The word "urticaria" is pronounced as qián (money), but everyone pronounces it as "seeking", even doctors and nurses. At that time, as a teacher, I often told others that the word was pronounced qián, and nettle was a kind of plant that itched when touched. Who knows that the dictionary has actually changed in recent years, so it is called "seeking" measles in popular parlance, but I still read "qián hemp" on plants. I find it incredible that I changed a monosyllabic word into a disyllabic word, deliberately causing trouble to everyone.
Urticaria is commonly known as rash. It is a localized edema reaction caused by the expansion and permeability increase of small blood vessels in skin and mucosa, which generally subsides within 2 ~ 24 hours, but new rashes appear repeatedly. The course of the disease is delayed for several days to several months. It is more common in clinic.
