Hyperhidrosis of the feet, also termed plantar hyperhidrosis, is characterized by excessive sweating of the feet that can be onset by any cause, such as exercise, fever, or anxiety. Most people suffering from hyperhidrosis of the feet also experience hyperhidrosis of the hands, or palmar hyperhidrosis. Approximately 1-2% of Americans suffer from this disorder.
Sweating is a healthy process utilized by the body in order to cool itself and maintain a proper internal temperature, which is controlled by the sympathetic nervous system. In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than is actually needed.
Plantar hyperhidrosis is considered primary hyperhidrosis. Secondary hyperhidrosis refers to excessive sweating that occurs in an area other than the feet, hands, or armpits, and this indicates that is related to another medical condition, such as menopause, hyperthyroidism, or Parkinson's disease.
Symptoms of hyperhidrosis of the feet can include foot odor, athlete's foot, infections, and blisters. Because of the continual moisture, shoes and socks can rot which creates an additional foul odor and can ruin the material, requiring shoes and socks to be replaced frequently. In addition to the physical symptoms, emotional health is often affected as this disorder can be very embarrassing.
If left untreated, hyperhidrosis will usually persist throughout an individual's life. However, there are several treatment options available. A common first approach to treating hyperhidrosis of the feet is a topical ointment. Aluminum chloride, an ingredient found in antiperspirants, can be effective at treating hyperhidrosis if used in high concentration and applied to the foot daily. Some individuals can experience relief this way, while others encounter extreme irritation and are unable to use the product. Another procedure is the use of Botulinum Toxin A, commonly referred to as Botox. This is injected directly into the foot, and is effective at minimizing the sweat glands in the injected area. These injections must be repeated every 4 to 9 months.
If these treatments are ineffective, oral prescription medications may be taken in an effort to alleviate the symptoms. Again, some will experience relief while others do not. Going barefoot reportedly provides relief for most sufferers.
A final approach to combating hyperhidrosis of the feet is through surgery. Surgery has been less successful on patients with plantar hyperhidrosis than on those with palmar hyperhidrosis. It is only recommended when sweating is severe and other treatments have failed to work. This kind of surgery usually involves going into the central nervous system, and cutting nerves to stop the transmission of signals telling the foot to sweat.
According to the American Diabetes Association (ADA), diabetes is a condition that affects approximately 23.6 million Americans. Around 750,000 new cases are diagnosed each year, and the disease’s most common form, Type 2 diabetes, makes up for 90 to 95 percent of these cases. Type 2 diabetes is especially prevalent among older Americans, those who are obese, and those who lead sedentary lifestyles.
Complications of the disease may lead to several foot and ankle-related conditions. The loss of nerve sensation, or neuropathy, can cause diabetics to lose feeling at the bottom of the feet and therefore leave them unaware of pain, pressure, and heat. Decreased circulation is another complication of diabetes that can slow down the healing of wounds and injuries; this can lead to the development of foot ulcers.
To prevent foot ulcers from forming, diabetics should examine their feet every day for small cuts and wear shoes that curtail pressure. Constant monitoring for the risk factors associated with ulcer formation can allow for early detection and therefore lessen the possibility of ulcers or, even worse, amputation. The removal of calluses and ingrown toenails should be left to the podiatrist to avoid improper removal and possible infection.
Diabetic patients may also experience foot deformities due to complications in their feet, such as limited joint mobility, muscle atrophy, and decreased fat padding. These complications can increase pressure in certain areas of the foot, which in turn can cause certain deformities, such as hammertoe, to form. Another deformity, Charcot foot, develops due to the collapsing of microfractures in the bones of the feet. The resulting deformity is a foot that is flattened and wider in appearance.
To help minimize pressure and prevent the development of these diabetes-related foot and ankle conditions, your podiatrist may consider using orthotics or special shoes. Charcot foot may be treated using walkers, custom orthotic insoles, or non-weight-bearing or rigid weight-bearing casts or braces. In more serious cases, surgery may be considered to treat more developed deformities. Ulcers can be further cared for with the help of proper diet, medication to control glucose, intensive wound care, and infection treatment.
