A sore throat is a common symptom that can range from mild irritation to severe pain. While often caused by minor infections, it can also signal more serious conditions. If you've been dealing with a sore throat that just won't go away, or if you have other symptoms that you're concerned about, call or stop in to any IEP Urgent Care location, where we can diagnose and treat many of the common causes, and test for viruses like influenza and COVID-19.
Understanding the possible causes can help determine the best course of action. Here are many common causes of a sore, irritated throat to be aware of:
​
Common Causes of a Sore Throat
​
Viral Infections
The most frequent cause of a sore throat is a viral infection, such as the common cold, flu, or COVID-19.
Symptoms often include coughing, congestion, fever, and fatigue.
These infections usually resolve on their own with rest and fluids.Â
Bacterial Infections
Strep throat is a bacterial infection caused by Streptococcus bacteria.
Symptoms often include severe throat pain, swollen tonsils, white patches in the throat, and fever.
Strep requires antibiotic treatment to prevent complications like rheumatic fever.Â
Allergies
Seasonal allergies to pollen, dust, or pet dander can cause throat irritation due to postnasal drip.
Unlike infections, allergies don’t cause fever but may lead to itchy eyes and sneezing.Â
Irritants and Environmental Factors
Smoking, air pollution, dry air, and chemicals can irritate the throat.
Acid reflux (GERD) can also cause a sore throat due to stomach acid irritating the esophagus.Â
Tonsillitis and Other Conditions
Inflamed tonsils (tonsillitis) can cause pain, swelling, and difficulty swallowing.
Mononucleosis (mono) and other viral infections may also present with throat pain and fatigue.Â
When to Seek Medical Attention
​
Most sore throats improve within a few days, but call or visit IEP Urgent Care or your doctor if you experience:
Severe or persistent throat pain (longer than 10 days)
Difficulty breathing or swallowing
High fever
White patches, swelling, or pus in the throat
Enlarged lymph nodes or skin rash
​
Treatment and Prevention
​
Rest, hydration, and throat lozenges can ease discomfort.
Pain relievers like ibuprofen can help with swelling and pain.
Avoid smoking and stay hydrated to prevent irritation.
Frequent handwashing can reduce the risk of infections.
