Winter Tips for Cold Feet

Brrr! Winter is in full force here in the valley and that means it’s COLD. During this time of the year we often pile on layers to protect our core but tend to forget about our extremities. If you’re looking for tips on how to keep your feet warm this winter, Shenandoah Podiatry can help.
Socks made from natural fibers – like wool – should be worn because they have moisture-wicking properties. This helps to prevent fungus which grows best in warm, damp places. Leather shoes can also keep your feet warm because leather has natural insulating properties. If you choose to wear insulated boots, be sure that they aren’t too tight as this can cause ingrown toenails. Avoid electric socks and other heated inserts because they can be dangerous especially if there’s an underlying reason for your cold feet.

Aside from winter weather, cold feet can be caused by a number of serious ailments that should be addressed right away. If our feet are cold year-round, we might be especially quick to write it off as normal during the winter. Unfortunately, cold feet can be indicative of a more serious problem and should never be ignored.

Peripheral vascular disease (PVD) or poor circulation is a common culprit. Blood helps to keep us warm and without proper circulation our bodies direct heat to our core and away from out feet. If you smoke or have diabetes, you have an increased risk of developing PVD which can make it harder for small cuts and ulcers to heal properly. This is why it’s so important to see a podiatrist right away if one of these sores develops.
Diabetes can also put you at risk for chilbains or ulcers of the toes and feet after cold exposure. If you experience redness and swelling in your toes after being outside and it doesn’t go away once they’ve warmed, make an appointment to see us right away.
We hope that you’ll follow these tips and be on the lookout for these possible conditions. If you do, you’ll find it easier to keep your feet warm this winter which is important because warm, dry, pain free feet are healthy feet.

Corns

For more information visit our website http://www.roanokefoot.com/


Corns are hyperkeratotic papules of the skin. They are also known as clavi. These lesions can be painful.

They develop due to excess pressure on the bony prominences of the feet and toes.


Factors that contribute to the formation of corns include:

Abnormal foot mechanics

Foot Deformities

High Activity Levels

Peripheral Neuropathy


Corns are often seen in:

Athletes

Elderly Patients

Diabetic Patients


Types of Corns:

Hard Corn (Helloma Durum)- Commonly found over the joints of toes.

Soft Corn (Helloma Molle)- Found in interdigital locations and has a macerated texture.

Periungual Corn- Found near the edge of a nail.


Presentation:

Corns present with a growth on the foot or toes. Pain is associated with walking or wearing shoes.

Direct pressure generally cause pain to the affected area.

After debridement a corn may have a central plug of skin.



Intrinsic causes:

Foot deformities such as a bunion or a hammertoe

Extrinsic causes:

Activity

Poor fitting shoe gear


Work Up:

X-rays of the feet while weight-bearing can help identifying bony prominences.

Pressure studies- Can help locate the exact location of pressure.

After trimming the lesion the examiner can attempt to determine if the lesion is a corn, callus, or wart.


Treatment:

Hard corns- Pare or debulk the lesion utilizing a small blade. Removal of the centralized plug.

This should be performed regularly in high risked patients such as diabetics.

Regular debridement might decrease the risk of ulceration.


Soft corns- Hygiene is important to decrease the chance of infection. The patient should wear a pair of properly fitting shoes.

The use of an antifungal or antibacterial powder may be helpful.

Toe spacers can also be beneficial.


Other treatment:

Keratolytics such as salicylic acid, urea cream, or lactic acid cream may be prescribed by your doctor.

Good fitting shoe that match the length and width of the patient's feet.

The use of a pumice stone for careful debridement.

The use of good foot hygiene.

The use of a silicone sleeve.

Orthotics


Surgical care:

If conservative treatment fails surgery may be indicated to remove bony prominences.

Rheumatoid Arthritis

Rheumatoid arthritis is a chronic systemic inflammatory disease of unknown cause that primarily affects the peripheral joints in a symmetric pattern.

RA causes joint destruction and thus often leads to considerable morbidity and mortality.

Why do people Get RA ?

