Pain in the arch of the feet — plantar fasciitis — is the most common cause of foot pain. It can be relieved, often permanently, by finding the trigger points in the calf and in the arch of the foot.
Anyone who stands for long periods of time or works on their feet most of the day is susceptible to pain from trigger point #3 — dock workers, chefs, retail employees, cashiers, medical personnel and hair dressers.
