How can I get rid of a blocked nose?!

turn the shower on really hot and just sit by it and breath in the steam that's what I do for my little brother when he gets a stuffy nose, oh and don't forget ot close the bathroom door so the steam doesn't get out

Easy but lame method
boil a glass of water..........OK you will eventually see steam coming out so what you would do now is inhale that steam and due to its heat your nose will cleaned from inside. hoped it helped and yes its weird but dont do it if you have medicine with you =D.

You can heat the water and breathe in the vapor about several minutes and several times a day.

Go to the pharmacy and get some saline nasal spray. It's cheap, effective and gentle. If the problem persists, see your doctor. You may have a sinus infection.
