Serious sinus problems connected to facial fracture

[Samuelson33]

Dear community, I've been trying to find a help for a really long time, I would immensely appreciate any help. My problems started more than 2 years ago, while I was in the US for a year (work related) There I had problems with my nose, i couldn't breathe and it was stuffy all the time. I survived with some kind of special nose spray, which helpes me to just stimulate the pain, I was also taking antibiotics, which helped me to get mucus out but the pain always came back. After coming back to Europe, the pain remained and I did x-ray scan and the doctor said that one side of my sinuses looks like there isn't enough fresh air flowing compared to the other side- may have been caused by facial fracture blocking nassal passage. I was given antihistamine (xyzal) and a nose spray called "Awamys". So to sum up, my sympthomes are : stuffy nose, occasional ear pain, nose pain, head pain (front of the head). If my nose is stuffy also really depends on the weather, and my posture, if I am lying or sitting it is usually really stuffy, but if I am walking, running, doing sport I can breathe easily.
