I saw the thread on Target sleepers and felt I had to make a PSA about sleepers that are too small. (TL;DR: Never wear a footed sleeper that is too small for your feet, even for a short time. It could cause real damage to your feet.)
Last winter, I bought a footed sleeper from Target in boys size XL, the largest available size. I wasn't sure if I'd fit into it, but it was cheap and cute, so I thought I'd give it a try.
When I got the sleeper home, I did manage to squeeze into it, barely. The feet in particular were very tight, tight enough that they made my big toenails hurt. I figured it wouldn't kill me to spend some time in mildly uncomfortable clothes, and I wanted to get my money's worth, so I wore the sleeper to bed a couple of times.
A few months later, I noticed that it had been a long time since I cut my left big toenail. A couple more months later, the skin around my toenail started looking red and a little painful. I thought maybe it was infected, but maybe the infection would go away by itself. That Friday afternoon, as I left work, I couldn't walk to my car without limping.
I decided to go to the emergency room, where after a long wait I was given a topical antibiotic, which didn't cure the infection. My primary care doctor gave me an oral antibiotic, which also didn't cure the infection. I finally went to a podiatrist. He told me he'd need to remove part of the nail. When I explained to him I thought the toenail might have been injured by wearing footed pajamas, he said the whole nail would have to go.
Happily, the procedure was quick and painless (thanks, Lidocaine!) but the whole ordeal was fairly icky. The toenail is still growing back. It's too soon to tell whether I'll get a healthy nail.
Morals of the story:
1) Feet are fragile. Do not wear sleepers that are too small for your feet, no matter how cute they are.
2) If it's Friday morning, and you're not sure if you need to go to the doctor to have something looked at, just go.
3) Always be up front with your doctor about what may have caused the condition you have. If I had been too shy to tell my podiatrist I had worn footed PJs, I might still be dealing with this problem.
