What kind of bug bite is this? ?

• Last night I was in my backyard, with sandals on. While I was sitting on the floor, I saw a spider crawl from around me, it was brown and small. The. When I went inside I noticed a small insect bite on my inner ankle, it was itching. I assumed it was the spider that crawled from under me, so I just washed it with soap and water and put alcohol on it. Now this morning I wake up and it's bigger! Is this a spider bite or something else? And how should I go about treating it?!

• Answer:

  it's a spider bite. it's getting bigger because it's swollen, don't worry to much about it, it will go down within a week, bug bites normally tend to stick around for a while. Use antiseptic wipes to clean it a couple times a day to prevent it from getting infected, and don't pick at it!
