Chronic cough


Hello, doctor.
I have been experiencing a persistent dry cough for 3-4 years, often feeling the need to clear my throat.
Sometimes, I feel a bit of difficulty breathing.
In recent months, I have occasionally felt pain on the left side of my chest, which feels more like a tight pain.
There have been one or two instances where I woke up at night feeling very tight and in pain while lying on my side.
I also experience occasional pain.
I would like to ask if this could possibly be cancer, or if there are other conditions that might match my symptoms, such as chronic bronchitis.
I am currently pregnant; is it safe to have a chest X-ray?

Jie, 20~29 year old female. Ask Date: 2017/09/13

Dr. Zhou Ziguang reply Pulmonology

Chronic cough during pregnancy can be a concerning symptom, especially when accompanied by chest pain and difficulty breathing. It is important to understand the potential causes of these symptoms and their implications for both the mother and the developing fetus.

Firstly, chronic cough can arise from various conditions, including allergies, asthma, gastroesophageal reflux disease (GERD), or chronic bronchitis. In pregnant women, hormonal changes can exacerbate pre-existing conditions or lead to new respiratory issues. For instance, increased progesterone levels can cause relaxation of the smooth muscles in the airways, potentially leading to increased airway resistance and cough. Additionally, the growing uterus can exert pressure on the diaphragm, which may contribute to feelings of breathlessness or discomfort in the chest.

Regarding your specific symptoms of a chronic dry cough, chest pain, and the sensation of tightness, it is crucial to consider the possibility of underlying respiratory conditions. Chronic bronchitis, which is characterized by a persistent cough and mucus production, could be a potential diagnosis, especially if you have a history of smoking or exposure to irritants. However, the presence of chest pain, particularly if it is sharp or associated with breathing difficulties, raises the concern for other conditions, including pneumonia or even pulmonary embolism, which can be serious.

While the concern for cancer is understandable, it is less likely in the context of your symptoms, especially if you are relatively young and have no significant risk factors. However, persistent symptoms warrant further evaluation. In pregnant women, the use of chest X-rays is typically avoided unless absolutely necessary due to the potential risks to the fetus. If imaging is required, healthcare providers will take precautions to minimize exposure.

To address your symptoms, it is advisable to consult with a healthcare professional who can perform a thorough evaluation. This may include a physical examination, lung function tests, and possibly a referral to a pulmonologist. They may also consider non-radiological imaging options, such as ultrasound, to assess any abnormalities without exposing the fetus to radiation.

In the meantime, managing your symptoms is essential. Staying hydrated, using a humidifier, and avoiding known irritants (such as smoke or strong odors) can help alleviate coughing. If you have a history of asthma or allergies, ensure that you are using your inhalers or medications as prescribed. Over-the-counter cough suppressants may also provide temporary relief, but it is crucial to consult your healthcare provider before taking any medication during pregnancy.

In summary, while chronic cough and chest pain during pregnancy can be concerning, they are often manageable with appropriate medical care. It is essential to seek evaluation from a healthcare provider who can guide you through the diagnostic process and ensure both your health and the health of your baby are prioritized.
