Persistent Cough for Two Months: Possible Causes and Solutions

Coughing for a long time?

I have been coughing for two months.
It started with a sore throat, and I was coughing up green phlegm.
After seeing a doctor, the uncomfortable symptoms improved, and the phlegm lost its color.
However, the cough has not resolved; I tend to cough more when I talk, and the cough becomes more severe with increased talking.
My throat feels itchy, and when I cough, I expel thicker mucus.
Generally, I don't cough much when I'm not talking, and I don't cough during exercise or running.
I would like to know if this could possibly be related to an abdominal issue, considering I have been coughing for two months.

There are many causes of chronic cough.
If you have already seen an otolaryngologist and ruled out diseases related to that specialty, you may want to consult a gastroenterologist if you have gastroesophageal reflux or chronic stomach pain.
Most importantly, you should schedule an appointment with a pulmonologist for a chest X-ray, and then have the doctor provide a diagnosis.
Wishing you a speedy recovery.

More Info

Persistent cough lasting for two months can be quite concerning, especially when it follows an initial respiratory infection. Based on your description, it seems that your cough began after experiencing symptoms of a cold, including a sore throat and green phlegm. While the initial symptoms improved, the cough has persisted, and you are now experiencing throat irritation and increased coughing when speaking or after physical activity.

There are several potential causes for a persistent cough, especially following a respiratory infection. Here are some possibilities:
1. Post-viral Cough: After a viral infection, it is common for some individuals to experience a lingering cough. This is often due to inflammation in the airways that can take time to resolve. The cough may be exacerbated by talking or physical exertion, as you have noted.

2. Bronchitis: Acute bronchitis can develop after a cold or flu, characterized by inflammation of the bronchial tubes. While you mentioned that the initial symptoms improved, it is possible that bronchitis could still be present, leading to a persistent cough and phlegm production.

3. Asthma or Reactive Airways: Given your history of respiratory issues, including asthma, it is possible that your airways are reacting to the previous infection. This can lead to increased sensitivity and a persistent cough, especially during physical activity or when speaking.

4. Gastroesophageal Reflux Disease (GERD): Sometimes, a cough can be related to acid reflux, where stomach acid irritates the throat and airways. This could explain the throat irritation and cough when talking or after eating.

5. Allergies or Environmental Irritants: Allergens or irritants in your environment could also be contributing to your cough. This is particularly relevant if you are exposed to smoke, dust, or other pollutants.

6. Chronic Sinusitis: If you have sinus issues, post-nasal drip can lead to throat irritation and a persistent cough. This occurs when mucus from the sinuses drips down the back of the throat, triggering a cough reflex.

Given that your cough has persisted for two months, it is important to consult with a healthcare provider for a thorough evaluation. They may recommend diagnostic tests such as a chest X-ray or pulmonary function tests to rule out conditions like asthma or chronic bronchitis.
In the meantime, here are some strategies that may help alleviate your symptoms:
- Stay Hydrated: Drinking plenty of fluids can help thin mucus and soothe your throat.

- Humidify the Air: Using a humidifier can add moisture to the air, which may help ease coughing.

- Avoid Irritants: Stay away from smoke, strong odors, and allergens that may trigger your cough.

- Consider Over-the-Counter Remedies: Cough suppressants or expectorants may provide temporary relief, but consult with a healthcare provider before starting any new medication.

- Monitor Your Symptoms: Keep track of any changes in your cough, such as the presence of blood, changes in the color of phlegm, or any new symptoms like fever or shortness of breath.

In summary, while a persistent cough can be caused by various factors, it is essential to seek medical advice to determine the underlying cause and appropriate treatment. Your healthcare provider will be able to guide you through the diagnostic process and help you find relief from your symptoms.
