When the tarsal joint falls, all the nerves and blood vessels can be trapped between the misaligned foot bones. And if you wear tight shoes, the misaligned metatarsal heads can all be cramped together and pinching the nerves in between them. If you keep walking in this condition, the nerves can eventually be damaged and send out a sharp pain.
Treatment: The orthotics that align the ankle bones help the foot bones stay in their proper places. This helps the nerves and blood vessels to position properly. Applying warm and cold packs alternately over the painful area can help the blood circulation in the area and can speed up the healing process.
