I agree with both answers!!!!! I actually have a funny story about mosquitos!!!! One day, we were observing a mosquito picture in science. so, our teacher told us one time, a mosquito landed on her arm and started sucking blood from her. She tightened her arm, and the mosquito got all big and fat!!!!! It started to fly away, but it was hard!!!! well, our teacher didn't want it to stick around, so she flicked it and it blew up!!!!!! FUNNY!!!!!
When you get that little bump its called swelling and that is full of "poison" and our bbrain to get us away from the pain tell us its an itch so when we itch we are pushing the poison further into our skin causing rash that my friend is why it itches Q
