Diabetic Foot Conditions
Diabetes is the condition in which the body does not properly process food for use as energy. People with Type 1 diabetes cannot produce insulin, which is required for glucose to feed your body’s cells. It is typically caused by the immune system mistaking healthy cells for foreign invaders and destroying the insulin-producing cells in the pancreas. On the other hand, people with Type 2 diabetes cannot respond to insulin properly, and eventually cannot produce enough. The Centers for Disease Control and Prevention reports that over 30 million people in the United States have diabetes, with 1 in 4 having no idea they have it. Surprisingly, diabetes is the seventh leading cause of death in the US. The symptoms of diabetes include frequent urination, fatigue, hunger, and even blurry vision.
Diabetes can also affect the feet as well. Over time, diabetes can cause nerve damage to your feet, which could then lead to symptoms such as tingling, pain and numbness in the feet. Neuropathy can be very dangerous to a person with diabetes, since it prevents them from feeling injuries such as cuts or blisters in the feet, and if not detected early enough, may lead to infection. Neuropathy can also lead changes in the shape of your feet and toes. The best way for people with diabetes to prevent or delay neuropathy is keeping their blood glucose levels in their target range. This consists of eating right, having the correct amount of exercise, and taking medications.
Diabetes can also create calluses and foot ulcers as well. Calluses build up faster and occur more frequently with those affected by diabetes. If there are too many calluses, therapeutic shoes and inserts may be required. It is important to have calluses trimmed by a health professional, as doing it yourself may lead to infections. If these calluses continue to develop and thicken, they can lead to foot ulcers. Foot ulcers are open sores, that appear on the ball of the foot or on the bottom of the big toe. These ulcers can lead to future infections if not treated and may possibly result in losing a limb. It is important to report any ulcers to your podiatrist right away. Your doctor may take x-rays to examine the foot and clean out any dead and infected tissue.
Lastly, diabetes can also lead to poor circulation and peripheral arterial disease (PAD). The poor circulation in the feet and leg area is a result of diabetes narrowing and hardening, eventually slowing down the blood flow in that area. The best way to prevent this is to keep away from smoking and follow your doctor’s advice for maintaining blood pressure and cholesterol. PAD is similar to this complication. PAD is when blood vessels narrow or are blocked by fatty deposits. PAD also increases your risk of heart attacks and strokes and is a common condition to those affected by diabetes. The combination of both PAD and neuropathy may lead to infections and can result in amputation of certain limbs. PAD can be prevented with wearing the proper foot wear and regularly taking care of your feet.
If you want to take care of your feet, you should wash and dry them carefully and perform daily inspections to check for cuts, blisters, or swelling. Any physical activity you partake in should be approved by your health care provider. You should also be sure to wear special shoes if advised to do so by your doctor.
Causes, Symptoms, and Treatment for a Broken Foot
One out of ten broken bones is reported to be in the feet. When an object crushes, bends, or stretches the bone beyond acceptable ranges, bones break. A break in the foot is either a fracture or a straight break.
The location of any break can tell you how the break happened. Toes, for instance, break typically as a result of something being kicked hard and with great force. Heel breaks almost always are a result of an improper landing from a tall height. Twists or sprains are the other two frequent occurrences. As with all usual breaks, they result from unexpected accident or sudden injury. As with stress fractures, breaks form as a process over time from repeated stress on already present cracks. Runners, dancers, and gymnasts are the usual athletes who receive this type of break. Stress fractures result from incredible pressure on the feet. It is no surprise these athletes bear the majority of reported fractures.
Pain, swelling, bruising, and redness are all indicative of the typical symptoms from a broken foot. Severe pain—to the point of not being able to walk—usually depends on the location of the break in the foot. Toes are on the lower scale of pain threshold, but heels are high, as are a few other particular bones. As the severity of the broken foot increases, symptoms like blueness, numbness, misshaping of the foot, cuts, or deformities will become apparent. These symptoms indicate the need to see a medical professional with access to an x-ray facility.
Prior to seeing a specialist, precautions should be taken to reduce pain and swelling. Elevate and stabilize the foot, and refrain from moving it. Immobilization of the foot is the next priority, so creating a homemade splint is acceptable. Keep in mind that while creating a splint, any increase of pain or cutting off blood circulation means that the splint should be removed immediately. Use ice to decrease swelling and relieve pain symptoms.
When dealing with a medical center, the patient should note that the treatment can vary. The treatment will depend on the severity of the fracture and the cause of the break. Crutches, splits, or casts are common treatments while surgery has been known to be used in more severe cases in order to repair the break in the bones.
Tarsal Tunnel Syndrome
Tarsal tunnel syndrome is a condition in which there is a compression of the posterior tibial nerve. The posterior tibial nerve runs along the inside of the ankle into the foot. Tarsal tunnel syndrome is named for the tarsal tunnel, which is a thin space along the inside of the ankle beside the ankle bones. This space contains various nerves, arteries, and tendons, and includes the posterior tibial nerve. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome the tibial nerve is compressed, causing tingling or burning, numbness, and pain.
