The most simple cause of numbness in the foot is positional. We have all experienced numbness in the foot at one time as a result of sitting, standing or lying in the same position for too long. This can block off the blood supply to the foot, causing it to feel numb. This type of numbness is easily alleviated by changing position and as the blood flow returns to the foot, the feeling of numbness disappears.
Disorders of the nerves to the feet may cause numbness and burning sensation in the feet known as peripheral neuropathy. Plantar warts commonly found on the bottom of the foot are caused by a virus and can cause irritation. Athlete's foot, which is caused by a fungus, also can lead to foot irritation.
