Sinus issues

Since I’ve found out I was pregnant with my middle child (August 2017) I’ve had nothing but sinus issues. My nose can go from “breathing easy” to completely stopped the eff up. My doctors have prescribed me nasal spray, countless decongestants, and given me suggestions on how to loosen it to get it out. But nothing works. I’m so fed up with it and I’m miserable. I can’t even eat without struggling to breathe. My doctor says the same thing every time I mention it or they’ll call in a new med that just doesn’t work. Or if by some miracle it does it only lasts 30 minutes TOPS. Has anyone had similar issues? What in God’s name did you do to help or finally end the congestion nightmare.
