You could try a netipot. Great for sinus congestion. It's like a little watering can which you use to pour saline up your nose and it comes out the other side with all the gunk. I once used sprays to stop my nose and ears blocking (they'd worked fine on other occasions) and I ended up with a sinus infection. I think maybe it was due to the fact that the gunk never had chance to get out. I felt like I had severe toothache due to the pressure in my nose and ears.
A friend recommended a netipot, so I got one. At first the water went up but nothg happened. Then I felt a bubbling going on up there and there was a gush of water and what looked like a big blob of lime jelly (sorry, bit graphic). Relief was instant. So now, if there's any kind of congestion going on, I always start with my netipot. It's good for hay fever because it flushes the pollens that cause the irritation away.
