Neuropathy is a condition in which the nerves in the body become damaged from a number of different illnesses. Nerves from any part of the body, including the foot, can be damaged. There are several forms of neuropathy including peripheral neuropathy, cranial neuropathy, focal neuropathy, and autonomic neuropathy. Furthermore there is also mononeuropathy and polyneuropathy. Mononeuropathies affect one nerve while polyneuropathies affect several nerves. Causes of neuropathy include physical injury, diseases, cancers, infections, diabetes, toxic substances, and disorders. It is peripheral neuropathy that affects the feet.

The symptoms of neuropathy vary greatly and can be minor such as numbness, sensation loss, prickling, and tingling sensations. More painful symptoms include throbbing, burning, freezing, and sharp pains. The most severe symptoms can be muscle weakness/paralysis, problems with coordination, and falling.

Podiatrists rely upon a full medical history and a neurological examination to diagnose peripheral neuropathy in the foot. More tests that may be used include nerve function tests to test nerve damage, blood tests to detect diabetes or vitamin deficiencies. Imaging tests, such as CT or MRI scans, might be used to look for abnormalities, and finally nerve or skin biopsies could also be taken.

Treatment depends upon the causes of neuropathy. If the neuropathy was caused by vitamin deficiency, diabetes, infection, or toxic substances, addressing those conditions can lead to the nerve healing and sensation returning to the area. However if the nerve has died, then sensation may never come back to the area. Pain medication may be prescribed for less serious symptoms. Topical creams may also be tried to bring back sensation. Electrical nerve stimulation may be used for a period of time to stimulate nerves. Physical therapy can strengthen muscle and improve movement. Finally surgery might be necessary if pressure on the nerve is causing the neuropathy.

If you are experiencing sensation loss, numbness, tingling, or burning sensations in your feet, you may be experiencing neuropathy. Be sure to talk to a podiatrist to be diagnosed right away.

A new treatment for fungal nails, or onychomycosis, which has grown in popularity in recent years, is laser treatment. Laser treatment involves the use of a laser that kills fungus in the toenail with heat. Laser therapy causes no side effects and does not affect nearby healthy tissue.

Toenail fungus afflicts almost 10 percent of the U.S. population and is more common among the elderly. The most common symptom of toenail fungus is the discoloration and thickening of the nail. The nail can also become brittle and a foul smell may be produced. In rare cases, pain might be present. While it is not a serious condition, it can lead to a perception of disgust amongst those it affects. There are several different fungi that cause fungal infections. These include dermatophyte, yeast, and mold. The most common of these is dermatophyte.

Diagnosis for fungal nails involves a podiatrist utilizing microscopy and fungal cultures. This will allow the doctor to determine whether it is a fungus or another condition, such as lichen planus, psoriasis, nail damage, and onychogryphosis.

Fungus in the nails can be hard to get rid of with over-the-counter drugs. This is due to the nail being hard and protective, with fungus able to slip between the nail bed and plate. Furthermore the slow growth of the nail increases the difficulty of fungus going away. Laser treatment seeks to get around this by directly penetrating through the nail and killing the fungus. The laser is used on each infected nail for a couple of minutes. Patients then typically return several weeks or months later for another laser treatment. During this time the podiatrist will routinely observe the foot and infection. It is also recommended to wear clean socks and shoes and allow the feet to dry and breathe to prevent toenail fungus.

Laser treatment is still a relatively new treatment and not all podiatrists have laser machines. Ask your podiatrist if they do laser treatment for toenail fungus and if it is right for you.

A congenital foot problem is a problem affecting the feet, toes, and/or ankle that a child is born with. Several issues with a child’s feet can occur congenitally. Such problems include clubfoot, vertical talus, tarsal coalition, polydactyly, macrodactyly, and cleft foot. Some of these problems have a genetic basis, with someone in their family history having a gene causing the condition, and some are simply an anomaly.

The following are specifics about a few of these conditions:

-    Clubfoot, also called congenital talipes equinovarus or talipes equinovarus, is When the tendons of the foot shorten, the bones are of an unusual shape, and the Achilles tendon is tight, causing an inward and downward pointing of the foot. The soles of the feet might also face each other. In most cases of clubfoot, both feet are affected. If not treated, the affected child will walk on the sides of their feet or ankles.

-    Polydactyly is a condition where the child has more than five fingers or toes on either or both feet. Presentation usually consists of a nubbin or small lump of tissue without a bone, a toe that is partially formed but has no joints, or an extra toe.

-    Vertical talus is where the talus bone forms in the wrong position, other bones in the foot do not line up properly, the front of the foot points up, and the bottom of the foot is stiff, has no arch, and usually curves out. This can occur in one or both feet and if left untreated, can lead to serious disability or discomfort as the child grows.

-    Tarsal coalition is when there is an abnormal connection of two or more bones in the foot leading to severe, rigid flatfoot. The tarsal bones, located toward the back of the foot and in the heel, are the ones affected. This condition is often present at birth, but signs of the disorder usually come on in early adolescence.

-    Cleft foot is a rare condition where the foot has missing toes, a V-shaped cleft, and other anatomical differences. Surgery can often help improve the foot’s function since the heel remains normal and is what is most needed for walking. The main issues with this affliction are whether the affected foot can fit into a shoe and the shape and appearance of the foot.

-    Macrodactyly is when the toes are abnormally large due to overgrowth of the underlying bone or soft tissue. Having this condition makes it harder for the child to use the affected foot for certain activities.

Orthotics are shoe inserts that are meant to correct an irregular walking gait or provide cushioning to the feet.  Orthotics come in a variety of different models and sizes, including over-the-counter and customizable variants. Customizable orthotics can be shaped and contoured to fit inside a specific shoe and are typically prescribed through a podiatrist who specializes in customized footwear and orthotics design and management.

Orthotics are beneficial because they can help prevent injuries from occurring and provide cushioning to keep pain levels down to a minimum. They also allow for the correct positioning of the feet. Orthotics can act as shock absorbers to help remove pressure from the foot and ankle. Therefore, orthotics can make bodily movements, such as walking and running, become more comfortable as well as help prevent the development of certain foot conditions.

Orthotics alleviate pain and make the foot more comfortable by slightly altering the angle at which the foot strikes the ground surface, therefore controlling the movement of the foot and ankle. Orthotics come in different variants and can be made of various materials. To determine what type of orthotic is most suited to your feet and your needs, it is best to consult your podiatrist. He or she will be able to recommend a type of orthotic that can help improve your foot function or prescribe a custom orthotic to best fit your feet.
