Unilateral tonsillar enlargement?


I have had unilateral tonsil enlargement for two weeks.
Initially, there was white discharge and pain when swallowing saliva, but I did not have a fever.
I consulted a doctor who said it was a bacterial infection and prescribed antibiotics.
The discharge has resolved, but the left tonsil is still swollen, although it does not hurt, and I can swallow normally.
What should I do now?

Hello: If there are no obvious symptoms, it is normal for the size of the tonsils to vary slightly from side to side.
However, if there is persistent pain or ulcers, a follow-up medical examination is necessary.
Wishing you peace and health.

Persistent unilateral tonsil swelling can be concerning, especially when it lasts for two weeks without significant pain or fever. Given your situation, it’s important to consider a few key points regarding the potential causes and next steps.

Initially, the presence of white discharge and pain indicated a bacterial infection, which is common in cases of tonsillitis. The antibiotic treatment you received likely addressed the bacterial component, leading to the resolution of the discharge and pain. However, the lingering swelling of the tonsil could be due to several factors.

1. Post-Infectious Inflammation: After an infection, it is not uncommon for the tonsils to remain swollen for some time as the body continues to heal. This can take several weeks, and if there are no other symptoms (like pain, fever, or difficulty swallowing), it may simply be a sign of ongoing recovery.

2. Chronic Tonsillitis: If you have a history of recurrent tonsillitis, the swelling could indicate chronic inflammation. In such cases, the tonsils may not return to their normal size even after an infection has resolved.

3. Abscess Formation: Although less likely given your current symptoms, a peritonsillar abscess can develop following a bacterial infection. This typically presents with severe pain, difficulty swallowing, and sometimes fever. If you experience any of these symptoms, seek medical attention immediately.

4. Other Conditions: Rarely, unilateral tonsil swelling can be a sign of more serious conditions, such as a tumor or lymphoma. While these are less common, they should be considered, especially if the swelling persists without improvement.


Next Steps
1. Follow-Up Appointment: Since your symptoms have changed but the swelling persists, it would be prudent to schedule a follow-up appointment with your healthcare provider. They may perform a physical examination and possibly recommend imaging studies, such as an ultrasound or CT scan, to evaluate the tonsil further.

2. Observation: If you are asymptomatic (no pain, fever, or swallowing difficulties), your doctor may suggest a period of observation. Sometimes, the swelling will resolve on its own as the inflammation decreases.

3. Consider Referral: If the swelling does not improve or if you develop new symptoms, your doctor may refer you to an ENT (ear, nose, and throat) specialist for further evaluation. They can provide a more detailed examination and determine if any additional interventions are necessary.

4. Maintain Good Oral Hygiene: Keeping your throat and mouth clean can help prevent further infections. Gargling with warm salt water may provide some relief and promote healing.

5. Stay Hydrated: Drinking plenty of fluids can help soothe your throat and support your immune system.

In summary, while persistent unilateral tonsil swelling can be concerning, it is often due to post-infectious inflammation or chronic tonsillitis. Monitoring your symptoms and following up with your healthcare provider is essential to ensure that any underlying issues are addressed. If you notice any changes or new symptoms, do not hesitate to seek medical advice.
