Nasal sprays like Afrin and Neo-Synephrine, and the others are decongestants. Decongestants are for stuffy nose but do not relieve allergies. You could also use saline nasal sprays, but these are still not anti-allergy.
Cyclobenzaprene, the generic form of Flexeril, which is a skeletal muscle relaxant, can increase the effects of certain nasal decongestants. I don't know which ones are in Nyquil, (you can read the label to see which ones are in it), but the nasal decongestants that it can increase the effects of are: naphazoline, oxymetazoline, phenylephrine, and xylometazoline.

The easiest and most accessible way to treat nasal congestion is simply to blow one's nose. However, if that does not relieve the symptoms, or if the congestion is longer lasting one could try over the counter or prescription nasal sprays or decongestants. Many natural remedies such as inhaling steam or eucalyptus oil have also been know to help.
To open up sinuses, you can try using a humidifier, taking a hot shower to breathe in steam, using a saline nasal spray to moisturize the nasal passages, or drinking plenty of fluids to thin mucus. Over-the-counter decongestants or antihistamines may also help.
