- asthma / rhinitis
- A chronic cough (cold)
The common cold often exhibits seasonality, particularly arising during transitional seasons like now when there is a significant difference in day and night temperatures. Just as the saying goes that the common cold can be the beginning of many diseases, not treating it in time can lead to various upper respiratory diseases, with many clinical cases showing rhinitis developing from the common cold.
Due to these reasons, patients with rhinitis often feel a constant heaviness and pain in their foreheads, causing them to furrow their brows. While rhinitis can develop as a post-cold complication if the cold is not properly treated, it can also be caused by various allergies, hence the symptoms can vary widely. If rhinitis is not treated in time, it can complicate into sinusitis, leading to a foul smell from the nose and the discharge of pus-like nasal mucus. When sinusitis develops, frontal headaches become more severe, and nasal congestion symptoms intensify.