An ingrown toenail is a nail that has curved downward and grows into the skin. This typically occurs at the nail borders, or the sides of the nail. As a result, pain, redness, swelling, and warmth may occur in the toe. If a break in the skin forms due to the ingrown nail, bacteria may enter and cause an infection in the area; this is typically characterized by a foul odor and drainage.
Ingrown toenails have multiple reasons for developing. In many instances, the condition is a result of genetics and is inherited. The most common cause, however, is improper trimming; cutting the toenails too short forces the skin beside the nail to fold over. An ingrown toenail can also develop due to trauma, such as stubbing the toe, having an object fall on the toe, or participating in activities that involve repeated kicking or running. Wearing shoes that are too tight or too short can also cause ingrown toenails.
Treatment for an ingrown toenail varies between patients and the severity of the condition. Milder cases that don’t involve infection or other medical conditions can benefit from soaking the feet in room-temperature water and gently massaging the side of the nail. In most cases, however, it is best to see your podiatrist for thorough and proper treatment. After examining your toe, your podiatrist may prescribe oral antibiotics to clear the infection if one is present. Surgical removal of either a portion of the nail or the entire nail may also be considered. In some cases, complete removal or destruction of the nail root may be required. Most patients who undergo nail surgery experience minimal pain afterward and can return to normal activity the following day.
Ingrown toenails can be prevented with proper nail trimming and by avoiding improper-fitting shoes. When cutting the toenails, be sure that you are cutting in a straight line and avoid cutting them too short. Shoes should not be too short or tight in the toe box.
Foot Therapy for Sports Injuries
Athletes are used to engaging in high-intensity workouts. Consequently, athletes are at an increased risk for enduring foot or ankle injuries. The most common way to treat these types of injuries is the RICE method (Rest, Ice, Compression, and Elevation). However, braces and casts may be required in some cases. If you are suffering from any of these injuries, it is best that you seek help from your podiatrist right away.
Achilles tendinitis is a type of overuse injury of the Achilles tendon, which is the tendon connecting the calf muscles to the heel. This type of injury commonly occurs in runners who increase the intensity of their workouts. Symptoms for this condition start off as a mild ache in the back leg or above the heel. Some people experience tenderness around the area in the morning, however this feeling tends to improve over time. If you suspect you have Achilles tendinitis, you doctor may order an x-ray to show whether your Achilles tendon has calcified. Common treatment options for this condition include rest, ice, exercise, and non-steroidal anti-inflammatory medication.
Plantar Fasciitis is a condition that is commonly found in women. It is a painful condition that occurs when the bands of tissue that connect the heel to the toes become inflamed. Symptoms for plantar fasciitis are heel pain that worsens in the morning and improves throughout the day with activity. Your podiatrist will diagnose plantar fasciitis by checking for tender areas on your foot. In rare cases, an x-ray may be required for a more thorough examination. There are various treatment options that may be used to help someone with this ailment. Depending on the specific case, some of these options include: physical therapy, shockwave therapy, and in rare cases, surgery.
Stress fractures are tiny cracks in the bone that occur due to repetitive force. These fractures are typically the result of overuse injuries such as repeatedly running and jumping. Symptoms of a stress fracture include pain when exercising, tenderness, and mild swelling. To diagnose a stress fracture, your doctor will likely ask you a series of questions about your overall health and the activities you are involved in. Next, an x-ray will likely be performed to check for the fracture. In some cases, fractures don’t appear on x-rays until weeks afterward. In these cases, an MRI or a bone scan may be required. Typical stress fractures may be treated by resting the area and taking a break from highly intense activities.
Ankle sprains occur when the ligaments that support the ankle are stretched far beyond their limits. These injuries occur when you roll, twist, or turn your ankle in an awkward way. Ligaments are essential in helping us move around because they are responsible for stabilizing the joints. Usually, sprained ankles occur due to ligaments on the outer part of the ankle becoming stretched. Symptoms of ankle sprains are swelling, bruising, instability of the ankle, and restricted range of motion. Normally, when people sprain their ankle, they will hear a popping sound during the injury. Depending on the severity, ankle sprains are graded based on how much damage has occurred to the ligaments. Grade 1 is mild, grade 2 is moderate, and grade 3 is severe.
