Your arches help absorb shock and transfer weight when you're on your feet. The arch of the foot is formed by the bones in the foot and strengthened by ligaments and tendons. These tissues are important when it comes to movement and shifting weight properly from your heels to your toes. When the tissues in the arch of the foot become inflamed it can cause pain and discomfort, even while performing simple tasks such as walking.
The primary cause of arch pain is plantar fasciitis, which is inflammation of the plantar fascia. It's the main band of tissue that connects your heel to your toes. Arch pain can also be caused by direct trauma to the area, such as ligament sprains or bone fractures. Other conditions can also cause arch pain, such as arthritis or flat foot. Most arch pain is felt on the bottom of the foot, especially if the patient has plantar fasciitis. Pain would be felt closer to the heel.
