Post-COVID Symptoms: Dry Cough, Nasal Drip, and Throat Irritation

Post-nasal drip, throat dryness and itchiness, dry cough?

Hello, doctor.
Since I was diagnosed on June 28, I have seen significant improvement with medication.
However, I am experiencing a dry cough and post-nasal drip.
I had a laryngoscopy on July 16, and the doctor noted an increased production of phlegm, prescribing expectorants.
Starting July 24, I began to have yellow-green phlegm, and after visiting an ENT specialist, I was diagnosed with acute upper respiratory infection and prescribed antibiotics.
Although I am currently on treatment, I still experience a dry cough, and my throat itches and I cough when I am in dusty environments.
I also feel a bit short of breath after exercising, and in the morning, I have light yellow phlegm from post-nasal drip, but once I cough it out, I remain phlegm-free for the rest of the day.
Additionally, I feel that my sense of smell is not very sharp, and I have a decreased appetite.
Should I see a doctor? Could this be sinusitis? However, I do not have any fever symptoms.

Hello, if the symptoms persist without improvement, it is recommended to visit an otolaryngologist for evaluation to determine whether medication treatment is necessary or if observation is sufficient.

More Info

It sounds like you are experiencing a range of post-COVID symptoms, including a dry cough, nasal drip, throat irritation, and changes in your sense of smell and appetite. These symptoms can be quite distressing, especially after having recovered from COVID-19. Let's break down your concerns and provide some insights based on current medical understanding.

Understanding Post-COVID Symptoms
Post-COVID syndrome, often referred to as "long COVID," can manifest in various ways, and respiratory symptoms are among the most common. The symptoms you describe, such as dry cough, nasal drip, and throat irritation, are frequently reported by individuals recovering from COVID-19. These symptoms can persist for weeks or even months after the initial infection has resolved.

1. Dry Cough and Nasal Drip: A dry cough can be a lingering symptom of respiratory infections, including COVID-19. It may be exacerbated by environmental factors such as dust or allergens. Nasal drip, particularly when you mention it being yellowish, could indicate post-nasal drip, which is often associated with sinus issues or upper respiratory infections.
2. Throat Irritation: This can occur due to several reasons, including the irritation caused by post-nasal drip, which can lead to throat discomfort. The presence of mucus can also contribute to throat irritation, especially if it is thick or discolored.

3. Changes in Smell and Appetite: Altered smell (hyposmia) is a common post-viral symptom, particularly following COVID-19. This can affect your appetite, leading to decreased food intake.
4. Exercise-Induced Symptoms: Feeling short of breath after exercise can be concerning. It may be related to residual lung inflammation or sensitivity following your COVID-19 infection.

When to Seek Medical Attention
Given your ongoing symptoms, it is advisable to consult with a healthcare provider, especially since you have experienced a change in the color of your phlegm and have been diagnosed with an acute upper respiratory infection. Here are some specific points to consider:
- Persistent Symptoms: If your symptoms do not improve with the current treatment or if they worsen, it is important to follow up with your healthcare provider. They may want to reassess your condition and consider additional tests or treatments.

- Potential Sinusitis: While you do not have fever, the presence of yellow-green phlegm and nasal drip could suggest sinusitis, which can occur post-viral infection. A healthcare provider can evaluate this possibility and determine if further treatment, such as nasal corticosteroids or additional antibiotics, is necessary.

- Monitoring Breathing: If you experience increased shortness of breath, especially during physical activity, it is crucial to seek medical advice. This could indicate underlying issues that may need to be addressed.

Self-Care and Management
In the meantime, here are some self-care strategies that may help alleviate your symptoms:
- Stay Hydrated: Drinking plenty of fluids can help thin mucus and keep your throat moist, which may reduce irritation.

- Humidify Your Environment: Using a humidifier can add moisture to the air, which may help ease coughing and throat discomfort.

- Avoid Irritants: Try to avoid exposure to dust, smoke, and other irritants that can exacerbate your symptoms.

- Practice Breathing Exercises: Gentle breathing exercises can help improve lung function and reduce feelings of breathlessness.

- Monitor Your Symptoms: Keep track of your symptoms, noting any changes or patterns, which can be helpful information for your healthcare provider.

In conclusion, while some post-COVID symptoms can resolve on their own, persistent or worsening symptoms warrant further evaluation. It is always best to err on the side of caution and consult with a healthcare professional who can provide personalized advice and treatment options based on your specific situation.
