i woke up one morning and noticed that my leg was hurting. I took a look at it and there was a bump there. The follwing day i noticed that there swelling around the bump. And now there is puss inside it like a pimple but the swelling is getting worse and i got most of the puss out but it still feels like theres something inside it. it kind of itches, but not much. My fiance says its a spider bite but im not sure. any ideas?
