When You Smell Cigarette or Burnt Odors from Your Nose
It is not common for an unusual smell to come from the nose, but if you do notice unpleasant odors such as cigarette smoke, a burnt smell, the smell of blood, or a metallic smell, you may want to suspect rhinitis or sinusitis.
Of course, because the surrounding air may not be clean, or there may actually be a foreign object inside the nose, it is best to first check the environment around you.

The next step is to check whether you have rhinitis.
Among people with rhinitis, there may not be a particular smell when they have a runny nose, but if it becomes chronic or leads to sinusitis, yellow nasal discharge may appear and an unpleasant odor may also be present.
Because the intensity of the smell each person perceives differs, it may be described in various ways such as sewer-like odor, fishy smell, or cigarette smell, but in the end the cause can be seen as a foul smell resulting from inflammation in the sinuses inside the nose.
In particular, if the infection is caused not by ordinary bacteria but by a fungal organism, the odor may become even worse.
In such cases, ENT clinics recommend antibiotic and antifungal treatment, along with rinsing the nasal passages with saline.

People with rhinitis are more likely than those without it to develop sinusitis, so if you usually experience this kind of discomfort, it is a good idea to manage it at home with measures such as saline rinsing.
These symptoms tend to get worse during dry seasonal transitions or in winter, and at first people may think they are temporary and leave the condition untreated, but if it continues over the long term, you may need to see a doctor.
In particular, sinusitis tends to improve quickly and respond well when antibiotics are taken, but antibiotics are not easy to replace with over-the-counter pharmacy medicine, so a hospital visit is necessary.
Even if no one else knows, it can only be unpleasant if a strange smell is coming from your nose.
Rather than leaving the symptoms untreated, responding quickly would be the better choice.
