There are several common causes of foot arch pain, including:
• Plantar fasciitis — Frequently caused by overuse, plantar fasciitis is a common cause of foot pain. While pain from plantar fasciitis is most commonly felt in the heel, some people experience discomfort in the arch area as well. The pain is often described as a sharp, stabbing sensation that’s most intense first thing in the morning upon standing.
• Posterior tibial tendon dysfunction — PTTD (posterior tibial tendon dysfunction) occurs when the posterior tibial tendon wears down or becomes injured. Since the primary job of this tendon is to support a foot arch, PTTD often results in flat feet or fallen arches over time. In fact, PTTD is the most common cause of adult-acquired flat feet. The condition can cause arch pain, making it difficult to walk in some cases.
• Cavus foot — Commonly known as high arch feet, cavus foot can result in arch pain as well as permanent structural changes to the feet in some cases. The pain from cavus foot is typically worse during activities that put stress on the feet, such as walking, running and jumping.
• Overpronation — Pronation is a natural foot action that occurs when walking and running. Some degree of pronation is healthy and necessary for distributing weight properly. However, overpronation can put stress on the arches of the feet and cause pain. Overpronation can also cause the arches of the feet to flatten.
• Flat feet — Also known as flatfoot, flat feet is a condition where the feet have little to no arch. While some people with flat feet never experience any problems, some people with flat feet suffer from foot pain, often in the arch of the foot.
While injury and physical conditions are often the root cause of arch pain in the foot, other factors can also play a role and increase the risk of arch pain. These include:
• Weight — Carrying extra pounds puts additional stress on the feet, which can lead to arch pain in the foot.
• Age — Over time, structural changes can occur in the feet due to years of repeated impact to the feet. For this reason, older adults are more likely to experience foot arch pain.
• High-impact sports and activities — People who regularly participate in sports and activities that put pressure on the feet are more likely to experience arch pain.
