Dan zhen (Erythematous rash) refers to generalized swelling, with white dan-like rashes emerging within the muscles, accompanied by slight itching, pain, and swelling. It resembles the red patches appearing during an attack of wind wheals (Yin zhen). There are also cases where the rash rises like a rooster's comb, bright red in color, with a size comparable to a coin. Some may present with blisters.
