Why do I get a recurring bad smell from my nose?

Hello,

Welcome to icliniq.com.

I understand your concern.

A bad smell coming from the nose that comes and goes is often caused by something inside the nasal passages or sinuses rather than a serious systemic disease. When this odor returns after months, the most common reasons include chronic sinus infection, dried mucus trapped deep in the nasal cavity, and a small area of bacterial overgrowth. It could also be due to a foreign body or if something was stuck in the nose earlier without your notice. Another possibility is a condition called atrophic rhinitis, where the lining inside the nose becomes dry and forms crusts that produce a strong smell.

Sometimes, a decayed tooth or gum infection can also create a smell that feels like it is coming from the nose. Since you have no fever, no discharge that you can see, and are not currently under any medications, it is hard to know the exact cause without a proper nasal exam. Many people with chronic sinus inflammation also report a foul smell, even when there is little visible mucus.

Also, let me know if you have nasal blockage, one-sided discharge, thick mucus, facial pressure, or post-nasal drip. Does the smell get stronger when you lie down, bend forward, or press on your cheeks? Or has anyone ever told you that you snore or breathe through your mouth because of congestion?

Your answers will help me understand whether this is related to a sinus infection, dryness, or something else, so that I can guide you on the appropriate management.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
