Numbness on right pinky toe and side of foot up until ankle bone. no pain at all or other discomfort. been this way for 2 days. what do i do?

Nerve irritation.: The area you are describing seems to be describing a specific nerve route. The problem might involve irritation of a nerve in the foot. Less possibly, would involve irritation of a nerve exiting the spine in the back area. With no history of injury, look at your shoes and see if there is a possibility of the one being too tight. To remove all doubt, have the problem evaluated by a specialist.
