What Causes A Nasal Drip Now?

Hi , about two month ago i injuryed my lower back, i get tingles in the left soulder blade and part of neck, this comes and goes, the dr said i may have stranded a mussel, im not sure if its related but my nose drips from the right side only when leaning forward, i dont get headaces, but did suffer from constint ear infections as a child through to my teenage years, i had gromits put in when i was 12- my left one didnt full out on its own the dr used somethong like a hook to remove it which was cery painfull , at the time the dr 1st didnt beleive me that it was still in there after two years and when he removed it the pain he said i was just being silly. I have loss part of my hearing in that ear and other doctors snice have said my eardrum is damaged , could this all be related or should i be worried inregards to my nose drips??
