Spiders and symptoms of a spider bite

The most dangerous spiders are those who can transfer enough venom to harm the bitten person with one single bite. Non poisonous spider bites are followed with symptoms which last for five to sixty minutes. Poisonous spider bites, on the other hand, are often painful for longer than twenty four hours.
The poisonous spider bite and the effect of its poison is the primary thing to be concerned about. When a spider injects venom into the skin it causes spider envenomation.
A spider bite can not be detected sometimes since a spider does not commonly bite twice. All spiders are poisonous but most of them can not inject poison into human skin and they do not have the sufficient amount of venom to harm a person.


- Sharp and momentary pain similar to the sting of an insect
- Redness
- Itch (in some cases)
- Swelling up.

Spider bites are mostly just uncomfortable and their symptoms do not last very long.
The most important thing to be aware of is the question if you were bitten by a poisonous spider, or a non-poisonous spider who may be the carrier of some disease.

Some United States spiders have specific bite symptoms which can be easily recognized. These include the black widow, the brown recluse spider etc. These spider bite symptoms usually last for only a couple of hours or a few days. More serious reactions which occur due to hypersensitivity to spider bites are mostly very rare.
Extremely sensitive people, those who are allergic to bites of certain spiders, could have serious health complications.
The reaction can be dangerous enough to lead to anafilactic shock or even death. These allergic reactions can appear even when a non-poisonous spider is involved. They can lead to swellings, fever, dizziness.
