What Causes Congested Nose With Difficulty In Breathing?

Hello... Last night when I was asleep I felt that I was having some node congestion, I m getting over the flu /cold, I m not really sure which one I had but the thing is that I was getting over it already but I just had like a really stuffed up nose yesterday so even I would blow my nose up I wasn t able to, well get anything out but I just felt my nose really stuffed up. Due to that I I went to sleep mouth breething, so last night in the middle of my sleep I guess I wasn t able to breath well so, me half asleep I blew my nose and was able to clean something out the thing that I don t remember how hard I did it because I went to sleep right away like I said I guess I was half asleep. So like at 5:45am I woke up because something was bothering me I felt something was bothering me so I woke up and Minutes later I felt like a small pain on my right ear, so I thought it was like a pain that sometimes I have from sleeping on just one side pushing all the weight from my head to my ear so I touched it and rubbed it to make the pain away like I always do, (pain like a sleep body part from to much pressure) I guess =) anyways I tried to do that but I could felt that I wasn t that kind of pain but inside so the minutes were passing by and I was feeling like a stingy kind of pain when like you re cleaning your ear with a Q-tip and than you go deep enough to hurt yourself kind of pain. So I looked that up already and none of the most common symptoms I read about an infection I have but the stuffy nose. I don t have fever nor I have strep throat. Why does my ear hurt, could it have been due to blowing my nose without me being 100% sure how hard I blew my nose? Is this dangerous? Do I need to see a Doc about it?
