[|Human|] My 6 yr old son ran into a boy who stopped suddenly. Brow and zygomatic were a bit swollen and bruised. Son said later he threw up. face red hue for 2 days. couple days later he has a runny nose. Is this related or just by chance? Perhaps slight concussion?
[|AI|]  Hi, thank you for posting! I have gone through your query and I understand your concerns. According to the medical history of the child, I think that your son suffers from the cerebral commotion and vomiting is a signification sign of this. Also, the runny nose is related to the history and shows an injury of the nose bones. I think that your son needs to be treated in the ER(emergency room), and he should get some tests done: head X-Ray, MRI(magnetic resonance imagery), complete blood count, urine test. The diagnosis and the treatment should be done by a neurologist and otolaryngologies. All the best,
