I have nose congestion problem. It doesn't become open whatever I try. How can I improve it?

Hello friends, I have nose congestion problem. Especially when I wake up in the morning, my nose is usually congested but there's not snot in my sinus, just my nose ways are swelled so it prevents my breath regularly. This situation creates headache, dizziness, earache and inhale difficulty. Some of the doctors suggested oceanic water as the spray to me. I use them but there's no benefit occurred. What can I do to breach my congested nose sinuses completely? Please give me natural or medical ways to get rid of nose congestion...

(Memo: I don't want to have an operation as long as I feel any obligation. It will be the last solution.)
