Sinusitis usually causes coughing. The main symptoms of sinusitis are nasal congestion, purulent nasal discharge, nasal odor, and migraine. Coughing due to sinusitis can be due to postnasal drip syndrome caused by more secretions in the nasal cavity and backing up through the nasopharynx, or it can be due to inflammation spreading directly downward, causing infectious diseases of the airways. Whichever the cause of the cough, it is necessary to treat the nasal infection, the correct use of antibiotics, mucus drainage agents and short-term nasal vasoconstrictors, assisted by saline rinsing of the nasal cavity, which is conducive to the flow of secretions, but also can promote the recovery of mucosal function. The medication should be under the guidance of the doctor, and should not be used without authorization. Normally, you should exercise moderately to improve your immunity.
