What are pharyngitis and tonsillitis?
Pharyngitis and tonsillitis are throat infections that cause inflammation. If the tonsils are mainly affected, it’s called tonsillitis. If the throat is mainly affected, it’s called pharyngitis. If you have both, it’s called pharyngotonsillitis. These infections are spread by close contact with others. Most cases happen during the winter or colder months.
What causes pharyngitis and tonsillitis?
There are many causes of throat infections. Viruses are the most common cause and antibiotics won’t help. Causes of throat infections include:
Viruses (most common)
Bacteria such as strep
What are the symptoms of pharyngitis and tonsillitis?
The symptoms of pharyngitis and tonsillitis depend greatly on what’s causing it. For some people, symptoms may start quickly. For others, symptoms start slowly. The most common symptoms of pharyngitis and tonsillitis are:
Fever (low-grade or high-grade)
Loss in appetite
Not feeling well
Redness or drainage in the throat
The symptoms of pharyngitis and tonsillitis may look like other health conditions or problems. Always check with your healthcare provider for a diagnosis.
How are pharyngitis and tonsillitis diagnosed?
In most cases, it’s hard to tell the difference between a viral sore throat and a strep throat based on a physical exam. But it’s important to know if the sore throat is caused by strep bacteria. Antibiotics are needed for strep infections.
As a result, most people with the above symptoms will get a strep test and throat culture to find out if it’s an infection caused by strep. This will be done using a throat swab in the healthcare provider’s office.
Quick tests, called rapid strep tests, may be done. This may immediately show as positive for strep so antibiotics can be started. If it’s negative, part of the throat swab will be kept for a throat culture. It will help identify strep in 2 to 3 days if present. Your healthcare provider will discuss the treatment plan with you based on the findings.
How are pharyngitis and tonsillitis treated?
Treatment will depend on your symptoms, age, and general health. It will also depend on how bad the condition is.
If bacteria are not the cause of the infection, the treatment is often more for comfort. Antibiotics will not help treat viral sore throats. Treatment may include:
Acetaminophen, naproxen, or ibuprofen for pain and fever. (Talk with your healthcare provider before using these medicines if you have chronic liver or kidney disease, or have ever had a stomach ulcer or gastrointestinal bleeding)
Drinking more fluids
Gargling with warm saltwater
Antibiotics are prescribed if the infection is bacterial.
What are possible complications of pharyngitis and tonsillitis?
Most cases of pharyngitis and tonsillitis will run their course without any problems. But if the disease is caused by strep, rare complications can happen. These include rheumatic fever, rheumatic heart disease, and kidney disease. Treatment with antibiotics can prevent these complications. In rare cases, a pocket of infection (peritonsillar abscess) can develop in the tissues around the tonsils. This may need to be drained by your healthcare provider.
When should I call my healthcare provider?
If a sore throat includes increasing pain with swallowing or mild neck swelling, see a healthcare provider right away.
Drooling or difficulty swallowing saliva
Increasing neck swelling
Shortness of breath, trouble breathing, or a whistling noise in your throat with breathing
