More and more public places require people to change into slippers when entering the house, but wearing a pair of shoes with others may increase the risk of mold infection, so be careful. Pharmacist Chen Jincai pointed out that the weather in Taiwan is hot and humid, and if the hygiene habits are not good, it is easy to contract tinea pedis, which is the so-called Hong Kong athlete.

Each step you take involves a complex network of bones, muscles, tendons, and ligaments. This, combined with all of the weight they carry, explains why feet can have problems. To keep your feet healthy

• Examine your feet regularly
• Wear comfortable shoes that fit
• Wash your feet daily with soap and lukewarm water
• Trim your toenails straight across and not too short

Your foot health can be a clue to your overall health. For example, joint stiffness could mean arthritis. Tingling or numbness could be a sign of diabetes. Swelling might indicate kidney disease, heart disease, or high blood pressure.

Good foot care and regular foot checks are an important part of your health care. If you have foot problems, be sure to talk to your doctor.

Athlete's foot is a common infection caused by a fungus. It most often affects the space between the toes. Symptoms include itching, burning, and cracked, scaly skin between your toes.

You can get athlete's foot from damp surfaces, such as showers, swimming pools, and locker room floors. To prevent it

• Keep your feet clean, dry, and cool
• Wear clean socks
• Don't walk barefoot in public areas
• Wear flip-flops in locker room showers
• Keep your toenails clean and clipped short

Treatments include over-the-counter antifungal creams for most cases and prescription medicines for more serious infections. These usually clear up the infection, but it can come back.

Corns and calluses

Painful areas on the feet can be a great source of misery, making walking uncomfortable. Sufferers are often reluctant to take regular exercise.

Among the most common causes of sore feet are calluses and corns. These are raised areas of local thickening of the surface layer of the skin. This layer is known as the keratin layer. When it becomes thickened the condition is known as hyperkeratosis.

Calluses and corns are usually found in places where there is friction or pressure. They are usually the result of badly fitting shoes, but can also occur if your feet are abnormally shaped. They are sometimes found on other parts of the body where friction occurs, for example, on the fingers of guitar players.

Calluses are bigger than corns and are usually found on the bottom (sole) of the foot, either around the heel or around the front of the foot at the base of the first and fourth toes — places where pressure occurs.

Corns are smaller and often have a central core, or ‘plug’, of keratin, which can be seen. The top of the fifth toe (where it gets squashed by tight shoes) is the most common site for a corn. Sometimes they are found between the toes, where they can be extremely painful.

Treatment of corns and calluses

The best way to treat corns and calluses is to remove the hard keratin on a regular basis. This can be done by ‘shaving’ with a sharp, preferably sterile, blade. This is best done by a doctor or podiatrist. For those who prefer the do-it-yourself approach, a pumice stone can be used to do the job. Various preparations are available to help soften the areas of hyperkeratosis. These usually contain salicylic acid, which is present in corn plasters.

Although the discomfort of calluses and corns is often easily fixed, the problem will inevitably come back if the underlying problem, usually wearing the wrong pair of shoes, is not corrected. If changing shoes does not help, seeing a podiatrist may be helpful.

Diabetic conditions affecting the legs and feet

The feet and legs are common sites for complications in people with diabetes mellitus and for this reason good foot care is very important. An injury to the foot or leg can be painful, but in people suffering from diabetic neuropathy (nerve damage) the sensations are dulled and minor injuries often go undetected and untreated, potentially leading to more serious damage.

Loss of temperature sensation is also a significant risk factor for injury in people with diabetes. This can result in a person being unaware that the bath water they are stepping into is scalding them. They may also be at risk of developing severe burns after sitting too close to a heater.

Special attention is needed to prevent circulatory disorders and infections that commonly occur in the lower extremities of people with diabetes. Areas with poor circulation heal badly and, if left unattended, such injuries may develop into ulcers or even become gangrenous.

Do not ignore pain in the feet or legs as this may indicate a problem. Corn plasters should not be used as they may cause foot ulcers.

