__The fusiform gyrus is also in the frontal lobe, and also plays an interesting role in language processing in the brain. This area helps you recognize words and classify things within other categories. Damage to this part of the brain can cause difficulty in recognizing words on the page.
Damage to the nerves in the leg and foot are another common cause of numb feet. Damage to the peripheral nervous system is known as peripheral neuropathy and affects how signals are transmitted from the nerves to the central nervous system, commonly causing foot numbness.
Inflammation of the plantar fascia can also cause this pain -- normally at the bottom of the heel. Known as plantar fascitis this can cause your symptoms. Both of these occur due to overuse of the foot, often with an abnormal foot arch. Often, shoe inserts or orthotics are needed.
