[|Human|] my son suffered a head injury from a fall from his bike 3 days ago. It is pretty severe but his ct s are good and his bleeding in the brain area has stopped. His facial fractures do not need surgery. 2 days later he is spitting up blood. Is this normal?
[|AI|]  Hello, I hope that I may be able to answer this question.I'm sorry to hear that your son had these injuries. I am happy to hear that his head CT is normal.In regard to the spitting up of blood, this may entirely normal after facial fractures. The tissues of the nose and mouth are very rich in blood supply, and they may bleed very easily. What is more important is how much blood he is spitting up and if it is continues. Persistent bleeding can lead to low blood pressures as well as the possibility of swallowing the blood into the lungs causing respiratory problems. If there is just minimal blood streaking, no dizziness and no breathing problems, I'm not too worried about it. He may spit out blood clots for a few more days. As I said, if her develops constant bleeding or problems catching his breath, you need to go to the hospital.
