A peritonsillar abscess is one of the most severe complications that can occur from a common sore throat. Symptoms of simple tonsillitis can escalate to an abscess in throat tissue that can block your airway, leave you dangerously dehydrated and become a serious threat to surrounding structures if untreated.
If you know what to look for and when it is time to seek medical attention, you can save yourself or your child from a much more serious experience.
What Is a Peritonsillar Abscess?
A peritonsillar abscess is one of the most serious forms of a throat infection and requires prompt emergency evaluation. It is usually referred to as a tonsillar abscess and it is a pus pocket that develops between the tonsil and the wall of the throat. It forms when a bacterial infection passes beyond the tonsil and is trapped in the surrounding space causing pressure to build up.
It’s also known as quinsy, an older term still used by many physicians today.
Peritonsillar Abscess vs Tonsillitis
Tonsillitis is swelling of the tonsils caused by a virus or bacteria (such as strep). Most cases heal on their own with over-the-counter medication, rest, fluids and sometimes antibiotics. When the infection does not resolve and spreads deeper into the tissues, the sore throat turns into a tonsil abscess in the days that follow.
Is a Peritonsillar Abscess the Same as a Throat Abscess?
Not exactly. The larger term is “throat abscess” and the smaller term is “peritonsillar abscess”, which is the pocket next to the tonsil. Below is a comparison of the related conditions.
Tonsillitis occurs when the tonsils become swollen and is usually not very serious. Usually, it is treated with antibiotics.
Peritonsillar Abscess: Peritonsillar Abscess is a swelling around the tonsil and is classified as a high-severity case. Treatment consists of drainage and antibiotics.
A deep neck abscess involves the neck spaces and is considered a medical emergency. It requires surgery along with IV antibiotics.
Peritonsillar Abscess Symptoms
Typical symptoms of most people are a severe sore throat, typically worse on one side, fever, swollen tonsil, ear pain and painful swallowing. Individuals delay their care for these peritonsillar abscess symptoms because they are similar to those of regular tonsillitis.
Advanced Signs of Peritonsillar Abscess
As the infection progresses, more distinct signs of peritonsillar abscess appear:
- Trouble opening the mouth (trismus)
- Muffled voice, often a “hot potato” sound
- Drooling
- Swollen lymph nodes
- Uvula deviation to one side
- Bad breath and visible neck swelling
Symptoms That Require Immediate Emergency Care
Some symptoms mean this is an ENT emergency. Get to the emergency room right away for:
- Trouble breathing
- Inability to swallow saliva
- Rapid neck swelling
- Severe dehydration or confusion
- High fever and chills
Quick Emergency Checklist: If patients have difficulty breathing, are unable to swallow saliva or if your sore throat is accompanied by a high fever, difficulty swallowing, or breathing problems, you should visit the ER immediately.
What Causes a Peritonsillar Abscess?
Normally, peritonsillar abscess typically is caused by Streptococcus, Staphylococcus or anaerobic bacteria that grow in tissues with little oxygen. More than one type is usually involved and thus the treatment required involves targeted antibiotics.
How Untreated Tonsillitis Leads to an Abscess
Tonsillitis first, bacteria further invade tissue rather than remain localized. Pus gets trapped because it cannot drain out of the body naturally and eventually swelling progresses until it becomes a more serious tonsillitis complication. Untreated strep throat or bacterial tonsillitis can spread deeper into surrounding tissues, eventually leading to a peritonsillar abscess.
Risk Factors
Your risk is higher if you have recurrent tonsillitis, smoke, have gum disease, have a compromised immune system and you don’t seek treatment for an emergency throat infection.
Can You Get a Tonsil Abscess Without Tonsillitis?
Yes. Sometimes, a tonsil abscess will occur due to dental infections or tonsil stones and not due to a previous episode of tonsillitis, so it’s important to seek help for one-sided throat pain even if there is no previous case of tonsillitis.
Is Peritonsillar Abscess Dangerous?
Is peritonsillar abscess serious? Yes, particularly if not treated. It’s located close to the airway, which may cause swelling and make it hard to breathe and infection can travel to nearby structures.
The potential complications are airway blockage, deep neck infection, sepsis, aspiration and spread into the chest. The symptoms can progress to trismus and drooling in 24 to 72 hours and to severe trismus and drooling in a few days.
Peritonsillar Abscess Antibiotics
Amoxicillin-clavulanate, clindamycin or penicillin combinations are commonly used antibiotics to treat peritonsillar abscesses depending on the suspected bacteria.
IV antibiotics are used in more severe cases and will work more quickly and are combined with drainage in the ER. Oral antibiotics take longer to work and are more appropriate for less severe infections or for post hospital management.
Oral antibiotics may be administered after IV antibiotics are used in the ER, particularly when drainage is performed and continues for completion of the recovery process at home. Patients should feel better within 48-72 hours, but if treatment is terminated too early, then surviving bacteria can multiply, increasing the likelihood of the abscess returning.
When Should You Go to the Emergency Room?
Seek immediate medical attention for difficulty breathing, inability to swallow saliva, severe neck swelling or fever and confusion.
An emergency physician will then inspect your throat and airway, possibly order a CT scan to confirm the presence of an abscess and will either perform needle aspiration or incision and drainage to remove the pus during a visit. IV antibiotics are then administered, monitored before discharge with oral medication and followed up.
Peritonsillar Abscess Treatment in San Antonio
Peritonsillar abscess treatment in San Antonio should not be postponed If you need abscess treatment in San Antonio, RapidCare Emergency provides immediate evaluation, imaging, IV antibiotics, and emergency drainage for severe infections, including peritonsillar abscesses. 343 W Bitters Rd, San Antonio, TX 78216, RapidCare Emergency Room is an ER that has no appointment hours and is available 24 hours a day.
On-site CT imaging verifies the size and location of the abscess and lab testing is done to identify if there is an infection and dehydration and IV antibiotics are given immediately to control symptoms. Board-certified doctors can drain the abscesses and keep an eye on your airway at the same time, without having to leave the premises, reducing the risk of the infection spreading deeper into the neck space or the chest.
Tips to Prevent Future Tonsil and Throat Abscesses
- Treat sore throats early, don’t wait out a worsening, one-sided sore throat with fever.
- Complete every antibiotic course, even after you feel better.
- Maintain good oral hygiene through regular brushing, flossing and checkups.
- Stop smoking, which irritates throat tissue and weakens infection defenses.
- Stay hydrated to support healthier throat tissue and immune response.
Common Myths About Peritonsillar Abscess
- “It will drain on its own”: Minor cases occasionally resolve, but most need professional abscess drainage to fully clear the infection.
- “Antibiotics always cure it”: Medication alone often isn’t enough once an abscess has formed; drainage is usually needed too.
- “It’s just a bad sore throat”: As a strep throat complication, it can progress to airway problems within days.
- “Only children get quinsy”: It is most commonly found in teens and young adults, but can occur in persons of any age.
Conclusion
Watch for one-sided sore throat, trismus, drooling and muffled voice. Go to the RapidCare emergency room right away if there’s difficulty breathing, trouble swallowing saliva or rapid swelling of the neck. The majority of patients will improve gradually over a period of one to two weeks.
A peritonsillar abscess may rapidly progress to a serious condition. Most patients will make a full recovery if it is diagnosed and treated promptly with no permanent complications.
