Blisters are a common ailment of people who wear shoes that are either too tight or rub against the feet in an uncomfortable way. Knowing the basics of blisters is important for understanding how they are formed and what treatments should be used for them.

A blister on the foot, or any other part of the body, is a small pocket that is filled with fluid. It usually forms on the upper layer of the skin because these layers are loose enough to allow a blister to form. The most common fluid in a blister is just a clear, watery-like fluid that usually isn’t cause for concern. However, blisters can fill up with blood if they are deep enough and pus if they have become infected with bacteria.

Blisters almost always form on the feet due to shoes rubbing up against the foot, where the friction causes blisters. These can occur after you have walked for a long period of time or when your shoes do not fit you properly. Your feet are also more prone to blisters if they are moist, so keeping them dry and clean is one preventative step you can take.

Preventing infection should be the number one concern when treating blisters, as well as relieving the pain they can cause. Using a bandage to cover up the blister will help it heal and prevent bacteria from entering it. New skin will form under the blister and eventually cause it to pop. You can also take a sterilized pin and try to pop it yourself.

If the blister is filled with pus or blood, seeking treatment from a doctor is ideal. Antibiotics may need to be taken in order to completely eliminate the bacteria inside the blister. See a doctor to have an antibiotic prescribed.

The best way to treat blisters is to prevent them all together. Keeping your feet dry and making sure that your shoes fit properly are just two of the steps you can take to prevent blisters. Shoes that are too tight or shoes that are too loose and allow your feet to slide in them will cause blisters. Applying a bandage to an area where you think a blister is about to form is another way you can prevent them.

Each foot, on average, has about 250,000 eccrine sweat glands that produce half a pint of sweat each day. Sweating is a natural and important bodily function. It regulates the body’s temperature by cooling the skin so that it does not overheat.  In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than what is required. People with plantar hyperhidrosis experience an excess amount of sweat on their feet. It is estimated that 2% to 3% of all Americans suffer from some form of hyperhidrosis. This condition is often caused by neurologic, endocrine, infectious, and other systemic disease. Other factors that may trigger the condition are heat and emotions.

People with hyperhidrosis may notice an overabundance of sweat on their feet, along with a strong odor. The feet may also have a wet appearance coupled with infections such as athlete’s foot or toenail fungus. The sweat may even appear in low temperatures, such as during the winter months. People with plantar hyperhidrosis often need to change their socks several times throughout the day.

The specific cause of hyperhidrosis is unknown, and many believe it may be caused by over-activity. However, others believe the condition is genetic.  Caffeine and nicotine are known to cause excitement and nervousness which are two emotions that may make the condition worse.

If you are looking to treat your hyperhidrosis the most important thing you should do is wash your feet every day.  You may even need to wash your feet twice a day, if necessary.  You should also make sure you are wearing the right socks. Wool and cotton socks are both known to be good for ventilation, meaning they allow the feet to breathe. You should avoid socks made from nylon which trap moisture and lead to sogginess. Other common treatment options are over-the-counter antiperspirants that contain a low dose of metal salt.  In some cases, prescription strength antiperspirants that contain aluminum chloride hexahydrate may be necessary. In severe cases, surgery may be required.

Untreated hyperhidrosis can easily lead to complications.  Some complications that may arise from the disorder include nail infections, warts, and bacterial infections.  Consequently, it is important that you seek treatment from your podiatrist if you suspect that you may have plantar hyperhidrosis.

A bunion is a bump that forms at the base of the big toe. Bunions form when the big toe pushes against the next toe, which forces the big toe joint to get bigger and stick out.  As a result, the skin over the bunion may start to appear red and it may feel sore.

There are risk factors that can increase your chances of developing bunions. People who wear high heels or ill-fitting shoes are more likely to develop them, in addition to those who have a genetic history of bunions or have rheumatoid arthritis.

The most obvious way to tell if you have a bunion is to look for the big toe pushing up against the toe next to it. Bunions produce a large protrusion at the base of the big toe and may or may not cause pain. Other symptoms are redness, swelling, and restricted movement of the big toe if you have arthritis. 

Nonsurgical methods are frequently used to treat bunions that aren’t severe. Some methods of nonsurgical treatment are orthotics, icing and resting the foot, taping the foot, and pain medication. Surgery is usually only required in extreme cases. However, if surgery is needed, some procedures may involve removing the swollen tissue from around the big toe joint, straightening the big toe by removing part of the bone, or joining the bones of your affected joint permanently.

Your podiatrist will diagnose your bunion by doing a thorough examination of your foot. He or she may also conduct an x-ray to determine the cause of the bunion and its severity.

Many pregnant women complain about foot pain while they are expecting. Foot pain can primarily be caused by weight gain and hormonal changes taking place in the body. By understanding how pregnancy impacts the health of a woman's feet, a pregnant woman can take action to keep her feet as healthy and comfortable as possible.

Because a woman's weight changes during pregnancy, more pressure is brought to bear on both the legs and the feet. This weight shift can cause two major foot problems: over-pronation, also known as flat feet, as well as edema, which is swelling of the feet. Over-pronation occurs when the arch of the foot flattens, causing the foot to roll inwards when the individual is walking, and can aggravate the plantar fascia tissues located along the bottom of the feet. If these tissues become inflamed, a pregnant woman can experience pain in the heel of the foot as well as severe foot pain while walking or standing. Swelling of the feet, or edema, often occurs in the later stages of pregnancy. It is caused by slow circulation and water retention, and may turn the feet a light purple color.

To keep feet in good health and prevent over-pronation, pregnant women should avoid walking barefoot and be sure they are wearing shoes that offer good arch support. A device known as an orthotic can be added to regular footwear in order to provide additional support for the feet during pregnancy. Any expectant mother whose feet hurt should first check to see if the shoes she is wearing are old, worn out and not offering the proper support necessary for distributing the weight of her body during pregnancy.

To treat edema of the feet, a good start is to wear quality footwear which offers support and good circulation. Keep feet elevated whenever possible by using a foot stool while seated. Stay well hydrated by drinking plenty of water to prevent water retention in the feet. Any swelling that occurs in only one foot should be examined as soon as possible by a doctor.

Good foot health during pregnancy can help expectant mothers avoid foot pain that leads to other health problems. Massaging the feet and doing regular gentle exercise like walking aids foot health by contributing to good circulation. Supportive shoes are also a good investment that will support foot health during pregnancy.
