Tonsil follow-up appointments: 4 times?


Dear Doctor: About a month ago, I had a cold and my tonsils became swollen on both sides, with the left side being larger.
There is white discharge on the top.
My tonsils do not hurt; I just feel something unusual in my throat.
I have taken medication and returned for follow-ups three times.
The swelling has decreased a bit, and the discharge is gone.
During my fourth visit, the doctor said that my tonsils have likely stabilized at their current size and will not return to their original size.
Doctor, my tonsils are swollen but do not hurt.
Does this indicate a more serious problem? I found some information online stating that painless swelling could be malignant, which makes me very anxious.
(The clinic doctor said that the absence of pain is a good sign.) He mentioned that my tonsils are likely to remain at their current size and will not completely shrink back.
Is this considered benign enlargement? Is this normal? Thank you.

Hello: If there is no obvious ulcer pain and the examination by the physician shows no significant abnormalities, it is mostly benign tonsillar enlargement.
You may observe it yourself or return for regular follow-up visits.
Wishing you peace and health.
Sincerely, Dr.
Jue-Yi Cheng, Director of the Department of Otolaryngology, Taoyuan General Hospital, Ministry of Health and Welfare.

More Info


Tonsil enlargement, or tonsillar hypertrophy, can be a common occurrence, especially following infections such as viral or bacterial illnesses. Your situation, where you experienced a cold followed by bilateral tonsil enlargement, is not uncommon. The presence of white discharge on the tonsils can indicate a previous infection, often associated with viral or bacterial tonsillitis.
From your description, it seems that your tonsils have not been painful, which is a positive sign. Painful tonsils often suggest an active infection or inflammation, while non-painful enlargement can sometimes indicate chronic changes or residual effects from a past infection. Your doctor’s assessment that your tonsils may have reached a new baseline size is also consistent with what can happen after an episode of tonsillitis.
In terms of when to worry about tonsil enlargement, there are several factors to consider:
1. Duration: If the enlargement persists for an extended period (typically more than a few weeks) without improvement, it may warrant further investigation.

2. Associated Symptoms: While pain is a significant indicator of infection, other symptoms such as difficulty swallowing, breathing difficulties, or significant changes in voice should be taken seriously. If you experience any of these, it’s essential to seek medical advice.

3. Changes in Appearance: If the tonsils develop unusual features, such as hard masses, persistent white patches, or significant asymmetry, these could be signs of a more serious condition.

4. Systemic Symptoms: If you experience fever, night sweats, unexplained weight loss, or fatigue, these could be signs of a more serious underlying condition that requires further evaluation.

Your concern about the potential for malignancy due to the absence of pain is understandable, especially with the wealth of information available online. However, it’s important to remember that many benign conditions can cause tonsil enlargement without pain. Your doctor’s reassurance that the lack of pain is a good sign is generally accurate, as many serious conditions often present with pain or other systemic symptoms.

In your case, since your doctor has indicated that the tonsils may not return to their original size and has described the enlargement as likely benign, it’s reasonable to consider this a normal variant following an infection. However, if you remain concerned or if any new symptoms develop, it would be prudent to follow up with your healthcare provider for further evaluation.
In summary, while tonsil enlargement can be concerning, especially when accompanied by unusual symptoms, your current situation appears to be stable. Maintaining regular follow-ups with your healthcare provider and monitoring for any changes in your condition is the best course of action. If you have any lingering concerns, don’t hesitate to seek a second opinion or further testing to ensure peace of mind.
