Mosquito bites?!
Question:
Mosquito bites?
a bump appears and it itchs like heck? What causes the itch & the bump?
Answers:
Most, but not all people, are allergic to the substance that mosquitos inject in you before sucking your blood. It is an anti-coagulant, that makes it so they can get your blood out before it clots. The cells around where they inject this fluid produce an allergic reaction, which causes the swelling and itching.