Good foot care

Good foot care is vitally important for people with diabetes. Every day, wash your feet in warm (not hot) water. If you notice a callus forming, you can try to gently remove it (for example, with a pumice stone). However, once formed, calluses should only be treated by professionals. After washing, apply a moisturiser to your feet, but avoid moisturising between your toes. When you cut your toenails, cut straight across and file down any sharp edges.

Always wear shoes and socks, and choose your shoes carefully. Shoes should be large enough to be comfortable, but not large enough to be slipping off. They should have resilient (but not soft) insoles, and be smooth on the inside, with no rough areas.

Check your feet each night, looking for:

• dry, scaly, red, itching or cracked skin;

• areas where something has been rubbing on your feet;

• blisters;

• cuts or abrasions;

• corns or calluses;

• infections;

• thickened or discoloured nails;

• blueness or any swelling; and

• any red, hot or swollen areas.

If your vision is poor, get someone to check for you.

Any breaks in the skin need to be treated straight away, so see your doctor or podiatrist. Also, try to work out what might have caused the problem so that you can prevent it happening again. If one of your feet is hot and swollen, check it again the next day — see your doctor if it remains hot and swollen.

Your feet should also be examined regularly by a doctor, diabetes specialist or podiatrist. Your doctor or podiatrist can advise you on foot care and also on the selection of appropriate footwear.

Here is a list of quick questions to help you check the health of your feet.

1. Do you have pain in your feet?
2. Are you on your feet all day?
3. Do you have skin or nail problems (ingrown or discoloured toenails, corns, skin rashes, areas of hard skin) on your feet?
4. Do you have any sores on your feet that are not healing?
5. Do you have foot odour?
6. Do you have a foot injury?
7. Do you have health problems such as diabetes or arthritis?
8. Do you have numbness, tingling or burning in your feet?
9. Do your feet have poor circulation - are they unusually pale, blue or red?
10. Do you trip or fall often?
11. Do you have problems finding shoes that fit comfortably?
12. Do you have lumps or bumps, bunions or misshapen toes?
13. Do you regularly wear heels that are 5 cm (2 inches) or higher?
14. If you have answered ‘yes’ to any of these questions, see a podiatrist or your doctor for diagnosis and treatment.

Foot problems include athlete’s foot, plantar warts (verrucae), corns, smelly feet and infected toenails.

• Athlete’s foot is a fungal infection — also called tinea pedis. It is contagious via direct contact, wet floors and shared footwear.
• Plantar warts (verrucae) are flat warts in the sole of the foot. They are forced under the skin and may occur in clusters. The surface is greyish and crumbly, and they may contain small black points that are swollen blood vessels. Plantar warts are also contagious via wet floors. Like other warts, they will disappear on their own, but this may take up to 2 years.
• Corns are areas of hard skin that build up on parts of the foot that are subject to pressure or friction, such as on the little toe.
• Smelly feet are usually caused by excessive perspiration and an over-growth of fungi and/or bacteria.
• Infected toenails are commonly the result of a fungal infection, a condition known as onychomycosis. Toenails affected by onychomycosis are often brittle, discoloured or yellow.

What can you do to care for your feet?

Here are several steps you can take towards healthy feet.

• Wear thongs in public showers such as in camping grounds and gyms to help prevent you from contracting athlete’s foot.
• Wash your feet twice daily and dry them thoroughly, particularly between your toes. Use a clean towel.
• Change your socks daily and wear cotton, not synthetic, socks.
• Wash your socks and towels at a high temperature (hot cycle on washing machine).
• Wear well-fitting leather shoes that allow your feet to ‘breathe’ (synthetic shoes tend to increase the amount of perspiration) or wear open shoes or sandals to allow air to circulate freely.
• Bleach your shower/bath area.
• When applying corn or wart medication, make sure it does not get on the healthy, unaffected skin.

When should you seek medical advice?

