Tonsillar enlargement (without fever, painless)


Dear Doctor,
At the beginning of June, I felt a sore throat and dizziness, so I went to see a doctor and took medication for three days, after which my throat pain subsided.
However, I continued to feel dizzy for three weeks.
At the end of June, I noticed something unusual with my throat and sought medical attention again, where I discovered that my tonsils were swollen on both sides and had white discharge.
I did not have any cold symptoms, just dizziness and a strange feeling in my throat, with white discharge on my tonsils, but they were not painful.
The clinic doctor mentioned that it was just discharge and not pus.

At the beginning of July, I started a 10-day course of antibiotics.
Although the white discharge has disappeared, my tonsils have not returned to normal after a month (they are completely painless, but I feel a strange sensation and increased heat when swallowing saliva).
Is it possible for tonsillitis and swelling to take a long time to resolve? I have seen information online about tonsil cancer being associated with prolonged swelling, which has made me a bit worried.
I have visited the clinic three times in between for medication, and the doctor said there is no need to worry.

Dr. Zheng Jueyi reply Otolaryngology


Hello: The size of the tonsils varies from person to person.
They can become enlarged during inflammation or infection and will decrease in size once the infection improves.
If there are no significant pain, ulcers, or discharge, it is often a case of benign tonsillar enlargement.
If you have concerns, you may visit an otolaryngology clinic for further evaluation.
Wishing you safety and health.
Sincerely, Dr.
Jue-Yi Cheng, Director of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

Persistent swollen tonsils without accompanying pain or fever can be concerning, especially when symptoms linger for an extended period. Your experience of having swollen tonsils with white secretions, without the typical symptoms of a cold or flu, raises several important considerations.

Firstly, it’s essential to understand that swollen tonsils, or tonsillitis, can occur due to various reasons. In your case, the absence of pain and fever suggests that the inflammation may not be due to a typical bacterial infection, which often presents with these symptoms. Instead, your condition could be attributed to several factors, including chronic inflammation, allergies, or even viral infections that do not always manifest with the classic symptoms.

The presence of white secretions on the tonsils can indicate the presence of debris, dead cells, or even a mild infection. In some cases, these secretions can be a result of chronic tonsillitis, where the tonsils remain enlarged due to ongoing irritation or infection, even if the acute symptoms have resolved. It is also possible that the tonsils are reacting to allergens or irritants in your environment, leading to persistent swelling without significant pain.

Regarding your concern about the duration of the swelling, it is not uncommon for tonsils to remain enlarged for weeks or even months after an infection has resolved, especially if there has been a history of recurrent tonsillitis. The tonsils can take time to return to their normal size, particularly if they have been inflamed repeatedly. However, if the swelling persists for an extended period, it is crucial to monitor the situation closely.

Your mention of concerns regarding tonsil cancer is understandable, especially with the internet providing a plethora of information that can sometimes lead to anxiety. While persistent swelling can be a symptom of more serious conditions, it is important to remember that the vast majority of cases of swollen tonsils are benign and related to infections or chronic inflammation. Tonsil cancer is relatively rare, and other symptoms such as significant pain, difficulty swallowing, or changes in voice typically accompany it. If your doctor has assessed your condition and indicated that there is no immediate concern, it is likely that they are monitoring for any alarming signs.

That said, if you continue to experience discomfort or if the swelling does not subside, it may be worthwhile to seek a second opinion or consult an ear, nose, and throat (ENT) specialist. They can perform a thorough examination, possibly including imaging studies or a biopsy if deemed necessary, to rule out any serious conditions.

In the meantime, maintaining good hydration, avoiding irritants such as smoke or strong odors, and possibly using saline gargles may help alleviate some of the discomfort associated with the swollen tonsils. If you have any underlying allergies, addressing those may also contribute to reducing the inflammation.

In summary, while persistent swollen tonsils without pain or fever can be concerning, they are often due to benign causes. It is essential to continue monitoring your symptoms and maintain open communication with your healthcare provider to ensure that any changes are promptly addressed. If you have any further questions or if your symptoms change, do not hesitate to seek medical advice.
