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.

A podiatrist is a Doctor of Podiatric Medicine who treats the foot, ankle, and related structures of the leg. If you are having any pain, injuries, or abnormalities in these areas, it is best that you seek help from a podiatrist.

Podiatrists complete four years of training in a podiatric medical school. Their training is like that of other physicians, and they may go on to complete a fellowship training after a residency training. Some podiatrists are board certified meaning they have advanced training, clinical experience, and have taken an exam to prove their skills. Certifying boards for podiatry are the American Board of Foot and Ankle Surgery and the American Board of Podiatric Medicine. Podiatrists may work in private practices, hospitals, clinics, or they may even become professors at colleges of podiatric medicine.

While in college, those who want to be podiatrists often take biology, chemistry, and physics classes in preparation for podiatry school. In podiatry school, students study how the bones, nerves, and muscles work together to help you move around. Additionally, they study injuries and how to properly diagnose and treat them. Admittance into podiatric medical school requires the completion of 90 semester hours of undergraduate study with a good grade point average, and acceptable scores on the MCAT (Medical College Admission Test)

Podiatrists treat many different conditions such as: aching feet, ankle pain, bunions, corns, hammertoes, fungus, ingrown toenails, plantar fasciitis, sprains and more. Common forms of treatment for these conditions are physical therapy, drugs, or surgery. Podiatrists may also recommend corrective shoe inserts, custom-made shoes, plaster casts, and strappings to correct deformities.

Even if you are someone whose feet are in generally good condition, you should still visit a podiatrist to have your feet properly exfoliated and maintained, or to make sure you are looking after your feet properly.

Foot and ankle injuries are common among athletes and those who exercise frequently. Most of these injuries are non-life-threatening and can heal in weeks with proper treatment and care. Serious injuries, however, require urgent medical treatment.

Common minor injuries include ankle sprains, ankle strains, Achilles tendonitis, plantar fasciitis, stress fractures, and turf toe. An ankle sprain is when the ligaments in the ankle have either become stretched or torn. When the muscle or tendon is stretched or torn, it is an ankle strain. When the big toe is sprained, it is known as turf toe. Achilles tendonitis is the overuse and inflammation of the Achilles tendon. Plantar fasciitis is the inflammation of the plantar fascia and generally occurs from overuse in athletics. Stress fractures are also caused from overuse and are small cracks in the bone.

Achilles tendon ruptures are common, but more serious. This injury occurs when the Achilles tendon, the largest tendon in the body, ruptures. In most cases, this causes severe pain and difficulty walking; some who have experienced this injury have reported, however, no signs or symptoms. A laceration is a deep cut that can occur anywhere on the body. Lacerations on the foot are rarer, but can occur from things like metal cleats landing on the foot.   

Treatment options cover a wide range of methods based upon the injury and its severity. Conditions like plantar fasciitis, stress fractures, Achilles tendonitis, turf toe and ankle sprains/ strains can heal on their own without immediate medical care, but seeing a podiatrist to monitor the injury is always recommended. Following the RICE (Rest, Icing, Compression, and Elevation) protocol is generally enough to treat minor injuries. This means resting the foot by either keeping pressure off the foot or not walking at all. Icing the injury will help reduce swelling and pain. Compressing the wound with a wrap will immobilize and help promote healing. Finally, keeping the wound elevated will also reduce swelling and also help the healing process.

It is important to note that even minor injuries can vary in severity, with grade one being a minor injury and grade three requiring urgent care by a podiatrist. Achilles tendon ruptures and lacerations on the foot generally require urgent medical care and treatment options that need a podiatrist. These could include imaging tests, stitches for cuts, rehabilitation, and casts or braces. Every case is different, however, so it is always recommended to see a podiatrist when pain in the foot does not disappear.

While not a serious issue, toenail fungus, or onychomycosis, can be an embarrassing and uncomfortable condition to experience. Toenail fungus is often caused from public areas that harbor fungi and improper cleaning/drying of the foot. Once infected, the fungus grows deeper into the nail and can be very hard to get rid of.

There are different types of fungus that cause toenail fungus. Dermatophytes, yeasts, and molds are the most frequent forms of fungus to infect the toenail. Dermatophytes are the most common among the three. Symptoms associated with fungal nails include the discoloration of the toenail, brittleness, and in some circumstances, a smell. Pain is rarely a symptom caused by toenail fungus.

Diagnosis of fungal nails is generally a rather quick process. However podiatrists will make sure that the cause is not another condition such as lichen planus, psoriasis, onychogryphosis, or nail damage. Podiatrists will make use of fungal cultures and microscopy to verify that it is fungus.

While over-the-counter ointments are readily available, most are ineffective. This is due to the fact that the nail is very protective and that the fungus slips in between the nail plate and bed. Podiatrists can offer oral medication which currently provides the best results.

Ultimately, prevention is the best line of defense against toenail fungus. Avoid unsanitary public showers. If you do use a public shower, use shower shoes to provide your foot with protection. Once you are finished showering, make sure to thoroughly dry your feet. Fungi thrive in warm, dark, and moist places like sweaty, warm feet that are left dark in shoes all day.

Foot care is important regardless of your profession, but those who work on their feet must pay special attention. Bunions, calluses, blisters, and plantar warts are just a few of the many conditions that can arise after standing all day. While painful at their worst, these conditions can easily be avoided with the right foot care. This includes both appropriate footwear and proper posture—important elements that affect the health of your feet.

Choosing appropriate footwear means choosing a shoe that has a negative heel. This means that the heel is slightly lower than the ball of your foot, which places less of a strain. If you have a profession that requires you to be on your feet all day, investing in a pair of high-quality shoes is pertinent. High-quality shoes can be purchased from a respected manufacturer that emphasizes foot care and foot health.

Despite the regularity of wearing shoes, the feet are naturally not designed to be enclosed. Regular “barefoot” time for your feet can be beneficial for foot health. Among other methods, allowing your feet to breathe can help alleviate the pain and pressure your feet may be experiencing from being on your feet all day.

Simple foot exercises and yoga positions can help improve both the health and function of your feet. Active foot exercises that create movement will stimulate your foot’s blood flow and circulation, and yoga positions that place your feet flat onto the floor will stretch out their muscles. Yoga is particularly beneficial for your Achilles tendon and calf muscles, which are areas that can become especially problematic if not taken care of. Foot exercises and yoga positions can be easily performed every day at virtually any location and any time; whether it is at the office, at the gym, or at home right before you go to bed. Simple stretching can increase your foot health by miles.

The foot pain you experience after lengthy hours working on your feet may seem inevitable and unavoidable; in reality, however, that is not the case. Wearing proper footwear and performing simple foot exercises and stretches can help ease foot pain and allow you to truly avoid frustrating foot problems.

Your feet can easily be kept healthy with some education and a little effort. Pain that begins at the feet can eventually affect the whole body. Begin taking care of your feet now!
