At around 4pm yesterday I went to bed early because I was really tired. I woke up around 5 and felt a small bug go up my nose. It seemed very small. I felt it go in and all the way back, I do not remember anything crawling on my face so I think it was a flying tiny bug. I tried blowing it out but it stayed put. I fell back asleep thinking it would probably just die in there and come out later. However its now 5am the next day and I can still feel it moving around which feels horrible. Its starting to smell bad too. It seems to be on the other side of my nose now rather than the way it came in. Its grossing me out at this point. Whenever it moves it kind of hurts and the smell is getting worse. It seemed so tiny though so I did not think it would really matter. Help :( 

I am starting to question what it is. I thought it was a small gnat or something but now I am worried its a spider or something bad.
