###Human: Is it normal to get dryness in the nostril? ###Assistant: Hi. Do not worry at all. It does not look like cancer at all. All the symptoms you have seem to be for chronic sinusitis. The antibiotic you had is not bad but according to my opinion it is not enough to treat sinus infections in adults, so I recommend Medofloxine 750 mg once daily for 10 days. Medofloxine is a Fluoroquinolone. In case you cannot find it in your country you can use Moxifloxacin 400 mg for ten days which is a Fluoroquinolone too. Also, you need to add a mucolytic to liquify the mucus inside your sinus. Continue the Flonase. After 10 days of treatment if no improvement, you have to perform a CT scan for your nose and sinuses to see what is the shape of the pathology inside your sinus. As the infection can be fungal, not bacterial but fungal infection is rare although it is a far possibility.
