Suddenly?: Sudden nasal congestion can be from a viral infection. If you have been developing choking in your sleep for a while with some nasal congestion and now your nose is completely blocked you may have nasal allergies and post nasal drip. Depending on the duration of your symptoms either see your primary or an allergist.
