There is a sharp pain when i walk, could this mean be heel/foot is broken?

Plantar fasciitis.: The most common cause of heel pain is plantar fasciitis: an inflammation of a thick band of tissue that helps hold up the arch of your foot. It attaches to your heel bone, and is usually the most painful during the first few steps in the morning, or after sitting a long time and then standing quickly. Check with your podiatrist to rule out nerve damage, stress fracture, or other bony problems.
