Too much tension in the plantar fascia causes plantar fasciitis and heel spurs. There may be pain in the heel, arch, and other areas of the bottom of the foot, especially in the morning when the calf muscles are tight. Daily tension in the plantar fascia causes re-injury and prevents healing. The tension occurs when standing, walking, running, and any activity that increases weight on the front of the feet (not the heel).
Too much tension in the plantar fascia can be caused by being overweight, stair climbing, lifting heavy objects, pushing a lawn mower, running uphill, and stretching the calf muscles. Athletic tape is applied to the same area as the plantar fascia and reduces tension by preventing the fascia from stretching.
