Sinus Medication Solution

My sinus’ are terrible, I am congested, I have this stuffy, sticky heavy feeling in my nose all of the time, when I mash on each side of my nose, I can actually feel the stuff moving around there. I constantly snort and feel like I am choking on thick mucus, when I blow, nothing comes out..I thought that smoking may have been the problem but, I have quit 4 weeks ago and still had no relief. I have constantly went to the doctor, been on many antibiotics and even had sinus surgery last year and still no relief. I have had a complete blood work up testing for Mold and things, the only thing I am allergic to is dogs. I have not had the skin test yet. I am miserable! Please help!!!!!
