Hi and welcome to HCM! Thanks for posting your query here. The severity of your injury is not mentioned. Anyhow, the symptoms you are saying about is of CSF rhinorrhea- leaking of CSF-cerebro spinal fluid from the nose. It is seen in the basilar skull fractures which is the fracture at the base of the skull. It may leak from the ears also where it is called as CSF otorrhea. Headache and visual disturbances are commonly associated with it. Because of the leakage there are chances of entry of bacteria to the meninges which results in meningitis. A skull x-ray will give the diagnosis. An MRI or CT will give the extent of injury to the soft tissues. A blood and csf culture will give the microscopic picture of the analysis. As it is a dangerous condition I advise you to meet your doc as soon as possible. Hope this is helpful to you. Regards
