Pharyngitis is the medical term for a sore throat caused by inflammation of the pharynx, the tube that connects your mouth and nasal passages to your esophagus and larynx. It’s usually the result of a viral or bacterial infection and leads to symptoms such as pain, redness, swelling, and difficulty swallowing.
The most common bacterial cause is Group A Streptococcus (strep throat), while most other cases are viral. Pharyngitis can affect anyone and often develops after exposure to someone with a cold, flu, or throat infection.
In simple terms, pharyngitis = sore, inflamed throat, often caused by germs that irritate the lining of your throat.

Pharyngitis occurs when the tissues in the back of the throat, known as the pharynx, become inflamed and swollen. This area sits between your tonsils and your voice box (larynx) and plays an important role in breathing and swallowing.
Most sore throats develop from viral infections, such as the common cold, flu, coxsackie virus, or mononucleosis (mono). These viral cases usually clear up on their own within a few days.
In some cases, bacteria can cause pharyngitis. The most frequent bacterial infection is strep throat, caused by Group A Streptococcus. Less commonly, sexually transmitted infections like gonorrhea and chlamydia can also lead to a sore throat.
Pharyngitis tends to be more common during cold weather months, when people spend more time indoors and infections spread easily among family members and close contacts.
The main symptom is a sore throat.
Other symptoms may include:
Your healthcare provider will begin with a physical examination, carefully checking your throat for redness, swelling, or white patches.
To determine the cause, your provider may perform a rapid strep test or take a throat culture to check for Group A Streptococcus bacteria. Depending on your symptoms and medical history, additional lab tests may be ordered to rule out other infections or underlying conditions.
If you’ve been exposed to HIV and are experiencing a sore throat, it’s important to get tested for HIV as part of your evaluation. Early testing ensures proper care and peace of mind.

If your sore throat lasts more than a few days, or you experience fever, swollen glands, or trouble swallowing, schedule an appointment at Medex Diagnostic & Treatment Center. Our team provides same-day appointments and comprehensive testing to quickly identify the cause and deliver the right treatment.
Complications may include:
Ever had a sore throat so painful it feels like you’ve swallowed sandpaper? That burning, scratchy sensation can make even a sip of water uncomfortable. What you’re likely dealing with is pharyngitis — the medical term for inflammation of the pharynx, the area in the back of your throat between your tonsils and voice box.
When viruses or bacteria invade this area, they can make your throat red, swollen, and tender. Depending on what caused it, pharyngitis may go away on its own or require treatment.

The most frequent culprit behind a sore throat is an infection, either viral or bacterial.
If your throat looks red, swollen, or covered with white spots, it’s time to see a doctor. You might also notice:
Your provider may perform a quick throat swab test (called a throat culture) to check for strep bacteria. If it’s positive, antibiotics can clear the infection and help prevent complications.
If your sore throat is viral, the best medicine is rest and comfort care while your body fights it off.
While you recover, try these home remedies to ease the pain:
If your throat feels extremely raw, avoid spicy or acidic foods and focus on gentle hydration — water, herbal teas, or broths.
Most sore throats clear up in a few days. But call your doctor if you experience:
Stay home until you’ve been fever-free for at least 24 hours to avoid spreading germs to others.
A sore throat can be caused by many things, from a mild viral infection to strep throat that needs antibiotics. While most cases improve with rest, fluids, and simple care, a doctor’s visit is the safest way to confirm the cause, especially if symptoms worsen.