Common causes of tarsal tunnel syndrome involve pressure or an injury. Injuries that produce inflammation and swelling in or around the tunnel may place pressure on the posterior tibial nerve. Direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or trauma to the tibial nerve, can result in tarsal tunnel syndrome. Diseases that damage nerves, such as diabetes or arthritis, may cause tarsal tunnel syndrome. Those with flat feet are at risk for developing the condition, as the extra pressure and strain placed on the foot may compress the posterior tibial nerve.
Feeling different sensations in the foot at different times is a common symptom of tarsal tunnel syndrome. An afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg. Symptoms are primarily felt on bottom of the foot and/or the inside of the ankle. Symptoms can appear suddenly and may occur due to overuse of the foot.
To diagnose tarsal tunnel syndrome, your podiatrist may examine the foot and tap the posterior tibial nerve to see if symptoms surface. He or she may also order an MRI to determine if a mass is present.
Treating tarsal tunnel syndrome will depend on the decision of your podiatrist. Multiple options are available, however, and can include rest, ice, immobilization, oral medications such as anti-inflammatory drugs (NSAIDS), physical therapy, injection therapy, orthotics, supportive shoes, braces, and surgery.
Sports Related Foot and Ankle Injuries
Foot and ankle injuries are common among athletes and those who exercise frequently. Most of these injuries are non-life-threatening and can heal in weeks with proper treatment and care. Serious injuries, however, require urgent medical treatment.
Common minor injuries include ankle sprains, ankle strains, Achilles tendonitis, plantar fasciitis, stress fractures, and turf toe. An ankle sprain is when the ligaments in the ankle have either become stretched or torn. When the muscle or tendon is stretched or torn, it is an ankle strain. When the big toe is sprained, it is known as turf toe. Achilles tendonitis is the overuse and inflammation of the Achilles tendon. Plantar fasciitis is the inflammation of the plantar fascia and generally occurs from overuse in athletics. Stress fractures are also caused from overuse and are small cracks in the bone.
Achilles tendon ruptures are common, but more serious. This injury occurs when the Achilles tendon, the largest tendon in the body, ruptures. In most cases, this causes severe pain and difficulty walking; some who have experienced this injury have reported, however, no signs or symptoms. A laceration is a deep cut that can occur anywhere on the body. Lacerations on the foot are rarer, but can occur from things like metal cleats landing on the foot.
Treatment options cover a wide range of methods based upon the injury and its severity. Conditions like plantar fasciitis, stress fractures, Achilles tendonitis, turf toe and ankle sprains/ strains can heal on their own without immediate medical care, but seeing a podiatrist to monitor the injury is always recommended. Following the RICE (Rest, Icing, Compression, and Elevation) protocol is generally enough to treat minor injuries. This means resting the foot by either keeping pressure off the foot or not walking at all. Icing the injury will help reduce swelling and pain. Compressing the wound with a wrap will immobilize and help promote healing. Finally, keeping the wound elevated will also reduce swelling and also help the healing process.
It is important to note that even minor injuries can vary in severity, with grade one being a minor injury and grade three requiring urgent care by a podiatrist. Achilles tendon ruptures and lacerations on the foot generally require urgent medical care and treatment options that need a podiatrist. These could include imaging tests, stitches for cuts, rehabilitation, and casts or braces. Every case is different, however, so it is always recommended to see a podiatrist when pain in the foot does not disappear.
How to Get a Proper Shoe Fit
Many people suffer from foot problems because their shoes are poorly fitted. When shopping for a new pair of shoes, fashion usually triumphs over comfortability. A pair of well fitted shoes is essential in preventing foot problems and potential injuries.
Poorly fitted shoes can cause foot issues such as plantar fasciitis, bunions, hammertoes, ingrown toenails, and foot pain. Shoes such as high heels and sandals may cause problems for your feet. These shoes put the foot in an unnatural position for long periods and fail to provide good foot support. It is recommended to not wear either one for an extended period.
When you are trying on shoes, make sure they have enough space for your toes to move around. Shoes shouldn’t be cramped but also shouldn’t have too much room that your foot moves around in them. A snug shoe is a good choice. They should also provide good arch support and cushioning. Athletic shoes tend to offer both good support and cushioning. A degree of flexibility is necessary so they aren’t too stiff or too unsupportive.
If you can wear your shoes for a long period of time without experiencing any discomfort, this is a sign that your shoes fit properly. Do not be too dismayed if the shoe isn’t a perfect fit at first; many shoes take a few days to weeks to properly break in. However don’t expect an uncomfortable shoe to become fitted to your foot.
For those with foot conditions such as flat feet or pronation, orthotics may be helpful or even necessary to prevent foot pain. Orthotics are inserts that are placed in the shoe and provide support and cushioning for the foot. While there are many types of orthotics out there, custom-made orthotics may be necessary depending upon your foot and foot conditions.
Feet change in size over time. It is important to check your foot size over time so that you can make sure you have the perfect fit for your feet. A podiatrist can provide more information on proper shoe fitting and foot orthotics.
