Sudden cough lasting for one month?

I have a history of nasal allergies.
Last month, one night I suddenly felt an itch in my throat, and since then I've been coughing intermittently.
I have never experienced these symptoms before.
The cough is accompanied by a severe wheezing sound, and while I can't seem to produce much phlegm, there might be a little or possibly post-nasal drip.
My usual allergy-related nasal discharge is clear.
Due to my long-term nasal allergies, I can't determine if the sneezing and runny nose are related, but aside from the sudden persistent cough, I haven't experienced any other cold symptoms, not even nasal congestion.
Sometimes I cough continuously, but I can manage to suppress it.
My chin feels slightly swollen, but it doesn't hurt.
Currently, I am taking medication for mental health, including sedatives and antidepressants, as well as medication for heart rhythm issues.
In the past, even when I had a cold, I didn't experience lingering effects, but this time I haven't even had a cold and have just been coughing for a month.
I'm unsure whether I should see a doctor for a cold.
Honestly, I really don't want to see a doctor unless absolutely necessary; visiting the mental health clinic once a month is already exhausting.
However, I can't continue coughing indefinitely.

More Info

Persistent coughs can be quite distressing, especially when they linger for an extended period, as you have described. Given your history of nasal allergies and the recent onset of a cough accompanied by wheezing, it is essential to consider a few potential underlying causes and management strategies.

Firstly, your symptoms suggest that you may be experiencing an exacerbation of asthma or an allergic reaction. Asthma is characterized by inflammation and narrowing of the airways, which can lead to symptoms such as wheezing, coughing, and difficulty breathing. In your case, the sudden onset of a scratchy throat followed by a persistent cough could indicate that your airways are reacting to an allergen or irritant. This is particularly relevant since you have a history of nasal allergies, which can often coexist with asthma.

The presence of a cough that is worse at night or when lying down may also suggest post-nasal drip, where mucus from the nasal passages drips down the back of the throat, triggering a cough reflex. This can be exacerbated by allergies, leading to increased mucus production. The fact that you are experiencing wheezing further supports the possibility of asthma, as wheezing is a common symptom associated with bronchial constriction.

In terms of management, it is crucial to identify and minimize exposure to potential allergens. Common triggers include dust mites, pet dander, pollen, and mold. Implementing measures such as using air purifiers, regularly cleaning your living space, and avoiding known allergens can help reduce your symptoms. Additionally, maintaining good hydration can thin mucus secretions, making it easier to clear from your airways.

Since you have been experiencing this cough for a month, it is advisable to consult with a healthcare provider, preferably an allergist or pulmonologist. They can perform a thorough evaluation, which may include lung function tests, allergy testing, and possibly imaging studies to rule out other conditions. If asthma is confirmed, a tailored treatment plan may include the use of inhaled corticosteroids or bronchodilators to manage inflammation and open the airways.

Moreover, if you suspect that your cough may be related to gastroesophageal reflux disease (GERD), which can also cause throat irritation and cough, discussing this with your doctor is essential. Lifestyle modifications, such as avoiding large meals before bedtime and elevating the head while sleeping, can help alleviate symptoms.

In summary, while your persistent cough may be linked to your history of allergies and potential asthma, it is important to seek medical advice to confirm the diagnosis and establish an effective treatment plan. Managing allergies and asthma proactively can significantly improve your quality of life and reduce the frequency and severity of your symptoms.
