Yesterday morning, I hit my pinkie toe on my bedframe, and it left a good-sized cut/puncture that went slightly underneath the toenail. The toe was was VERY tender to walk on all day, but there wasn't any bruising or swelling.

Now, about 36 hours later my toe is red and swollen, and my entire foot is aching with a slight tingling feeling.

Is this an infection? Or did I just sprain my toe?
