Nip to Wal*Mart and buy some 'Equate' (which is their own make)Suphedrine tablets or capsules.
It clears nasal and sinus congestion and sinus pressure.....you can also get it combined with Acetaminophen, which is an analgesic which may be useful.
It costs around $3
There is also a nasal spay available.
If you can't get to Wal*Mart go to a drugstore and have a look on the shelves for items with the active ingredients - no need to buy branded products.
You could also try this for temporary relief -
Force air into the sinuses by raising the pressure in the nose by pinching the nostrils, closing the mouth, and breathing out hard.
I hope you're feeling better soon.