- An infectious etiology has been speculated
- Associated with a number of autoimmune responses
- Whether autoimmunity is a secondary or primary event is still unknown
- RA has a significant genetic component

Frequency :

The worldwide incidence of RA is approximately 3 cases per 10,000 population

Mortality/Morbidity:

- Daily living activities are impaired in most patients
- Life expectancy for patients with RA is shortened by 5-10 years

Signs and Symptoms:

- Morning stiffness
- Arthritis of 3 or more joint areas
- Arthritis of hand joints - At least one swollen area
- Symmetric arthritis with simultaneous involvement
- Rheumatoid nodules

Progression of RA :

Stage 1 (early RA)

- No destructive changes observed on x-ray
- Radiographic evidence of osteoporosis possible

Stage II (moderate progression)

- Radiographic evidence of periarticular osteoporosis with or without slight subchondral bone destruction
- Slight cartilage destruction possible
- Joint mobility possibly limited; no joint deformities observed
- Adjacent muscle atrophy
- Extra-articular soft tissue lesions (eg, nodules, tenosynovitis)

Stage III (severe progression)

- Radiographic evidence of cartilage and bone destruction in addition to periarticular osteoporosis
- Joint deformity
- Extensive muscle atrophy

Stage IV (terminal progression)

- Criteria of stage III
- Fibrous or bony ankylosis - stiffness of a joint due to abnormal adhesion and rigidity of the bones of the joint

Remission:

Remission of RA - Five or more of the following conditions present for at least 2 consecutive months:

- Duration of morning stiffness not exceeding 15 minutes
- No fatigue
- No joint pan
- No joint tenderness or pain with motion
- No soft tissue swelling in joints or tendon sheaths
- ESR of less than 30 mm/h for a female or less than 20 mm/h for a male

Lab Studies:

No pathognomonic test is available to help confirm the diagnosis of RA. The diagnosis is made using clinical, laboratory, and imaging features. Clinicians will analyze the following:

- Markers of inflammation, such as ESR and CRP
- Synovial fluid analysis
- Rheumatoid factor - Present in approximately 60-80% of patients with RA over the course
- Antinuclear antibodies - These are present in approximately 40% of patients with RA

Treatments:

Disease-modifying antirheumatic drugs:
- Leflunomide (Arava)
- Methotrexate
- Sulfasalazine
- Etanercept (Enbrel)
- Infliximab (Remicade)

Nonsteroidal anti-inflammatory drugs

Analgesics

Glucocorticoids

Immunomodulators:

- Anakinra (Kineret)
- Abatacept (Orencia)

A Hiking We Will Go

I saw my first through hikers off the AT last weekend at Kroger-Daleville while doing my weekly grocery shopping. It got me thinking about all of the people that have limped into my office off the trail over the years.

Walking up and down steep hillsides and tramping through wet, slippery fields and wooded areas puts stress on the muscles and tendons in the feet and ankles, especially if you haven't conditioned properly before hitting the trail. Also, many don't realize that sneakers aren't the best choice for extended hiking and hunting. Had some of my patients worn sturdy, well-constructed hiking boots, they wouldn't have suffered sprained ankles or strained Achilles tendons.

Make the investment in top-quality hiking boots. Strong, well insulated and moisture-proof boots with steel or graphite shanks offer excellent ankle and foot support that helps lessen stress and muscle fatigue to reduce injury risk. The supportive shank decreases strain on the arch by allowing the boot to distribute impact as the foot moves forward. So if a boot bends in the middle, don't buy it.

In wet and cold weather, wearing the right socks can help prevent blisters, fungal infections. Synthetic socks should be the first layer to keep the feet dry and reduce blister-causing friction. For the second layer, wool socks add warmth, absorb moisture away from the skin, and help make the hiking boot more comfortable.

Don't ignore pain and hope that it will go away. If you are out on the trail, try and take a break to see if the pain subsides. As soon as you are able, make a visit to your podiatrist to determine the cause of your pain. Remember, pain is your body letting you know there is something wrong.

Summertime Injuries

With summer sporting events beginning, as podiatrists we begin to see increased foot and ankle injuries in athletes and runners. Some common injuries that will be seen are stress fractures. Stress fractures are caused by a bone not being able to withstand increased repetitive force, improper shoe gear (severe wear), and increasing activity too rapidly. Stress fractures can account for approximately 10% of running injuries and often occur in activities that involve muscle fatigue.

Signs and Symptoms of Stress Fractures

Female athletes are more prone to stress fractures than their male counterparts due to what is commonly called the “female athlete’s triad”. This triad involves eating disorders (anorexia nervosa or bulimia), amenorrhea, and osteoporosis. Each provides increased risk to developing stress fractures due to loss of bone density and mass. As bone density and mass are affected by hormones and nutrition.

If you suspect you have a stress fracture, you will possibly experience:

1. Tenderness over the area

2. Pain upon weight bearing

3. Slight swelling and reproducible pain with activity that is relieved with rest

Diagnosis

To definitively diagnose a stress fracture, an x-ray may be taken or other advanced imaging techniques (bone scan, CT, MRI, etc) may be necessary.

Treatment of Stress Fractures

It is advised to decrease your activity, change the intensity of your activity, change your footwear, and/or you may be prescribed orthoses. It is important to rest as the fracture will need 6-8 weeks to completely heal.

