necessary to keep the throat moist and assist the body’s natural healing process.
