I have a rare condition called a CSF leak. It's rare because mine is a spontaneous leak and not from trauma. It's called SIH (Spontaneous Intracranial Hypotension). Typically, when someone has this condition, they go misdiagnosed for several months. I was misdiagnosed for 2 months and 3 different doctors with having a sinus infection. I was lucky to get Dr Litchmore in the ER, who could tell there was more going on and I was diagnosed properly!!
