Is It Normal for One Tonsil to Remain Enlarged After Infection?

Unilateral tonsillar enlargement?

Hello, Doctor.
About two weeks ago, I was diagnosed with acute tonsillitis.
After taking antibiotics for about 9 days, I no longer have any symptoms.
However, my right tonsil, although reduced in swelling, is still slightly larger than before (it was originally slightly larger than the left side).
I would like to ask if this is normal.
Currently, I only occasionally feel a slight sensation in that area, but I have no other symptoms, and I do not feel any foreign body sensation when swallowing.

Hello, the tonsils on both sides may not be the same size; however, if there are concerns, it is still advisable to consult an otolaryngologist for further examination to rule out the possibility of a tonsillar tumor.

More Info

It is not uncommon for one tonsil to remain enlarged after an infection, such as acute tonsillitis. When you experience tonsillitis, the tonsils can become inflamed and swollen as they work to fight off the infection. Even after the symptoms have resolved and you have completed a course of antibiotics, it is possible for one tonsil to remain slightly enlarged for a period of time. This can be due to residual inflammation or the tonsil's response to the previous infection.

In your case, since you mentioned that your right tonsil was slightly larger than the left even before the infection, it is possible that this asymmetry is a normal anatomical variation for you. The fact that you are no longer experiencing significant symptoms, such as pain or difficulty swallowing, is a positive sign. The sensation of something being "stuck" or "kicky" in that area could be due to residual swelling or irritation, but it is generally not a cause for concern if it is not accompanied by other symptoms like fever, severe pain, or difficulty swallowing.

However, it is important to monitor the situation. If the enlargement persists for an extended period, or if you start to experience new symptoms such as pain, difficulty swallowing, or fever, it would be advisable to follow up with your healthcare provider. They may want to perform a physical examination or possibly imaging studies to ensure that there are no underlying issues, such as chronic tonsillitis or other conditions affecting the tonsils.

In some cases, chronic tonsillitis can lead to persistent enlargement of the tonsils, and if this becomes a recurring issue, your doctor may discuss treatment options, which could include surgical removal of the tonsils (tonsillectomy). This is usually considered when the tonsils cause recurrent infections or significant discomfort.

In summary, while it is not unusual for one tonsil to remain slightly enlarged after an infection, it is essential to keep an eye on any changes and consult your healthcare provider if you have concerns or if new symptoms arise. Regular check-ups can help ensure that your throat health remains optimal and that any potential issues are addressed promptly.