All of the above conditions can be treated: some by medications that are available from pharmacists, while others, particularly fungal nail infections, can require prescription medication from your doctor. You should also seek medical advice if:

• you suffer from diabetes, as you may lack some feeling in your feet and that can lead to complications such as ulcers;
• you are elderly, as you may have poor circulation;
• you have a mole or dark-coloured spot on your foot; 
• there is bleeding.

Diabetes can damage the nerves and blood vessels in your feet. This damage can cause numbness and reduce feeling in your feet. As a result, your feet may not heal well if they are injured. If you get a blister, you may not notice, and it may get worse.Check your feet every day. Inspect the top, sides, soles, heels, and between the toes. Look for:

• Dry and cracked skin
• Blisters or sores
• Bruises or cuts
• Redness, warmth, or tenderness
• Firm or hard spots

If you cannot see well, ask someone else to check your feet.Call your doctor right way about any foot problems. Do not try to treat them yourself first. Even small sores or blisters can become big problems if infection develops or they do not heal.Wash your feet every day with lukewarm water and mild soap. Strong soaps may damage the skin.

• Check the temperature of the water with your hands or elbow first.
• Gently dry your feet, especially between the toes.
• Use lotion, petroleum jelly, lanolin, or oil on dry skin. Do NOT put lotion between your toes.

Ask your health care provider to show you how to trim your toenails.

• Soak your feet in lukewarm water to soften the nail before trimming.
• Cut the nail straight across, because curved nails are more likely to become ingrown.
• Your foot doctor (podiatrist) can trim your nails if you are unable to.

Most people with diabetes should have corns or calluses treated by a foot doctor. If your doctor has given you permission to treat corns or calluses on your own:

• Gently use a pumice stone to remove corns and calluses after a shower or bath, when your skin is soft.
• Do NOT use medicated pads or try to shave or cut them away at home.

If you smoke, stop. Smoking decreases blood flow to your feet. Talk with your doctor or nurse if you need help quitting.Do not use a heating pad or hot water bottle on your feet. Do not walk barefoot, especially on hot pavement or hot sandy beaches. Remove your shoes and socks during visits to your health care provider so that they can check your feet.

Shoes and Socks

Wear shoes at all times to protect your feet from injury. Before you put them on, always check the inside of your shoes for stones, nails, or rough areas that may hurt your feet.

Wear shoes that are comfortable and fit well when you buy them. Never buy shoes that are tight, hoping they will stretch as you wear them. You may not feel pressure from shoes that do not fit well. Blisters and sores can develop when your foot presses against your shoe.

Ask your doctor about special shoes that can give your feet more room. When you get new shoes, break them in slowly. Wear them 1 or 2 hours a day for the first 1 or 2 weeks.

Change your broken-in shoes after 5 hours during the day to change the pressure points on your feet. Do not wear flip-flop sandals or stockings with seams. Both can cause pressure points.

Wear clean, dry socks or non-binding panty hose every day. They will help protect your feet. Holes in socks or stockings can put damaging pressure on your toes.

You may want special socks with extra padding. Socks that move moisture away from your feet will keep your feet drier. In cold weather, wear warm socks, and do not stay out in the cold for very long. Wear clean, dry socks to bed if your feet are cold.

You have had a foot amputation. You may have had an accident, or your foot may have had an infection or disease and doctors could not save it.

What to Expect at Home

It will take time for you to learn to use a walker and a wheelchair. It will also take time to learn to get in and out of the wheelchair. You may also be getting a prosthesis, a manmade part to replace your limb that was removed. You will have to wait for the prosthesis to be made. When you have it, getting used to it will take time.

You will probably have pain in your limb for several days after your surgery. You may also have a feeling that your limb is still there. This is called phantom sensation. 

You may feel sad, angry, frustrated, or depressed. All of these feelings are normal. You may have them when you were in the hospital or when you get home.

Self-care

Family and friends can help. Talking with them about your feelings may make you feel better. They can also help you do things around your house and when you go out.

If you feel sad or depressed, ask your doctor about seeing a mental health counselor for help with your feelings about your amputation.

If you have diabetes, keep your blood sugar under control. 

If you have poor blood flow to your foot, follow your doctor's instructions for diet and medicines.

