As the leak from the right nostril would not stop, the boy, who had not been named, went to the doctor. After performing a image exam, he found that the liquid being expelled from the right nostril wasn't just some nasty nasal fluid.

dangerous but not too
Leaks of this fluid are not unheard of, however, they are quite rare, in most cases, the loss of CSF is directly linked to a pre-existing defect in the skull. Despite being a very uncomfortable situation, the case is quite rare.
Loss of CSF is not necessarily harmful, and people with this condition can live for years without any problems. However, the loss of this fluid makes patients more susceptible to brain infections, such as meningitis, because the central nervous system gets more exposed.
