Coughing up blood-stained sputum?


Hello doctor, I was recently diagnosed with influenza.
Since yesterday, I have been experiencing a severe sore throat (with persistent coughing) and it hurts a lot when I swallow saliva.
This morning, I coughed up phlegm that had streaks of blood in it.
Should I see a doctor immediately given my condition?

Hello: Coughing up blood is commonly seen in clinical practice and may be related to severe coughing.
However, it is still advisable to at least obtain a chest X-ray to ensure there are no lesions in the lungs for peace of mind.

Coughing up blood, known medically as hemoptysis, can be a concerning symptom that warrants immediate medical attention, especially when accompanied by other symptoms like a severe sore throat and persistent cough. In your case, since you have recently been diagnosed with influenza and are experiencing significant throat pain along with blood-streaked sputum, it is advisable to seek medical care promptly.

When you cough up blood, it is essential to consider the potential causes. While minor causes such as a ruptured blood vessel in the throat due to severe coughing can lead to blood in the sputum, more serious conditions must also be ruled out. These can include bronchitis, pneumonia, tuberculosis, or even lung cancer, especially if the symptoms persist or worsen over time. Given your recent flu diagnosis, it is possible that your respiratory system is under stress, which could lead to complications such as secondary bacterial infections or exacerbation of existing conditions.

In your situation, the presence of blood in your sputum, particularly after a recent illness, should not be taken lightly. It is crucial to have a healthcare professional evaluate your condition. A chest X-ray (CXR) or a CT scan may be necessary to assess your lungs for any underlying issues. These imaging studies can help identify any infections, inflammation, or other abnormalities that may be causing your symptoms.

Additionally, if you are experiencing difficulty breathing or a feeling of tightness in your chest, these are red flags that indicate you should seek emergency medical care. Difficulty breathing can signify a more severe respiratory issue that requires immediate intervention.

In summary, given your symptoms of coughing up blood, a painful sore throat, and a recent flu diagnosis, it is highly recommended that you see a doctor as soon as possible. They can perform a thorough examination, possibly including imaging studies, to determine the cause of your symptoms and provide appropriate treatment. Early intervention can be crucial in preventing complications and ensuring a better recovery. Remember, it is always better to err on the side of caution when it comes to health concerns, especially those involving respiratory symptoms and blood.
