Allergies: Chronic Cough and Chest Tightness Explained - Pulmonology

Understanding your symptoms and their potential connection to allergies and asthma is crucial for effective management and treatment. Based on your description, it seems you are experiencing a combination of allergic rhinitis and possible asthma-like symptoms. Let’s break down your symptoms and explore their implications.


Allergic Rhinitis and Its Symptoms
Allergic rhinitis, commonly known as hay fever, occurs when your immune system overreacts to allergens in the air, such as pollen, dust mites, or pet dander. Symptoms typically include:
- Nasal congestion
- Sneezing
- Itchy or runny nose
- Postnasal drip, which can lead to coughing
In your case, you mentioned that you experience nasal congestion, particularly when lying down or during certain activities like cleaning. This suggests that your nasal passages are sensitive to allergens, which is characteristic of allergic rhinitis. The fact that you primarily breathe through your mouth due to nasal congestion can exacerbate your symptoms, leading to a dry throat and potentially contributing to your chronic cough.


Chronic Cough and Chest Tightness
Your chronic cough, especially when triggered by cold air or specific environmental factors (like incense smoke), is concerning. Chronic cough can be a symptom of asthma, particularly if it occurs without an accompanying cold or infection. Asthma is characterized by inflammation and narrowing of the airways, leading to symptoms such as:
- Wheezing
- Shortness of breath
- Chest tightness
- Coughing, especially at night or early in the morning
Given your family history of asthma and your previous diagnosis, it is possible that you may have asthma that has not been formally diagnosed or treated. The sensation of chest tightness and difficulty taking deep breaths, as you described, are classic signs of asthma exacerbation.


Physical Activity and Breathing Difficulties
Your experience of feeling breathless during physical activities, such as long-distance running, is another indicator of potential asthma. Individuals with asthma often find that exercise can trigger symptoms, particularly if they are exposed to cold air or allergens during physical exertion. The fact that you can run for only a short duration before feeling out of breath suggests that your airways may be constricting, making it difficult for you to get enough air.


Thyroid Function and Its Impact
You mentioned having hyperthyroidism (甲亢), which can also contribute to feelings of anxiety and shortness of breath. Hyperthyroidism can increase your metabolism and heart rate, potentially leading to symptoms that mimic or exacerbate asthma. It’s essential to ensure that your thyroid levels are well-controlled, as this can significantly impact your overall respiratory health.


Recommendations
1. Consult a Specialist: Given your symptoms and history, it would be beneficial to see an allergist or a pulmonologist. They can perform specific tests, such as pulmonary function tests, to assess your lung function and determine if asthma is present.

2. Allergy Testing: Consider undergoing allergy testing to identify specific triggers. This can help you avoid allergens that exacerbate your symptoms.

3. Asthma Management Plan: If asthma is diagnosed, your healthcare provider may recommend an asthma action plan, which could include the use of inhalers (both rescue and maintenance medications) to help manage your symptoms effectively.

4. Environmental Control: Implementing measures to reduce exposure to allergens in your home, such as using air purifiers, keeping windows closed during high pollen seasons, and avoiding smoking or incense, can help alleviate your symptoms.

5. Regular Monitoring: Keep track of your symptoms, especially during physical activities or exposure to known triggers. This information can be invaluable for your healthcare provider in managing your condition.

In conclusion, your symptoms suggest a potential overlap between allergic rhinitis and asthma. A thorough evaluation by a healthcare professional is essential to confirm a diagnosis and develop an appropriate treatment plan. With the right management, you can significantly improve your quality of life and reduce the impact of these conditions on your daily activities.
