Hey Vini,
I've been checking into the CSF leak issue today. I never had noise bleeds, or a dripping nose (except with a cold) ever, until the fall.
I found a link that may be of interest to you....
www.csfleak.com
It also has links to other sites regarding CSF -
Maybe it will help you through the hurdles of this condition...
Trust your light...follow your path
