Sever Sinus congest how do I get rid of it?

I started about a week ago with what I thought was sinus issues. That, after 12 hours, went to my chest. Went to Urgent Care and found out I had Bronchitis and possible Upper respitory infection. Put on Z-Pack for 5 days. Finished them Sunday. As of yesturday, I started all over again with the congestion. Its gone from the left side of my nose for yesterday then today to the right and now..both. Ive tried Clain. D, and Tylenol cold. Nothing is working. Ive been on clar D for a week or so, and Tylenol for 2 days. I feel find other wise. Im coughing but that is from the Bronchitis. Im not really hurting from the pressure just congestion. Does anyone have ANY ideas other than the humidity. I did do some major cleaning and stirred up a ton of dush. Thats when It started.
