Why do mosquito bites form bumps?
September 30, 2008 2:46AM
This is what I pulled from another site. "After the bite, some saliva of the mosquito remains on the wound. The proteins present in the saliva evoke an immune response in the body. The area that is bitten swells up and is called the wheal. After some time, the swelling goes away but the bitten area will continue to itch until the immune cells of the body break down the saliva proteins.
