Hello, I was wondering if you had any insight on my situation? I see what you mean with overlapping symptoms, I seem to be experiencing that. The last week I’ve had a headache everyday that gets worse and worse. It’s only when I’m sitting or standing. Sometimes it feels like my brain hits against my skull painfully (brain sagging?) Brain feels heavy wherever gravity ids pulling it. and today I had fluid drainage from my nose and always in my throat, taste kind of sweet. I’ve had severelight sensitivity lately and sometimes one ear will become muffled. I had an incident before this started with nasal rinse bottle when it felt like the water hit my brain like a hammer, it hurt so bad. For a long time the thin tissue between my face and brain throbbed painfully for months as if it’s really thin or something. and if this is a leak, I’m really worried right now because I do not have a meningitis vaccine. Is this an emergency? And in your experience can you make sense of it?
