In terms of treatment, the primary focus should still be on targeting the common cold, with oral cold medications being the most commonly used. If there is a lot of nasal discharge, you might consider using saline solution to rinse the nasal cavity. Furthermore, if there is significant redness and swelling in the nasal cavity, it is advisable to use a nasal spray medication concurrently, which can effectively alleviate nasal symptoms and also aid in the treatment and recovery from the cold, typically within about a week. During a cold, symptoms of nasal discomfort such as nasal congestion and runny nose can occur. Nasal congestion may be intermittent and alternate between the two nostrils, while the nasal discharge may be purulent or clear. Overall, these are relatively common manifestations.
