Morning phlegm can be a perplexing symptom, especially when it occurs consistently upon waking and resolves throughout the day. Your description of yellow phlegm in the morning, with no accompanying nasal congestion or post-nasal drip, suggests a few potential causes that we can explore.

Firstly, the presence of yellow phlegm often indicates that your body is responding to some form of irritation or infection. While you have been evaluated by two ENT specialists, and the first suggested sinusitis, it’s important to consider other factors that might contribute to your symptoms. Chronic bronchitis, allergies, or even environmental irritants could be at play here.

1. Chronic Bronchitis: This condition is characterized by inflammation of the bronchial tubes, leading to increased mucus production. If you are a smoker or have been exposed to secondhand smoke, this could be a contributing factor. Additionally, chronic bronchitis can be exacerbated by environmental pollutants or allergens.

2. Allergies: Allergic reactions can lead to increased mucus production, particularly in the morning when allergens such as dust mites or pet dander may be more concentrated in your sleeping environment. If you have a history of allergies, this could be a plausible explanation for your symptoms.

3. Environmental Irritants: Consider your sleeping environment. Factors such as dry air, air conditioning, or exposure to pollutants can irritate your airways, leading to increased mucus production. Using a humidifier in your bedroom might help alleviate dryness and reduce phlegm production.

4. Gastroesophageal Reflux Disease (GERD): Although you mentioned no symptoms of post-nasal drip, GERD can sometimes present with phlegm in the throat upon waking. If you experience any heartburn or acid reflux, this could be worth investigating further.

5. Infections: While your symptoms may not align perfectly with sinusitis, other respiratory infections could cause morning phlegm. If you notice any changes in your symptoms, such as fever or increased phlegm production, it would be advisable to seek further medical evaluation.

Given that your symptoms have persisted for nearly a year, it would be prudent to follow up with a healthcare provider who can conduct a thorough evaluation. This may include imaging studies, such as a CT scan of the sinuses, or pulmonary function tests to assess for any underlying respiratory conditions.

In the meantime, here are some strategies that may help manage your symptoms:
- Stay Hydrated: Drinking plenty of fluids can help thin mucus, making it easier to expel.

- Use a Humidifier: Adding moisture to the air can help soothe irritated airways and reduce mucus production.

- Avoid Irritants: Try to minimize exposure to smoke, strong odors, and other environmental irritants.

- Monitor Allergens: If you suspect allergies, consider using hypoallergenic bedding and regularly cleaning your sleeping area to reduce dust and allergens.

In conclusion, while your morning phlegm may not be indicative of a serious condition, it is essential to identify the underlying cause to effectively manage your symptoms. A comprehensive evaluation by a healthcare professional can provide clarity and guide appropriate treatment options.
