"Is heel pain the same as plantar fasciitis? If the pain is located on the bottom of the heel, it is most likely plantar fasciitis. The plantar fascia is a long ligament that connects the heel bone to the front of the foot. It can get irritated at its attachment to the heel bone. The plantar fascia helps to support the arch. This condition can occur when a person wears unsupportive shoes or flip-flops, spends a significant amount of time barefoot, or injures the heel. The pain can be achy, throbbing, or even sharp. Pain first thing in the morning or after resting is a sign your heel pain may be plantar fasciitis. Sometimes, a heel spur can be present, but understand, the spur does not cause the pain. It is the attachment of the plantar fascia being inflamed."
