What Could Cause Sudden Spitting Up Of Phlegm With Blood After Traveling To A Canada?
I've never had such an unusual incident without any obvious contributing factor.
Investigation is required
Detailed Answer:
Hello,
The presence of blood in the phlegm is always alarming unless we have a very good explanation for it. In your case, we don't seem to have one, therefore investigation is recommended. The metallic taste was obviously from the blood.
The upper respiratory tract (nose, mouth, larynx) and the lower respiratory tract have to be checked. The upper part can be checked clinically (an ENT specialist can do that). The lower part is better assessed radiologically (starting with a chest X-ray) although in some cases more invasive measures (bronchoscopy) may be necessary.
In conclusion, the site of bleeding has to be found. Problems with the teeth and gums are simple benign causes of such bleeding. Other causes may include more serious disorders including cancer.
I hope you find my comments helpful!
