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.

Flatfoot is a condition that occurs when the arches on the foot are flattened, which allows the soles of the feet to touch the floor. Flatfoot is a common condition and it is usually painless.

Throughout childhood, most people begin to develop arches in their feet, however, some do not. Those who do not develop arches are left with flatfoot. The pain associated with flat feet is usually at its worse when engaging in activity. Another symptom that may occur with those who have this condition is swelling along the inside of the ankle.

It is also possible to have flexible flatfoot. Flexible flatfoot occurs when the arch is visible while sitting or standing on the tiptoes, but it disappears when standing. People who have flexible flatfoot are often children and most outgrow it without any problems.

There are some risk factors that may make you more likely to develop flatfoot. Those who have diabetes and rheumatoid arthritis have an increased risk of flatfoot development. Other factors include aging and obesity.

Diagnosis for flat feet is usually done by a series of tests by your podiatrist. Your podiatrist will typically try an x-ray, CT scan, ultrasound, or MRI on the feet. Treatment is usually not necessary for flat foot unless it causes pain. However, therapy is often used for those who experience pain in their flat feet. Some other suggested treatment options are arch supports, stretching exercises, and supportive shoes. 

Sesamoiditis is a condition in which the sesamoid bones in the forefoot become inflamed from physical activity. Sesamoid bones are bones that are not connected to other bones but are located in tendons or muscle. Two of these sesamoid bones are very small and located on the underside of the foot near the big toe. Athletes such as runners, baseball and football players, and dancers are likely to experience sesamoiditis. Those with high arched feet, flat feet, or runners who run on the ball of their foot are also prone to suffer from sesamoiditis.

Symptoms include pain or throbbing on the ball of the foot near the big toe. The pain generally starts with a mild throbbing but gradually builds up to shooting pain. Bruising, swelling, and redness are possible, but in most cases, these symptoms are not present. However, moving the big toe can result in pain and difficulty.

To conduct a diagnosis, the podiatrist will examine the ball of the foot and big toe. They will look for any outliers and check the movement of the toe. X-rays will be taken to rule out any other conditions and ensure that it is sesamoiditis.

Treatment for sesamoiditis is generally mild and includes rest, anti-inflammatory and pain medication, and ice treatments to deal with the swelling and pain. Orthotics may be needed with people who have flat or high arched feet to relieve pressure off the bones. In some cases the toe will be taped and immobilized to allow healing. The podiatrist may also decide to use a steroid injection to help with swelling as well. If you have sesamoiditis, you shouldn’t engage in any intensive activity, as it may inflame the area and worsen your pain. If the sesamoid bone has fractured, surgery may be required to remove the sesamoid bone.

If you are suffering from sesamoiditis or are experiencing symptoms similar to sesamoiditis, you should stop all physical activity that puts strain on the area. Furthermore you should see a podiatrist for a diagnosis to see if you have sesamoiditis.

Diabetes can cause two problems that can potentially affect the feet: Diabetic neuropathy and Peripheral Vascular Disease. Diabetic neuropathy occurs when nerves in your legs and feet become damaged, which prevents you from feeling heat, cold, or pain. The problem with diabetic neuropathy is that a cut or sore on the foot may go unnoticed and the cut may eventually become infected. This condition is also a main cause of foot ulcers. Additionally, Peripheral vascular disease also affects blood flow in the body. Poor blood flow will cause sores and cuts to take longer to heal. Infections that don’t heal do to poor blood flow can potentially cause ulcers or gangrene.

There are certain foot problems that are more commonly found in people with diabetes such as Athlete’s foot, calluses, corns, blisters, bunions, foot ulcers, ingrown toenails, and plantar warts. These conditions can lead to infection and serious complications such as amputation. Fortunately, proper foot care can help prevent these foot problems before they progress into more serious complications.       

Each day you should wash your feet in warm water with a mild soap. When you finish washing your feet, dry them carefully especially between your toes. You should also perform daily foot inspections to ensure you don’t have any redness, blisters, or calluses. Furthermore, if you are diabetic, you should always wear closed-toed shoes or slippers to protect your feet. Practicing these tips will help ensure that your feet are kept healthy and away from infection.

If you have diabetes, contact your podiatrist if you have any of the following symptoms on your feet: changes in skin color, corns or calluses, open sores that are slow to heal, unusual and persistent odor, or changes in skin temperature. Your podiatrist will do a thorough examination of your feet to help treat these problematic conditions.