Prevention

To prevent your potential for stress fractures, inspect your shoes for creases and/or wear in the midsole, replace if worn or old, and be aware of changes in your running surfaces, as one the most common areas for stress fractures are the foot, tibia, and fibula. Try to add cross training to your exercise regimen, as alternating with different stretching; strengthening and flexibility exercises can decrease your chance for stress fractures. It is important to follow the medical advice during your recovery period, so that you can get “back on the road” in a shorter period of time. As returning to “normal” activity too quickly may cause a recurrence and possibly a larger, more difficult to heal stress fracture. Be an advocate for your foot health.

Pain In The Ball Of Your Foot

Metatarsalgia is a foot condition involving pain and inflammation in the ball of the foot just behind the toes. Pain may range between sharp, aching, or burning. Other symptoms may include pain that worsens with standing, walking, foot flexing, or running and improves with rest; sharp or shooting pain, numbness, or tingling in the toes; or increased pain when walking barefoot. Some patients describe a sensation similar to walking on pebbles. The primary cause of metatarsalgia is due to excessive pressure on the metatarsals, the bones that connect to the toes. Runners and others who participate in high-impact sports are most susceptible to metatarsalgia. Certain foot structures may also make a person more vulnerable to the condition.

Correcting foot problems has greatly improved over the past few years. Today’s newer treatments and techniques include special foot care products, custom orthotics, innovative, less invasive surgeries, even joint replacement. Your feet are not supposed to hurt. When they do, we are available at SHENANDOAH PODIATRY to ease your pain and get you walking in comfort.

8 Tips For Healthy Feet on the Trail

My office is located within one mile of the Appalachian Trail. Each summer, I observe the wave of through hikers making the 2,168 mile trek from Georgia to Maine and then later in the summer, those heading south from Maine to Georgia. Many end up with a visit to my office for ankle sprains, stress fractures, infected blisters and various other hiking related conditions. Recently, I received a call from a friend that is through hiking for her second time in the past 10 years. She was in North Carolina at the time and was experiencing unrelenting pain in her foot. Having a telephone consultation and attempting to determine her diagnosis without examination was interesting and challenging. It made me think about the new trend in Internet or telephone doctor "visits". But, that is a subject for another post on another day. I want to share with you these tips to keep your feet happy on the trail:

Train For The Hike:
If you are considering a long trip such as through hiking the Appalachian Trail, I strongly suggest that you start out training early with short day hikes. Marathon runners must train and condition for a marathon and hikers are no different. Those that are not adequately conditioned are more likely to develop overuse injuries.

Pack A Foot-Care Kit:
A small foot-care kit carried in a small Ziploc bag weighs only a few ounces. It should contain foot powder, alcohol wipes, a few tinctures of benzoin wipes to help the patch stick to your skin, several blister patches of your choice, a least a yard of duct tape wrapped around a small pencil, and a safety pin to drain blisters.

Invest In Good Footwear:
You should have a fingers width between the longest toe and the front of your boot. Be sure to also check the fit on an incline (both up and down). Any slippage of the boot will cause friction and blisters on a long hike. Try your boots on with the socks that you will be wearing while hiking.

Break In Those Boots:
Wear your boots around the house for a few days to be sure they feel OK. Then venture outside while shopping and on walks and short hikes so they mold to your feet. Leather boots are usually stiff until broken in. If a little snug, you can bring your boots to a shoe repair to have them stretched or purchase a leather expander and stretch the boots at home.

Wear Good Socks:
Wear moisture-wicking wool or synthetic socks rather than cotton socks. Consider wearing a sock liner but be sure that your boots will be big enough for two pair of socks.

Manage Your Toenails:
Toenails should be trimmed straight across the nail—never rounded at the corners. Leave an extra bit of nail on the outside corner of the big toe to avoid an ingrown toenail. Black toenails are a common hikers condition which is caused by blood being trapped under the nail.

Manage Your Skin:
Treat hot spots early! Use moleskin or duct tape to prevent blisters before they happen. Many hikers think tough callused skin helps prevent blisters but too much is never a good thing. Blisters deep under calluses are difficult to drain and treat. Use a pumice stone or callus file and apply Vaseline to manage callused areas. Blasters can be drained if painful but be sure to leave the roof intact to protect the sensitive skin underneath.

Rest Your Feet:
Take your boots and socks off when resting and eating lunch, elevating your feet to reduce swelling. In camp wear sandals or flip-flops. Your feet need the air and will appreciate the sunlight.

Long distance hiking is an incredibly rewarding experience. May these tips keep your feet healthy on the trail!

Happy Trails,
Dr. Jennifer Feeny
