I went to the doctor yesterday for my spider bite because it wasn't getting smaller, just more red and it was starting to look like a bulls-eye rash, which really isn't a big deal unless it's a tick bite, but it still freaked me out enough to call the doctor. The doctor confirmed that it is in fact probably a spider bite due to the fact that it's not healing quickly, there are entrance wounds, and I didn't pull a tick out of my skin. She told me to take some benadryl, which I did once I was in bed for the day. I woke up in the middle of the night and examined my spider bite and the red area had reduced in size, but not very much so I took some more benadryl and now I feel all groggy and incapable of doing anything and it's sort of horrible.
