[|Human|] Hi: Today, from out of the blue, my sinuses went from great, no problem at all, to the right nostril flowing like a faucet. A series of about six sneezes proceeded this. I have no allergies that I know of. The excessive flowing of the right side of my nose has persisted for six hours. What would be my best course of action to stave off a cold or sinus infection. Thanks, bnbm
[|AI|]  HI, thanks for using Chat Doctor Sinus and nasal congestion can be related to different causes, but the most common are infection (usually viral or bacterial) or allergies. If you have no history of allergies, then your symptoms are likely due a viral infection. There are medications that may help you such as oral or topical decongestants. Examples of topical decongestants are striving and normal saline. The oral decongestants are usually sold in combination with anti histamines that are also useful. I hope this helps
