Symptoms of spider bites can include pain, swelling, itching, muscle pain, difficulty breathing, nausea, vomiting, and in severe cases, blisters or ulcers.
Typically, a spider bite looks like any other bug bite — a red, inflamed, sometimes itchy or painful bump on your skin — and may even go unnoticed. Harmless spider bites usually don't produce any other symptoms. Many skin sores look the same but have other causes, such as a bacterial infection.
Its spider bite may cause the victim to experience the following signs and symptoms according to the Government of Western Australia: Intense localised pain. Five minutes after the bite: a feeling of swelling and sweating. One hour after the bite: pain and swelling over the body, headache, nausea, and vomiting.
Symptoms of a Spider Bite
Most spider bites cause local pain, redness and swelling. It's much like a bee sting reaction. A few spiders (such as the Black Widow) can cause a more severe reaction.
Bites from many Australian spiders can cause localised reactions, with symptoms such as swelling and local pain at the site of the bite, sweating, nausea and vomiting and headaches.
Many skin sores attributed to spider bites turn out to have been caused by bites from other bugs, such as ants, fleas, mites, mosquitoes and biting flies. Skin infections and other skin conditions, even burns, can be mistaken for spider bites.
If you do receive a venomous bite, within a few hours, it will become red and hard, similar to a mosquito bite, and within a day or two it will develop blisters. After the blisters open, a scab typically forms, along with a rash that often looks like a target or bull's-eye.
Bites from midges, mosquitoes and gnats often cause small papules (lumps) to form on your skin that are usually very itchy.
Cephalexin, sulfamethoxazole-trimethoprim, or clindamycin are usually the choices of antibiotics that can treat cellulitis, including when it's from a spider bite.
If you do get bit, your symptoms will vary, depending on what type of spider bit you. Generally, your skin may be raised, red, and itchy at the location of the bite. These symptoms may last several days but typically go away on their own.

The bite may produce the following symptoms: Intense localised pain, with swelling and sweating starting five minutes after the bite. Pain and swelling may be experienced over the body after about half an hour. Headache, nausea and vomiting may occur after one hour - profuse sweating is common.
Bite Appearance: Red welts (small, flat or raised), swelling, red rash, or bites can appear in tight lines of multiple, small, red marks. Bite Symptoms: Initial burning sensation, itching, it is possible to have no reactions, and bite goes unseen. Notes: May go unnoticed for a few days. One bug may bite multiple times.
There are three likely sources for bug bites at night — spiders, mosquitos or bed bugs. Spiders and mosquitos usually find their way into your home — and into your bedroom — during the warmer months.
Bed bugs bite each person differently, but the most common appearances of bed bug bites include: Raised bumps in a line, zigzag or random pattern. Pimple-like bump with a dark red center and skin tone lighter than normal surrounding it. Round bump on your skin containing a clear fluid (blister).
