Understanding blood-streaked nasal discharge can be concerning, especially when it persists over time. Based on your description, it seems you have been experiencing a combination of nasal congestion, colored nasal discharge, and occasional blood-streaked mucus. Let's address your questions and concerns systematically.

1. Possible Causes of Blood-Streaked Nasal Discharge:
The presence of blood in nasal discharge can arise from several factors. The most common cause is trauma to the nasal mucosa, often due to vigorous nose blowing or irritation from allergies. In your case, the doctor suggested that the blood could be due to ruptured capillaries from excessive force when blowing your nose. However, other potential causes could include chronic sinusitis, nasal polyps, or even more serious conditions like infections (bacterial or fungal) or tumors, although these are less likely given your recent evaluations. The dark red or black color of the discharge could indicate old blood, which may have been present for some time. While fungal infections can cause nasal symptoms, they typically present with additional signs such as persistent pain, swelling, or systemic symptoms like fever.

2. Duration of Microvascular Bleeding:
If the bleeding is indeed due to microvascular rupture, it is generally expected to heal within a week or two, depending on the severity of the trauma and individual healing factors. However, if you continue to experience blood-streaked mucus for an extended period, it may suggest that the initial injury has not healed properly, or there may be ongoing irritation or inflammation in the nasal passages. Factors such as dry air, allergies, or even underlying conditions like hypertension can contribute to prolonged bleeding.

3. Next Steps for Persistent Symptoms:
Given that your symptoms have persisted despite treatment and evaluation, it would be prudent to continue monitoring your condition. If the blood-streaked mucus continues to appear, or if you develop new symptoms such as increased pain, fever, or changes in your sense of smell, it would be wise to return to an ENT specialist for further evaluation. They may consider additional diagnostic tests, such as a CT scan of the sinuses, to rule out any underlying issues that may not have been visible during the initial endoscopic examination.
In summary, while the initial assessment points towards trauma-induced bleeding, the persistence of your symptoms warrants further investigation. It is essential to maintain open communication with your healthcare provider and report any changes in your symptoms. If you feel uncertain or anxious about your condition, seeking a second opinion or further evaluation can provide peace of mind and ensure appropriate management.
Lastly, managing your allergies effectively with the prescribed nasal spray and avoiding irritants can help reduce nasal inflammation and potentially prevent further bleeding. Stay hydrated and consider using a humidifier to maintain moisture in the air, which can also aid in healing your nasal passages.
