how do you unstuff your nose fast?

maybe you have swollen sinuses and there nothing there TO blow out.

A decongestant ir in the mean time a hot shower might help.

Nasal sprays or...this may be a little painful, but pour water in your nose and that might loosen the snot built up in your nasal passage.

You're congested. Taking a decongestant (Sudafed) or an antihistamine (allergy medication) will help.

drugs are bad. I sniff weak warm salt water up my nose.

Allergex...its very effective and very cheap..its what i use..(contains Chlorpheniramine maleate 4mg) as its active ingredient
