Forceful Breaths Through Nose Whats Wrong I Can't Sleep Good

Could I find out what could cause you to forcefully suck in air through your nose? This happens to me while awake, when I am just falling asleep and very frequently while asleep. I have 15 to 20 arousals an hour in my sleep from this and suffering extreme fatigue because of it. During deep sleep I quit moving with these breaths but never during the other stages of sleep. I get up alot in my sleep having to rub my nose and it's obviously irritating me even when i'm not awake! I video taped this so I am very aware of what's going on. I also had a sleep study but unfortunetly didn't reach most of the stages of sleep, but had 18.5 arousals an hour regardless. I have pain and pressure in the upper area of my nose, blood sometimes mixed in the mucus, dryness and burning, frequent otitis media, headaches and sore throats. Any idea what may be doing this to me? I recently went to an ent doctor but he totally ignored these problems as I looked fine in his office so he sent me home with some nose spray, said my sinus problems was probley tmj and didn't give me a follow up visit. So please help.. Thanks!
