Why do I have this stabbing pain in my feet?

Main causes of sharp pain in the foot include Plantar Fasciitis or PF (underside), tarsal tunnel syndrome ( medial foot), neuroma (ball of the foot), and neuropathy. However, plantar fasciitis, or inflammation of the plantar fascia, is a top common cause of stabbing foot pain. Plantar fasciitis is characterized by a stabbing pain in the bottom of the foot or heel.
