Nasal mucus with blood clots?


Hello, doctor.
I recently caught a cold, but aside from a sore throat and fever, my nasal discharge isn't severe, and I don't feel particularly congested—basically, I don't need to blow my nose much.
I do have some phlegm in my throat.
This morning, I had a bit of a runny nose, and after blowing it for a while, I suddenly felt like mucus from deep within my nasal cavity was expelled, and the amount increased significantly.
I also blew out a small piece that looked like a blood clot or a blood blister.
However, after blowing my nose, I didn't have any nosebleeds; I just felt incredibly clear in my nasal passages.
What could this be a symptom of? Or is it just an accumulation of mucus?

More Info


Understanding blood-tinged mucus can be concerning, especially when it appears unexpectedly during a cold or respiratory illness. In your case, experiencing a sudden increase in nasal discharge, accompanied by a small blood-tinged clot or bubble, can be attributed to several factors related to your current health condition.

Firstly, during a cold or upper respiratory infection, the mucous membranes in your nasal passages can become inflamed and irritated. This inflammation can lead to increased mucus production, which is your body's way of trying to clear out pathogens and irritants. When you blow your nose forcefully, it can cause small blood vessels in the nasal lining to rupture, leading to blood-tinged mucus. This is often harmless and resolves as the inflammation decreases.

The presence of blood in your mucus can also indicate dryness in the nasal passages, especially if you are in a dry environment or if you have been using decongestants that can dry out the mucous membranes. Additionally, if you have been coughing or clearing your throat frequently due to throat irritation, this can also contribute to minor bleeding.

It’s important to note that while occasional blood-tinged mucus can be benign, there are situations where it may warrant further investigation. If you experience persistent bleeding, significant amounts of blood, or other concerning symptoms such as severe headaches, facial pain, or changes in vision, it would be advisable to seek medical attention. These symptoms could indicate a more serious condition, such as a sinus infection or, in rare cases, a bleeding disorder.

In your case, since you mentioned that you are experiencing a sore throat and fever, it’s likely that the blood-tinged mucus is related to your upper respiratory infection. Here are some recommendations to help manage your symptoms:
1. Stay Hydrated: Drinking plenty of fluids can help thin the mucus and keep your nasal passages moist, reducing the likelihood of bleeding.

2. Use a Humidifier: Adding moisture to the air can help soothe irritated nasal passages and prevent dryness.

3. Avoid Irritants: Stay away from smoke, strong odors, and other irritants that can exacerbate nasal inflammation.

4. Gentle Nose Blowing: When you need to blow your nose, do so gently to avoid causing further irritation or bleeding.

5. Monitor Symptoms: Keep an eye on your symptoms. If they worsen or if you develop new symptoms, consider consulting a healthcare professional.

In conclusion, while the presence of blood-tinged mucus can be alarming, it is often a benign symptom associated with nasal irritation and inflammation during a cold. However, if you have any concerns or if your symptoms persist, it’s always best to consult with a healthcare provider for a thorough evaluation and personalized advice.
