Blood-Streaked Mucus: When to Seek ENT Evaluation - Otolaryngology

Nasal mucus with blood streaks?


Hello, doctor.
My symptoms include a runny nose, post-nasal drip, and occasionally blood-tinged mucus or phlegm, which usually occurs in the morning and happens about once a month.
The blood is very minimal and varies in color from dark to deep.
Does this look like nasopharyngeal cancer? Should I get it checked, or should I just observe? I also experience tinnitus, a buzzing sound in both ears, which is more noticeable when it's quiet, but this occurs only once or twice a month and resolves quickly.
I have a history of nasal allergies and have had post-nasal drip for one to two years.
I have not had blood-tinged mucus in the past year, and there is no family history of nasopharyngeal cancer.

Hello, Xiao Bai: If you have persistent nasal discharge with blood streaks, it is advisable to seek medical evaluation to determine whether the bleeding source is in the nasal cavity or the nasopharynx.
Local treatment or medication may be used to improve the condition.
Wishing you safety and health.
Sincerely, Dr.
Cheng Jue-Yi, Director of the Department of Otolaryngology, Taoyuan General Hospital, Ministry of Health and Welfare.

When it comes to symptoms such as blood-streaked mucus, nasal congestion, post-nasal drip, and occasional ear ringing, it is essential to approach the situation with a balanced perspective. While these symptoms can be concerning, especially when blood is involved, they are not definitive indicators of serious conditions like nasopharyngeal cancer.
Firstly, let’s break down your symptoms. Blood-streaked mucus can arise from various benign causes, particularly in individuals with a history of nasal allergies or chronic sinus issues. Allergic rhinitis, which you mentioned you have, can lead to inflammation and irritation of the nasal passages. This irritation can cause small blood vessels to rupture, resulting in blood-streaked mucus. The fact that you experience this symptom infrequently (about once a month) and in very small amounts is reassuring.
Post-nasal drip, which you have been experiencing for one to two years, is another common condition associated with allergies or sinusitis. It occurs when excess mucus accumulates in the back of the throat, leading to coughing or throat clearing. This can also contribute to the sensation of ear ringing or tinnitus, which you described. Tinnitus can be caused by various factors, including ear infections, sinus pressure, or even stress, and it is often temporary.

Given that you have no family history of nasopharyngeal cancer and that your symptoms are intermittent and mild, it is likely that your symptoms are related to your known allergies rather than a malignancy. However, it is crucial to monitor your symptoms closely. If the blood-streaked mucus becomes more frequent, increases in volume, or is accompanied by other concerning symptoms such as significant weight loss, persistent pain, or changes in your voice, it would be prudent to seek an evaluation from an Ear, Nose, and Throat (ENT) specialist.

An ENT evaluation is particularly recommended if you experience any of the following:
1. Persistent Symptoms: If the blood-streaked mucus occurs more frequently or if you develop new symptoms.

2. Duration: If symptoms last longer than a few weeks without improvement.

3. Associated Symptoms: If you experience significant pain, swelling, or other systemic symptoms such as fever or night sweats.

4. Changes in Hearing: If the ear ringing becomes more pronounced or is accompanied by hearing loss.

During an ENT consultation, the specialist may perform a thorough examination, which could include a nasal endoscopy to visualize the nasal passages and throat. This examination can help identify any underlying issues such as chronic sinusitis, nasal polyps, or other abnormalities that may require treatment.

In summary, while your symptoms are likely benign and related to your allergies, it is essential to remain vigilant. If you notice any changes in your symptoms or if they worsen, do not hesitate to seek medical advice. Regular follow-ups with your healthcare provider can help manage your allergies and any related symptoms effectively. In the meantime, consider discussing your symptoms with your primary care physician, who can provide guidance on managing your allergies and when to refer you to an ENT specialist.
