According to Mayo Clinic, spider bites are often itchy and produce a red, raised bump at the site of the bite. A spider bite should be cleaned using warm soapy water, and a cold ice pack can be applied to the area to reduce inflammation and pain.
Over-the-counter pain relievers can also alleviate any associated pain, according to Mayo Clinic. If the spider bite is from a black widow or brown recluse spider, it may cause additional symptoms, such as cramping, sweating and extreme pain. If one of these, or any other poisonous spider, is suspected, contact a doctor for additional treatment.
