What is causing fluid to flow from my nostril?

Question:
Once on the first of Oct and again on the 25th of December 2014, I was sleeping and I woke up both times with this fluid gushing out of my left nostril.  In June 2014 I fell and had quite a serious fall on my left side.

I had a huge lump on my head and had a J/C shoulder separation.
I would like to know what causes this fluid problem?

It is possible that the fluid coming from your nostril could be cerebral spinal fluid. This could result from a fracture of the skull base which is the thin bone between the roof of the nose and sinuses and brain.

You should see an otolaryngologist who will most likely ask you to collect the fluid so it can be analyzed in a lab, get CT scan and/or MRI scan and perform a nasal endoscopy.
Good luck.

I hope this clears things up.
