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.

Flatfoot is a foot disorder that is not as straightforward as many people believe.  Various types of flatfoot exist, each with their own varying deformities and symptoms.  The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot.  Other signs of flatfoot include:

• “Toe drift,” or the pointing outward of the toes and the front part of the foot
• The tilting outward of the heel and the tilting inward of the ankle
• The lifting of the heel off the ground earlier when walking due to a tight Achilles tendon
• Hammertoes
• Bunions

One of the most common types of flatfoot is flexible flatfoot.  This variation usually starts in childhood and progresses as one ages into adulthood.  Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing.  When not standing, the arch returns.  Symptoms of flexible flatfoot include:

• Pain located in the heel, arch, ankle, or along the outside of the foot
• Overpronation, or an ankle that rolls in
• Shin splint, or pain along the shin bone
• General foot aches or fatigue
• Pain located in the lower back, hip, or knee

Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit.  X-rays may be taken to define the severity and help determine the treatment option best for your condition.  Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices.  If nonsurgical methods prove ineffective, surgery may be considered.  Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.

As you grow older, you will start to notice more problems with your feet due to wear and tear. This may also happen because the skin will start to become thin and lose elasticity. Some signs of aging feet are regular aches and pains, bunion development, and clawed toes.

Fortunately, there are ways you can improve comfort, relieve pain, and maintain mobility in your feet. One of the best ways to deal with aging feet is to exercise. If you keep active, your muscles will become toned which will then strengthen the arches in the foot and stimulate blood circulation.

It is important that you practice proper foot care to protect your aging feet. You should wash your feet in warm water on an everyday basis. Afterward, the feet need to be dried well and it is important to dry between the toes. Your toenails should be trimmed and kept under control; nails that are poorly cut may become ingrown. At the end of each day, performing an inspection of your feet will allow you to detect any ailments in their early stages.

As you grow older, it becomes more important that you wear comfortable shoes. Your shoes should be secure, and they should provide decent arch support. If you are looking to buy a new pair of shoes, it is best to look for a pair that are made from a breathable material. It is also helpful to have shoes that have a bit of extra room at the top of the shoe, especially if you suffer from swollen feet.

The most common foot problems that elderly people will encounter are bunions, calluses, corns, hammertoes, heel pain, and foot problems related to diabetes. Some other issues include arch pain, tarsal tunnel syndrome, Achilles tendonitis, and Morton’s neuroma

An annual foot examination is a great way for you to ensure that you do not have any serious health problems with your feet. You should talk to a podiatrist about the available treatment options for whichever foot issue you are dealing with.

During your lifetime, you will probably walk about 75,000 miles, which is quite a lot of stress to put on your feet. As you get older, the 26 bones and 30 joints in each of your feet will lose flexibility and elasticity. Your foot’s natural shock absorbers will wear down as well. Having arthritis added to this mix only makes matters worse. Your joints will become distorted and inflamed, which is why arthritic foot care needs to be something to think about every day.

When dealing with arthritis, having additional foot complications, such as bunions, hammertoes, or neuroma, can be a serious detriment. To avoid these, buy well-fitting shoes with a lower heel and good support. Arthritis causes you to lose your arch, so having shoes with good arch support is also highly recommended.

Aside from getting good arch support, the shoes need to fit comfortably and properly as well. A good place to start is by leaving a finger width between the back of the shoe and your foot to gauge proper size. It is also helpful to have a square or rounded toe box in the front to provide even more comfort. Another thing to look for is a rubber sole that can provide a cushion and absorb shock as you walk. This adds flexibility to the ball of your foot when you push off your heel to walk.

Exercise is another key aspect of arthritic foot care. Exercise not only strengthens and stretches your muscles and joints, but helps to prevent further injury and pain as well. Stretching the Achilles tendon, the tendon located in the back of your heel, will give you added mobility and reduce pain due to stress. Another thing you can do is massage your feet, kneading the ball of your foot as well as your toes from top to bottom.

Stretching the Achilles tendon is a simple exercise that you can do at home anytime. Lean against the wall with your palms flat against the surface while placing one foot forward, towards the wall, and one foot behind you. Bend your forward knee towards the wall while keeping your back knee locked straight, and make sure both your heels are completely touching the ground at all times. This will stretch your Achilles tendon and calf muscles as well. You will feel the stretch almost immediately. You can also stretch your toes in a couple ways. One involves taking a rubber band and wrapping it around both your big toes while your heels remain together. Then, pull them apart to stretch your big toe. You can also place a rubber band around all the toes of one of your feet. Then, try to separate each individual toe, stretching them all.

A final step you can take to help your arthritis is taking non-steroid, non-inflammatory drugs or topical medicines with capsaicin. Unfortunately, there is no complete way to remove all of your arthritic pain. However, following some of this advice can go a long way in staying as pain-free as possible.
