Blister

I got a blister on my heel. This happened a week ago, and it healed. Naturally. Because it's a blister, not a permanent disfigurement. But it healed, and it felt all callus-y and fine. I got the blister from my black, AE heels. Then today, in light of the first blister healing, I wore the shoes to school again.
Bad idea.
Now, the left foot, which had the original blister, was fine all day. Not even a bit of redness on the skin. I was walking to class, climbing stairs, all was dandy. Until this quiet little announcement floats over my ears, "Hey, Shae, your foot is bleeding." What? Impossible, I think. I look at the heel of my left foot, which had a blister in the first place. It was fine.
"No," my friend says again. "Your RIGHT foot." Oh. Right. I have two feet, and now I have blisters on both. Except this right-footed blister is the blister of hell. It's the width of a quarter, the length of one of those jumbo Pink Pearl erasers. And also, it was bleeding like nobody's business. You know how sometimes after a flu shot, your arm freaks out and you've lost a million litres of blood in a half minute (a hyperbole, to be sure, but bear with it)? That's what my foot looked like. I got a band-aid from the nurse and it kept bleeding for ten minutes! I bled thru the first band-aid and it stopped sticking to me, the cloth was too wet. So I had to go back and get another band-aid, and change my shoes at the dorm.
The only open-back shoes I own are seventeen centimetres tall. Isn't it sad the seventeen centimetre tall shoes are the more practical choice?
Also, the blood stained my black AE heels. Gross. I had, like, a permanent scab on one of my shoes. Isn't it going to, like, go bad or something? And smell funky? Ferment? I don't know. Maybe it's fine. I rinsed the shoe, it's just still red.
I mean, should I be concerned about that? I dunno.
