Flexible flatfeet are considered normal in young children because babies are not born with a normal arch. The arch may not form fully until sometime between ages 7 and 10. Even in adulthood, 15% to 25% of people have flexible flatfeet. Most of these people never develop symptoms. In many adults who have had flexible flatfeet since childhood, the missing arch is an inherited condition related to a general looseness of ligaments. These people usually have extremely flexible, very mobile joints throughout the body, not only in the feet. Flatfeet also can develop during adulthood. Causes include joint disease, such as rheumatoid arthritis, and disorders of nerve function (neuropathy).
There are many different causes of flat feet, which can be separated into two main categories. The first category, congenital flat foot, is a condition that one is born with or is predisposed to at birth. This type includes the completely asymptomatic, pediatric flexible flat foot-by far the most common form of congenital flat foot. Flexible means that an arch is present until weight is put on the foot, at which time the arch disappears. This foot type is a result of the fact that all people are born with different physical features. Some people have bigger noses than others, just as some people have flatter feet (of course, there is no known correlation between the two). Any alteration in the many building blocks of the foot can influence its shape.
The most common symptoms of plantar fasciitis include pain on the bottom of the foot near the heel, pain with the first few steps after getting out of bed in the morning, or after a long period of rest, such as after a long car ride. The pain subsides after a few minutes of walking. Greater pain after (not during) exercise or activity.
Flat feet are easy to identify while standing or walking. When someone with flat feet stands, their inner foot or arch flattens and their foot may roll over to the inner side. This is known as overpronation. To see whether your foot overpronates, stand on tiptoes or push your big toe back as far as possible. If the arch of your foot doesn't appear, your foot is likely to overpronate when you walk or run. It can be difficult to tell whether a child has flat feet because their arches may not fully develop until they're 10 years of age.
Non Surgical Treatment
When you first begin to notice discomfort or pain in the area, you can treat yourself with rest, ice, compression, and elevation (RICE). Over-the-counter medications may also be used to reduce discomfort and pain. Rest will allow the tissues to heal themselves by preventing any further stress to the affected area. Ice should be applied no longer than 20 minutes. The ice may be put in a plastic bag or wrapped in a towel. Commercial ice packs are not recommended because they are usually too cold. Compression and elevation will help prevent any swelling of the affected tissues. There are two types of over-the-counter medication that may help with the pain and swelling of arch pain. Acetaminophen (Tylenol) will help with the pain, and a nonsteroidal anti-inflammatory such as aspirin, ibuprofen, or naproxen will help with the pain and battle the inflammatory response. Caution should be taken when using these drugs, and dosage should not exceed the labeled directions. Special care should be taken and a physician consulted if you have a history of stomach ulcers. Those who have chronic medical conditions or who are taking other medications should consult with their doctor regarding the most appropriate type of pain and/or anti-inflammatory medications. Commercial over-the-counter arch supports or orthotics may also help to ease arch pain.
If pain or foot damage is severe, your doctor may recommend surgery. Procedures may include the following. Fusing foot or ankle bones together (arthrodesis). Removing bones or bony growths also called spurs (excision). Cutting or changing the shape of the bone (osteotomy). Cleaning the tendons' protective coverings (synovectomy). Adding tendon from other parts of your body to tendons in your foot to help balance the "pull" of the tendons and form an arch (tendon transfer). Grafting bone to your foot to make the arch rise more naturally (lateral column lengthening).
You may start exercising the muscles of your foot right away by gently stretching and strengthening them. Frozen can roll. Roll your bare injured foot back and forth from your heel to your mid-arch over a frozen juice can. Repeat for 3 to 5 minutes. This exercise is particularly helpful if it is done first thing in the morning. Towel stretch. Sit on a hard surface with your injured leg stretched out in front of you. Loop a towel around your toes and the ball of your foot and pull the towel toward your body keeping your leg straight. Hold this position for 15 to 30 seconds and then relax. Repeat 3 times. Standing calf stretch. Stand facing a wall with your hands on the wall at about eye level. Keep your injured leg back with your heel on the floor. Keep the other leg forward with the knee bent. Turn your back foot slightly inward (as if you were pigeon-toed). Slowly lean into the wall until you feel a stretch in the back of your calf. Hold the stretch for 15 to 30 seconds. Return to the starting position. Repeat 3 times. Do this exercise several times each day. Seated plantar fascia stretch. Sit in a chair and cross the injured foot over the knee of your other leg. Place your fingers over the base of your toes and pull them back toward your shin until you feel a comfortable stretch in the arch of your foot. Hold 15 seconds and repeat 3 times. Plantar fascia massage. Sit in a chair and cross the injured foot over the knee of your other leg. Place your fingers over the base of the toes of your injured foot and pull your toes toward your shin until you feel a stretch in the arch of your foot. With your other hand, massage the bottom of your foot, moving from the heel toward your toes. Do this for 3 to 5 minutes. Start gently. Press harder on the bottom of your foot as you become able to tolerate more pressure.
