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.
Flatfoot is a foot disorder that is not as straightforward as many people believe. Various types of flatfoot exist, each with their own varying deformities and symptoms. The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot. Other signs of flatfoot include:
One of the most common types of flatfoot is flexible flatfoot. This variation usually starts in childhood and progresses as one ages into adulthood. Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing. When not standing, the arch returns. Symptoms of flexible flatfoot include:
Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit. X-rays may be taken to define the severity and help determine the treatment option best for your condition. Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices. If nonsurgical methods prove ineffective, surgery may be considered. Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.
Ankle foot orthotics are shoe inserts that offer support to control the placement and movement of the ankle, correct deformities, and compensate for weakness. These inserts are used to stabilize the foot and ankle and provide toe clearance during the swing phase of gate.
Athletes often suffer foot problems because their feet are not being supported within the shoe. Ankle and foot orthotics are custom made inserts that alleviate stress on the foot. However custom orthotics should be prescribed by a podiatrist who specializes in customized footwear and orthotics design. These inserts are used by athletes for different reasons. Runners use orthotics to absorb shock at heel contact and to set up the forefoot for push-off. Basketball players wear them to control their forefeet while jumping and running.
The two main types of orthotics are over-the-counter orthotics and custom-made orthotics. To be eligible for custom orthotics, an examination of the foot and ankle will need to be completed. Afterward, both the foot and ankle will need to be casted and fitted for the proper orthotic. When the fitting process is complete, adjustments can be made to make sure everything fits perfectly.
Over the counter orthotics tend to be more popular than custom fit ones. Athletes who have less severe aches and pains in the foot, ankle or lower back area can use the over-the-counter version of orthotics. Unfortunately, over-the-counter orthotics tend to not work in treating severe injuries or ailments. Whenever you suspect you may need an ankle foot orthotic, you should consult with your podiatrist to determine which type of orthotic is right for you.
Heel pain can be difficult to deal with, especially if you do not know what the underlying cause is. If you ignore your heel pain, the pain can magnify and potentially develop into a chronic condition. Depending on the location of your heel pain, you have developed a specific condition.
One condition is plantar fasciitis. Plantar fasciitis is caused by the inflammation of the plantar fascia, or the band of tissue that connects the heel bone to the base of the toes. The pain from this condition is initially mild but can intensify as more steps are taken when you wake up in the morning. To treat this condition, medication will likely be necessary. Plantar fasciitis is often associated with heel spurs; both require rest and special stretching exercises.
There are various options your podiatrist may suggest for heel pain. Treatment options for heel pain typically include non-steroidal anti-inflammatory drugs (NSAIDS), which may reduce swelling and pain. Other options are physical therapy, athletic taping, and orthotics. In severe cases of heel pain, surgery may be required.
Preventing heel pain is possible. If you are looking to prevent heel pain from developing in the future, be sure to wear shoes that fit you properly and do not have worn down heels or soles. Be sure to warm up properly before participating in strenuous activities or sports that place a lot of a stress on the heels. If you are experiencing any form of heel pain, speak with your podiatrist to determine the underlying cause and receive the treatment you need.
