I went into the doctor a week ago to see if they would prescribe me anything for my post nasal drip, since it was draining all the time. I have suffered from a runny nose my entire life, but I have just always dealt with it. The day I went to the doctor my nasal passages were clear, but had runny fluid. I started Flonase that night and immediately after taking the first dose I could not breathe through my nose. For a week straight my nasal congestion has not gone away and I have still yet to show any signs of improvements. I mean yes the drainage stopped going down my throat, but that is because it is stuck in my nasal passages. Is this normal with Flonase? When should I feel relief?
