Steaming, steaming, and regular steaming.
Sounds like a severe sinus attack. Steam shower (try to keep your hair out of it though, you don't want to worsen the sinus). Hot towels over the face for a few minutes. Take off immediately once it cools.
And like Tatianna C. says, do the cloth-over-the-head-over-a-pot-of-boiled-water treatment. Do it 3-4 times a day. If you can bear it, rub some Vicks vaporub over your nose and sinus areas before you do this. It'll help to release vapors and help reduce congestion.
And, if your ears are hurting badly, do not try to blow your nose even if you feel the urge to. The pressure it takes to blow your nose, can worsen the ear blockage and can cause ear-aches.
If the aches worsens, consult a pharmacist or a doctor for specialised medicines to help.
Get well soon!
