[/INST] HelloWelcome to Chat Doctor, Spider bites are actually rare occurrences and bites from most spiders cause local redness, irritation and pain that usually can be treated at home. These local reactions usually resolve without treatment over a period of 7-10 days. I would suggest you to follow Wash the site of the spider bite well with soap and water. Apply a cool compress or ice pack over the spider bite location. Over the counter pain relievers may be used to relieve symptoms. Thank you. </s>
