I have a small painfull dot on my toe, What is it.?

I have a dot on my big toe it doesn't really look like a pimple and it doesn't have any puss in it. When I press it with my finger it feels like I'm doing it with a pin. It's a bit painfull and I've had it in my toe for a few months now. I just want to know how can I get rid of it.
