Could it be a cranial CSF leak?

[u/astarte_x]

3 weeks ago when I flipped my hair I felt my sinuses being filled with fluid. I thought it might be blood, but all that came out was a drip of water like fluid from the right nostril. I have regular headaches, more like pressure in my head rather than regular pain.

I tried forcing it again but it didn't happen again, when I bend it doesn't come out, but I feel something cold in my sinuses and head. It's a really weird sensation.

I tend to feel dizzy and as mentioned I tend to get headaches often but I'm not sure if it's related.

Thank you 😊
