A member asked:
A mosquito bite resulted in an allergic reaction of 4" red bump with 3" darkred center that's turning purple. is that normal for an allergic reaction?
A doctor has provided 1 answer
That sounds like: a localized allergic reaction. No, most- people don't have that significant of a reaction. The mosquito's saliva contains a substance that effects clotting - which is why the lesion is purple.
