bee sting?

So this morning I woke up there was a little swelling on the bottom of my foot. It wasn't that bad so I went about my morning and ate breakfast and feed Westin. But the swelling seemed to get worse. I could feel the pressure every time I took a step. It didn't look like an ant bite or a mosquito bite. I couldn't see any type of bite marks or anything. Just redness and swelling. It got so bad I started hobbling around and not putting all my weight on it. The bite isn't that bad it is just where it is that is bad. I keep irritating it by walking. So I put some ice on it to help the swelling and hope it is better tomorrow. Roy thinks it might be a spider bite. I hope not. I hear horror stories about spider bites. And we do live in the dirty south. So I guess I will just wait to see how it is in the morning.
