The outside of both of my big toes have been numb for 3 days now, you have any guesses to why that might be? no other toes are affected.

Nerve impingement: Something is irritating the nerve travelling to this area. Often it is a bunion bump that is rubbing against the shoe. There is a small nerve that is right under the skin and goes on into the big toe. See a podiatrist for an exam, diagnosis and care.

Very common: Problem. Usually comes from a crushed nerve. A pair of shoes may have caused this.
