A sesamoid is a bone that connects to a tendon or muscle instead of another bone. The most common sesamoids are the patella (kneecap) and two bones found under the forefoot. The sesamoids in the foot help to provide the foot with weight-bearing support. Unfortunately, just like another bone, sesamoids can fracture or become inflamed. An inflamed sesamoid is known as sesamoiditis and it’s most often found in athletes.

• Pain at the ball of the foot near the big toe
• Pain when bending or straightening the big toe
• Swelling
• Pain that comes up gradually

• Avoiding any activities that put pressure on the foot
• Taking a pain reliever such as ibuprofen to reduce pain and swelling
• Wearing supportive shoes with ample cushioning
• Applying ice to the foot for 10-15 minutes every few hours
• Avoiding shoes with pointed toes or high heels

The arches of the feet play a role in supporting your body’s weight when standing or in motion. The tarsal and metatarsal bones make up the arches of the feet, also receiving additional support and stability from tendons and ligaments; however, our feet, like the rest of our body, can be affected by infections, disorders, and structural changes that can impact not only the health of our feet but also our mobility. It’s important to recognize the warning signs of arch problems so you know when you need to see a podiatrist.

Arch Pain Causes

If you are dealing with arch pain it is most likely caused by an injury or by structural abnormalities in the foot. For example, those with very high arches as well as those with flat feet may experience arch problems due to these common structural issues.

As a result, there are other factors that could also lead to further arch problems including:

• Being overweight or obese
• Aging
• Plantar fasciitis
• Cavus foot
• Posterior tibial tendon dysfunction

It’s important to understand a little bit more about these common foot disorders and how they could affect the arches of your feet.

Plantar fasciitis

This condition that causes inflammation and microtears in the plantar fascia is also the most common cause of heel pain. Of course, because the plantar fascia (a ligament that connects the toes to the heel bone) also supports the arches of the feet this can also lead to arch pain. This condition is usually the result of overuse and is seen most often in runners. If you have plantar fasciitis it’s important to avoid physical activities until the fascia has fully healed.

Cavus foot

This condition, which affects the structure of the foot, leads to excessively high arches. People who’ve had a stroke, as well as people with certain conditions such as cerebral palsy may be more likely to develop cavus foot. This problem causes arch pain when standing or walking and can increase the risk for ankle injuries. Your podiatrist may choose to treat cavus foot through custom-made orthotics (shoe inserts), bracing, or by recommending specialized and supportive footwear.

Posterior tibial tendon dysfunction

The posterior tibial tendon runs from the calf muscles to the inner portion of the foot. This condition leads to changes in the tendon, which in turn affects its ability to support the arches of the foot. Flat feet can be caused by posterior tibial tendon dysfunction, and this is often the cause of flat feet that develop in adulthood. Like the other conditions above, treatment for PTTD usually involves bracing, orthotics, or providing custom devices that provide additional support to the arches of the feet.

If you are experiencing foot pain, swelling or other problems that affect mobility then it’s time that you turned to a podiatrist for care. Conditions and injuries that don’t respond to rest and at-home care may require more advanced treatments and therapies.
