Why does my big toe hurt when putting pressure on it although it's not fractured?

Hurt : First , how do you know it is not fractured ? You also don't state where on the big toe it hurts with pressure . Believe it or not there are a lot of different things going on in your big toe and location helps , as well as some background as to what has happened recently , metabolic diseases , activity , etc.

Countless...: Possibilities. See a podiatrist for a more detailed exam and proper diagnosis.
