How long does it take to heal?

Several months ago (maybe September or October), a shelf fell on my toe at work. Yes, it hurt a lot, but fortunately my toe wasn't broken. My toenail was completely bruised, though, and it still is. How long do you think it will take to heal? I was hoping my toenail wouldn't come off, and it didn't, but my toenail is black and blue.

    That area under your nail that looks bruised is actually dried blood that is trapped between your nail bed and the nail. Once the nail grows out enough you can scrape out the dried blood or it will eventually fall out on it's own. But you will notice that the bruised area is not attached to the nail bed any longer so try to keep it dry if you can. But as the nail grows out it should be reattached to the nail bed where there was no bruise.
