Is This A Typical Spider Bite?

I live in Nebraska, and about three days ago, I was bitten by a spider, presumably in my sleep. At first, I didn't notice anything, but then later that day, I felt a very slight itching. I glanced and saw a very very faint red spot, and immediately knew it was a bug bite of some kind. No pain, and the itching was very very miniscule. The next day, I noticed the tiny pustule that happens with spider bites so I knew it was a spider that got me. Then later that night, I began to experience swelling. The swelling at first wasn't too bad, and was mostly around the bite site (which is about two inches or so above the ankle). However, as yesterday progressed into today, the swelling extended to other places. Mostly around my ankle and some of my foot, it's swollen like a balloon and hot, hard, and painful to walk on. The swelling is also going up my leg a tad, though not much. There is no white halo associated with recluse bites, and not to mention we don't have very many here in Nebraska anyways. It's just raised and red. I do not feel sick, dizzy, nauseous, etc., besides a bit of fatigue I felt when I first started swelling up, which I do not feel now. I know I see a ton of parson spiders and common house spiders here though. Mostly, it's just a very very swollen, very painful leg.
