Persistent Cough After Cold: When to Seek ENT Specialist Help - Otolaryngology

The cough will not improve?


On January 4th, I caught a cold and went to the clinic for medication on the same day.
At that time, I didn't have much of a cough, just a fever and a sore throat.
After two rounds of treatment, all other symptoms improved, but the cough persisted and worsened until early February, when I was still coughing and occasionally experiencing sore throat.
During this period, I continued to visit the clinic for medication and later went to a local small hospital to see a pulmonologist.
The X-ray results showed no issues, and the doctor prescribed some bronchodilators and medications to control nasal discharge, but there was no improvement after completing the course.
I would like to know which specialty I should continue to consult regarding this matter.
Previously, during a consultation, the doctor mentioned the possibility of chronic rhinitis (at that time, I did not have a cough).
I thought it was just mild post-nasal drip, so I did not pursue further treatment.
Additionally, I have noticed a significant difference in airflow between my nostrils (which I have had since childhood), and I often experience a sensation of blockage during exercise, similar to tinnitus, which occurs more on the side with the smaller airflow.
I'm not sure if this is related.

Persistent cough following a cold can be a frustrating and distressing experience, especially when it lingers for weeks or even months. In your case, it seems that after initially experiencing symptoms of a cold, including fever and sore throat, the cough has persisted and worsened over time. Given your history and the treatments you've already undergone, it’s essential to consider several factors that could be contributing to your ongoing symptoms.

Firstly, it’s important to understand that a cough can persist after a viral infection due to several reasons. One common cause is post-viral cough, which occurs when the airways remain sensitive and reactive even after the initial infection has resolved. This sensitivity can lead to a prolonged cough, sometimes lasting several weeks. Additionally, conditions such as post-nasal drip, where mucus from the sinuses drips down the back of the throat, can also trigger coughing. This is particularly relevant in your case, as you mentioned experiencing nasal congestion and potential chronic rhinitis.

Given that you have already consulted with a primary care physician and a pulmonologist without significant improvement, it may be time to consider seeing an Ear, Nose, and Throat (ENT) specialist. An ENT can provide a more comprehensive evaluation of your nasal passages and throat, which may be contributing to your cough. They can perform a thorough examination, including a nasal endoscopy, to assess for any structural issues, such as nasal polyps or chronic sinusitis, that could be causing your symptoms.

In addition to seeking an ENT evaluation, there are several self-care strategies you can implement to help alleviate your cough. Staying well-hydrated is crucial, as it helps thin mucus and can reduce throat irritation. Using a humidifier in your home, especially in your bedroom at night, can also help keep your airways moist and may reduce coughing. Over-the-counter medications, such as antihistamines or decongestants, may provide relief if your cough is related to post-nasal drip or nasal congestion.

Furthermore, you mentioned experiencing a difference in airflow between your nostrils and a sensation of ear fullness or tinnitus. This could indicate underlying nasal obstruction or Eustachian tube dysfunction, which an ENT specialist can evaluate. Addressing these issues may not only help with your cough but also improve your overall breathing and comfort.

In summary, persistent cough after a cold can be multifactorial, and given your ongoing symptoms, it is advisable to seek further evaluation from an ENT specialist. They can help identify any underlying issues that may be contributing to your cough and provide targeted treatment options. In the meantime, focus on hydration, humidity, and possibly over-the-counter medications to manage your symptoms. If your cough worsens or you develop new symptoms, don’t hesitate to seek medical attention promptly.
