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.
Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters. Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.
Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.
Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.
To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.
Cuboid Syndrome
Cuboid syndrome mostly affects athletes, although it can affect non-athletes too. It is also known as cuboid subluxation or cuboid fault syndrome. This condition occurs when joints and ligaments near the cuboid bone of the foot are damaged, or when the cuboid bone itself is dislodged from its natural position. It is usually marked by pain on the outer side of the foot, which may be persistent or may come and go. Cuboid syndrome can be difficult to diagnose unless it becomes severe and more noticeable. Your doctor will likely ask questions about when the pain began and how long it has been present, and will put pressure on the cuboid bone to determine if that area is the origin of the pain.
Causes of Cuboid Syndrome
- Any repetitive stresses placed on the foot due to athletic activities are a common cause of cuboid syndrome.
- Although it develops over time, it is possible that this syndrome can occur all of sudden due to a single event or injury.
- Over-pronation can exacerbate the condition if not corrected.
Disagreements Amongst Podiatrists Regarding Cuboid Syndrome
- Some refer to it as the dislocation of the calcaneal-cuboid joint only.
- Other podiatrists see it as an injury of the ligaments located nearby, which also involves the cuboid bone.
It is very important that when you experience any kind of pain on the side of your foot, you should seek medical care right away. If a subluxed cuboid is caught early, your feet may respond well to the treatment, and you can get back into sports or other activities again as soon as the pain subsides.
The natural weight that pregnant women gain causes their center of gravity to be completely altered. This causes them to have a new weight-bearing stance which adds pressure to the knees and feet. As a result, pregnant women often experience severe foot pain. The two most common foot issues experienced by women in their pregnancies are edema and over-pronation. It is important for all pregnant women to learn more about how to take care of their feet so they are more comfortable during their pregnancy.
Over-pronation, which is commonly referred to as flat feet, is caused when a person’s arch flattens out upon weight bearing. This causes the person’s feet to roll inward while walking. Pregnant women often experience this due to the sudden weight they gain.
Edema, also referred as swelling in the feet, typically occurs in the later part of the pregnancy. It is the result of the extra blood accumulated in the pregnant woman’s body. The enlarged uterus puts more pressure on the blood vessels in the pelvis which causes leg circulation to slow down. This causes blood to pool in the lower extremities.
Fortunately, there are ways to treat both edema and over-pronation. Edema can be treated by elevating the foot as often as possible. Wearing proper fitting footwear will also be helpful for those with edema. A treatment method for over-pronation could be orthotics. Orthotic inserts should be designed with appropriate arch support and medial rear foot for your foot.
It is best for pregnant women to buy new shoes during the day, because this is the time where swelling is at its peak. Pregnant women also shouldn’t rush when buying shoes. It is always advised that you make sure your shoes fit properly but this is especially important during pregnancy.
If you are a pregnant woman, you should consult with a podiatrist in order to make sure your feet are healthy throughout the entirety of your pregnancy.
