I slammed my big toe into a solid wood chair. I instantly felt extreme pain but just toughed it out. It's now about seven hours later and my toe still hurts, it's extremely swollen, and bruised in a few places. I'm pretty sure I broke it but I'm not sure. Also, what should I do if it is broken/fractured/etc?

It's very difficult to walk. I've been using a cane to relieve some of the pressure.

And I can point my toe downwards, but pointing it up or bending it just doesn't happen
