I was bitten by a spider (unknown type) in late October. I went to the doctor due to the site being very inflamed and swollen. I took a ten day round of antibiotics and a steroid injection. It healed well with no problems at all. Now, Nearly three months later, a huge blister with redness around it has come up in the exact place i was bitten. Why did this occur?
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.
