Q:

What does it mean to have a bruise around a bug bite?

A:

Quick Answer

Developing a bruise after getting bit by a bug is from skin bleeding caused by a chemical the bug used while feeding, a stinger or a certain insect venom. When the skin bruises, it simply means that there has been a loss of oxygen to the skin cells, which is usually a result of a ruptured blood vessel beneath the surface.

Full Answer

Some insects, such as the common louse, chigoe fleas and bed bugs, are actually human parasites, which means that they feed on human blood. These pests latch onto or burrow into the skin as they breed and lay eggs. As these creepy crawlers derive nutrients at the host's expense, they sometimes leave bruises behind that swell on top of the skin.

As the wound begins to heal, the bruise often changes colors; this is part of the healing process and is totally normal. If the area around the bite is causing intense pain or abdominal cramps, see a doctor immediately in order to rule out complications from the bite. If the bruise around the bite increases in size and remains firm, it is possible that a hematoma has formed. A trip to the doctor may be required to drain it.

    What is a tic bite?

    A:

    A tick bite is the area where a small, blood-sucking arachnid known as a tick latches onto the skin and begins drawing blood. Ticks normally stay latched onto the host for extended periods, so individuals who find tick bites are likely to find the tick still attached, according to Healthline.
