It is probably a spider bite.

The reaction that you get on your skin from an insect bite is from the venom within the insect bite. Most insect bites are pretty harmless. This means that although you have been 'injected' with venom your body will build up some antibodies and sort out the problem for you. Some bites though, have a lot of venom in them and will need immediate medical attention. A local skin reaction to a bite from all toxic bugs will look similar:
  • Swelling
  • Redness
  • Itching
  • Pain
If any skin reaction gets worse after 24 hours including redness that spreads away from the actual bite, any fluid seepage, tingling and numbness, more pain or a discoloration surrounding the bite that resembles a bullseye or halo then medical attention must be sought.

  • Spider Bites
Most spider bites are actually quite harmless. Skin sensitivity will be felt but your body will usually get rid of the poison.

There are only a few spiders that will present a human threat. The brown recluse spider and the black widow spider are definitely two arachnids that should be avoided at all costs. Always try to identify the species of any spider that has bitten you and seek medical attention.

  • Mosquito Bites
After a mosquito has bitten you, a red patch of about half an inch diameter will start to surround a small bump. Your skin will be itchy for up to 10 days. This is from an uninfected mosquito. Depending on the country you are in, if you are infected from a mosquito carrying malaria, immediate medical attention must be sought. The venom from a malaria mosquito is usually fatal unless an antibiotic is administered.

  • Bedbug Bites
These bites usually appear as a small, red, raised or flat bump accompanied by itchiness. The bites often appear in a group of three, arranged in a row or cluster. Allergic reactions could include hives, blisters or severe itching.
