In foot care, vascular testing may be required in the diagnosing and treatment of certain podiatric conditions. Vascular testing is particularly relevant for patients with high-risk diabetes, poor circulation, peripheral artery disease (PAD), and chronic venous insufficiency (CVI). Procedures typically involve the examination of blood vessels throughout the body for blockages or buildup.

Vascular testing is very important for the diagnosis of various conditions, including peripheral artery disease and chronic venous insufficiency, as these conditions can greatly affect one’s quality of life and cause pain in the lower limbs. Circulatory problems in the feet and ankles can reflect issues throughout the body, making testing of the blood vessels pertinent.

Testing methods vary between practitioners and can be specific to certain foot and ankle problems. Modern technology has brought about the ability to perform vascular testing using non-invasive methods, such as the cuff-based PADnet testing device. This device records the Ankle-Brachial Index (ABI)/Toe-Brachial Index (TBI) values and Pulse Volume Recording (PVR) waveforms. Contact your podiatrist to determine what vascular testing is available for your needs.

Ankles are joints that connect bones in the feet with bones in the lower leg. They are comprised of bones, ligaments, muscles, tendons, blood vessels, and nerves. The ankle joint allows the foot to move side-to-side, as well as up-and-down.

Ankle pain can be caused by a variety of conditions, but is most commonly due to soft tissue injuries such as ankle sprains and strains. 

An ankle sprain occurs when one or more of the strong ligaments that support and stabilize the ankle become overly stretched or even torn if the ankle rolls, turns, or twists awkwardly. Depending on the grade of sprain (mild-moderate-severe), there will be varying degrees of pain, swelling, and restricted range of motion, along with tenderness, bruising, and ankle instability. There may even be an audible popping noise at the moment of injury.

Ankle strains can sometimes produce similar symptoms of pain, swelling, and loss of motion, however, they are due to overly stretched muscles and tendons—not ligaments. Ankle strains may also cause muscle cramps in the feet, calves and shins.

Ankle fractures are another common source of ankle pain and occur one or more of the three bones in the ankle become fractured (broken). These breaks can be stress fractures (due to repetitive stress) or traumatic fractures (due to an acute injury). Depending on where and how severe the fracture is, symptoms can include pain and swelling that can sometimes spread up to the knee, bruising or discoloration, and an inability to bear weight. A visible deformity or exposed bone may occur in severe fractures.

Various forms of arthritis may also cause ankle pain. Rheumatoid arthritis (RA) causes the immune system to attack healthy joints, like the ankle joint, by mistake, causing stiffness and swelling in both ankles. Osteoarthritis occurs when cartilage covering the ends of bones wears down, causing the bones to rub against each other. This results in pain, stiffness, and reduced range of motion in the ankle. Gout is a form of arthritis where excess amounts of uric acid in the bloodstream crystallize and build up on joints, causing severe pain and swelling. Reactive arthritis causes joint pain and swelling in the ankle in response to an infection in another part of the body.

Other forms of ankle pain include bursitis (an inflammation of a cushioning bursa sac between tendons and bone), scleroderma (a thickening of connective tissues), chronic ankle instability (caused by improperly healed ankle sprains), Achilles tendon injuries, flat feet, or an infection in the ankle.

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.

Our feet are important in our everyday lives. The problem is that we tend to neglect them. When this becomes a habit, it can cause significant trouble. Ignoring foot problems can mean pain, limited mobility, and expensive doctor's visits. On the other hand, if feet are cared for and looked after regularly, they will perform without pain or complication.

Routine hygiene is the most basic way to care for the feet. Wash and dry them thoroughly daily. Remember to get between the toes and keep the toenails trimmed and short. If the feet feel dry or there are signs of dryness or cracking, use a moisturizer designed for the feet.

When using moisturizer on the feet, try to avoid applying between the toes. If cream or lotion sits too long, they can cause fungal and bacterial growth. When moisturizer is used between the toes, it can also cause the skin to soften too much.

Shoes are also an important aspect of foot care. When one is picking out shoes, make sure they are the correct size. Shoes need to be snug, but not too tight. On the other hand, if shoes are too loose they can cause foot problems as well. It is highly recommended that shopping for new shoes be done later in the day. The reason for this is that the feet will have settled and swelled to their full size by then. To keep your feet at their most healthy, avoid wearing high heels or flip flops too often. Instead, choose shoes that are good for your feet. Good shoes pad the soles of your feet and support the arches and ankles.

Socks should also be worn daily with closed-toe shoes. They may feel hot during the summer months, but they absorb sweat and moisture off the feet. Without socks, the build-up of sweat in a closed-toe shoe can cause fungal problems and athlete's foot.

The best thing to remember in every day foot care is that shoes do make a difference. If you spend a lot of time on your feet, make sure that your shoes show no signs of wear. Shoes should offer ample support for the arches and the overall foot. Additionally, try to make foot cleaning and maintenance a daily habit. If you keep these things in mind, your feet will stay healthy and safe.

During your lifetime, you will probably walk about 75,000 miles, which is quite a lot of stress to put on your feet. As you get older, the 26 bones and 30 joints in each of your feet will lose flexibility and elasticity. Your foot’s natural shock absorbers will wear down as well. Having arthritis added to this mix only makes matters worse. Your joints will become distorted and inflamed, which is why arthritic foot care needs to be something to think about every day.

When dealing with arthritis, having additional foot complications, such as bunions, hammertoes, or neuroma, can be a serious detriment. To avoid these, buy well-fitting shoes with a lower heel and good support. Arthritis causes you to lose your arch, so having shoes with good arch support is also highly recommended.

Aside from getting good arch support, the shoes need to fit comfortably and properly as well. A good place to start is by leaving a finger width between the back of the shoe and your foot to gauge proper size. It is also helpful to have a square or rounded toe box in the front to provide even more comfort. Another thing to look for is a rubber sole that can provide a cushion and absorb shock as you walk. This adds flexibility to the ball of your foot when you push off your heel to walk.

Exercise is another key aspect of arthritic foot care. Exercise not only strengthens and stretches your muscles and joints, but helps to prevent further injury and pain as well. Stretching the Achilles tendon, the tendon located in the back of your heel, will give you added mobility and reduce pain due to stress. Another thing you can do is massage your feet, kneading the ball of your foot as well as your toes from top to bottom.

Stretching the Achilles tendon is a simple exercise that you can do at home anytime. Lean against the wall with your palms flat against the surface while placing one foot forward, towards the wall, and one foot behind you. Bend your forward knee towards the wall while keeping your back knee locked straight, and make sure both your heels are completely touching the ground at all times. This will stretch your Achilles tendon and calf muscles as well. You will feel the stretch almost immediately. You can also stretch your toes in a couple ways. One involves taking a rubber band and wrapping it around both your big toes while your heels remain together. Then, pull them apart to stretch your big toe. You can also place a rubber band around all the toes of one of your feet. Then, try to separate each individual toe, stretching them all.

A final step you can take to help your arthritis is taking non-steroid, non-inflammatory drugs or topical medicines with capsaicin. Unfortunately, there is no complete way to remove all of your arthritic pain. However, following some of this advice can go a long way in staying as pain-free as possible.
