Patients with vocal cord polyps who catch a cold may experience worsening of their condition, which could lead to further hoarseness, as well as possible nasal congestion, runny nose, sore throat, coughing, and phlegm. Therefore, it is necessary to visit an otolaryngologist after the onset of symptoms. Tests such as a complete blood count and laryngoscopy can be performed. Generally, oral medication combined with nebulization treatment can be considered, and regular follow-up examinations are needed to monitor the treatment effects. Most patients will gradually improve with timely medication treatment, but recurring episodes are possible. (Specific medications should be taken under the guidance of a physician.)
