From the perspective of Western medicine, there are primarily two types of colds: the common cold and influenza. The symptoms of the common cold are different and mainly include nasal congestion, runny nose, dry and sore throat, tearing, sneezing, and other symptoms. In contrast, influenza mainly manifests as weakness in the limbs, muscle soreness, and some may experience fixed joint swelling and pain. It can also cause complications such as nausea and vomiting, mainly due to infections caused by different pathogens, thus the symptoms vary.
