Why is there a lump under my bug bite?

Answer by  EddyNfld (147)

The lump you find under a bug bite is your body trying to fight the substance that was secreted into your body. When a mosquito bites it releases a anti-coagulant that your body uses anti-histamines to fight off the effect thus causing swelling. Other bug bites are similar to this.

More often than not the lump you are referring to is swelling caused by the injection of venom from the bug at the bite location. This swelling may harden a bit after the initial bite. It will eventually go away after a few days. Try not to itch the bite as that can cause an infection.
