Which condition is characterized by pain in the heel and arch of the foot?

Plantar fasciitis is characterized by pain in the heel and arch of the foot, resulting from inflammation of the plantar fascia, a thick band of tissue that runs across the bottom of the foot. This condition typically manifests as sharp pain, especially during the first steps in the morning or after prolonged periods of sitting, as the fascia tightens and then stretches with movement.

It's closely associated with activities that put stress on the heel and arch, such as running or standing for long durations. Factors like flat feet, high arches, and obesity can increase the likelihood of developing plantar fasciitis.

In contrast, Achilles tendinitis primarily affects the back of the heel and is associated with pain along the Achilles tendon, whereas a foot fracture would present with localized pain and possibly swelling or bruising depending on the nature of the fracture. Bunion formation usually causes pain on the side of the foot near the big toe and does not typically involve heel and arch pain.
