Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.

Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound.  To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.

To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.

A corn is a lesion that forms in the skin of the foot, and it is typically circular in shape, small in size, and thick and rough in texture.  A corn generally occurs as a result of repeated pressure on the skin; one example of this is the rubbing of a shoe against the skin.  Corns differ from calluses in that their central cores are harder in texture.

A corn is a relatively common condition with a wide variety of treatment options.  If a corn becomes overly uncomfortable or painful, consult with your podiatrist; he can determine the best method of treatment that is appropriate for you.  Corns may return if the underlying cause of its development is not treated or removed.  Avoid removing corns at home, as improper removal may cause infection.

A callus, similar to a corn, is an area of skin that has become thickened due to repeated pressure and rubbing.  The rubbing causes the skin to create a layer of protective skin, which is the formed callus.  Calluses can differ in size between people, and they can also become painful.

Multiple treatments are available for calluses.  At-home treatment and removal should be avoided, as this can potentially lead to infection.  Your podiatrist can best determine the cause of your calluses and suggest the treatment most appropriate for you. 

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.

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.
