The length of recovery time for nasal incompetence with the cold is related to the patient’s condition and treatment effect, as follows: 1. mild common viral cold: when accompanied by nasal incompetence, by paying attention to rest and drinking more warm water, some patients can mostly relieve themselves in 2-3 days. 2. heavy cold: the recovery time for nasal incompetence is extended, requiring oral cold medication and antihistamines such as loratadine. 3.Bacterial sinusitis secondary to common cold: the recovery time of the symptoms of nasal disinflation is also significantly longer, and such patients need to be treated with anti-infection and local treatment of the nose, and the recovery time of patients may take 1-2 weeks. Therefore, because of the different conditions of the cold, the recovery time of symptoms such as nasal disinflation is also different.