You may eat your normal foods when you get home.

Wound and Foot Care

Do NOT use your limb until your doctor tells you it is okay to use it again. This will be at least 2 weeks or longer after your surgery. Do not put any weight at all on your wound. Do not even touch it to the ground, unless your doctor says so. Do NOT drive.

Keep the wound clean and dry. Do not take a bath, soak your wound, or swim. If your doctor says you can, clean the wound gently with mild soap. Do not rub the wound, but allow water to flow gently over it.

After your wound heals, keep it open to the air unless your doctor or nurse tells you something different. After dressings have been removed, wash your stump with mild soap and water every day. Do not soak it. Dry it well. 

Inspect your limb every day. Use a mirror if it is hard for you to see all around it. Look for any red areas or dirt.

Wear your elastic bandage or shrinker sock on the stump all the time. If you are using an elastic bandage, rewrap it every 2 to 4 hours. Make sure there are no creases in it. Wear your stump protector whenever you are out of bed.

Ask your doctor or nurse for help with pain. Two things that may help are:

• Tapping along the scar and in small circles along the stump, if it is not painful

• Rubbing the scar and stump gently with linen or soft cotton

Practice transfers at home:

• Go from your bed to a chair, your wheelchair, or the toilet.

• Go from a chair to your wheelchair.

• Go from your wheelchair to the toilet.

If you use a walker, stay as active as you can with it.

Keep your stump at or above the level of your heart when you are lying down. When you are sitting, do not cross your legs. It can stop the blood flow supply to your stump.

When to Call the Doctor

Call your doctor if:

• Your stump looks redder, or there are red streaks on your skin going up your leg.

• Your skin feels warmer to touch.

• There is swelling or bulging around the wound.

• There is new drainage or bleeding from the wound.

• There are new openings in the wound, and the skin around the wound is pulling away.

• Your temperature is above 101.5° F more than once.

• Your skin around the stump or wound is dark or is turning black.

• Your pain is worse, and your pain medicines are not controlling it.

• Your wound has gotten larger.

• A foul smell coming from the wound.

One perk of a beach-bound vacation is knowing that instead of snow soaking through your Choos or having your feet feeling toasty in sweaty Uggs, you can lounge happily with your toes dangling in the warm weather, shoe-free with the sand at your feet. But alas, the dream does come with its own set of tootsie troubles. "Even if you are just lying still on your back soaking up the rays, your feet are still vulnerable," says American Podiatric Medical Association member Dr. Jane Andersen. "You can seriously sunburn your feet and no matter how upscale your hotel, athlete's foot can lurk in all public pool areas."

Wouldn't you rather spend time collecting sea shells than doctor's bills? No worries. There are ways to prevent these future foot predicaments so you can go back to your sun-kissed dreams and enjoy a liberated foot experience.

1. Limit walking barefoot as it exposes feet to sunburn, as well as plantar warts, athlete's foot, ringworm, and other infections and also increases risk of injury to your feet.
2. Wear shoes or flip-flops around the pool, to the beach, in the locker room and even on the carpeting or in the bathroom of your hotel room to prevent injuries and limit the likelihood of contracting any bacterial infections.
3. Remember to apply sunscreen all over your feet, especially the tops and fronts of ankles, and don't forget to reapply after you've been in the water.
4. Stay hydrated by drinking plenty of water throughout the day. This will not only help with overall health, but will also minimize any foot swelling caused by the heat.
5. Keep blood flowing with periodic ankle flexes, toe wiggles, and calf stretches.
6. Some activities at the beach, lake or river may require different types of footwear to be worn so be sure to ask the contact at each activity if specific shoes are needed. To be safe, always pack an extra pair of sneakers or protective water shoes. If your shoes will be getting wet, they should be dried out completely before your next wearing to prevent bacteria or fungus from growing.
7. If you injure your foot or ankle while on vacation, seek professional medical attention from a podiatric physician. Many often only contact a doctor when something is broken or sprained, but a podiatrist can begin treating your ailment immediately while you're away from home.
