Causes and Risks of Blisters on the Feet

Foot blisters form when friction or pressure causes the outer layers of the skin to separate, leading to the formation of a small pocket of fluid. This often happens from wearing shoes that do not fit or from excessive walking or running, increasing the likelihood of skin irritation. Blisters act as the body’s natural defense, protecting the underlying skin while it heals. Wearing shoes that are too tight, damp socks, or having an irregular foot shape can increase the risk of blisters. While most blisters heal on their own, recurrent or painful blisters may signal an underlying issue. A podiatrist can prescribe custom orthotics or recommend footwear changes that can help to prevent further occurrences. For those with conditions like diabetes, a podiatrist’s guidance is especially important to prevent infections and ward off more serious complications. If you frequently have blisters on your feet, it is suggested that you schedule an appointment with a podiatrist to find out why.
Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Barbara J. Aung, DPM of Aung Foot Health Clinic . Our doctor can provide the care you need to keep you pain-free and on your feet.
Foot Blisters
Foot blisters develop as a result of constantly wearing tight or ill-fitting footwear. This happens due to the constant rubbing from the shoe, which can often lead to pain.
What Are Foot Blisters?
A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.
How Do Blisters Form?
Blisters on the feet are often the result of constant friction of skin and material, usually by shoe rubbing. Walking in sandals, boots, or shoes that don’t fit properly for long periods of time can result in a blister. Having consistent foot moisture and humidity can easily lead to blister formation.
Prevention & Treatment
It is important to properly care for the affected area in order to prevent infection and ease the pain. Do not lance the blister and use a Band-Aid to provide pain relief. Also, be sure to keep your feet dry and wear proper fitting shoes. If you see blood or pus in a blister, seek assistance from a podiatrist.

Blisters
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.
Arthritis Can Cause Pain in the Feet and Ankles
The Impact of Footwear on Biomechanics

Footwear plays a significant role in foot biomechanics, influencing how your body moves and functions. High heels, for example, shift weight forward, altering the natural alignment of the spine and increasing pressure on the forefoot. This can lead to discomfort and long-term issues such as bunions or plantar fasciitis. On the other hand, flip flops offer minimal support, allowing the foot to overextend with each step, which can result in instability and strain on the muscles and ligaments. Lack of arch support in flip flops can worsen conditions like flat feet. Understanding how different types of footwear affect your biomechanics helps in making informed choices. Selecting shoes that provide adequate support, cushioning, and alignment can significantly improve comfort and reduce the risk of injuries, promoting healthier movement patterns overall. If you have developed foot pain from wearing shoes that do not align with your foot structure, it is suggested that you consult a podiatrist who can treat various foot conditions, and guide you toward making correct shoe choices.

Biomechanics in Podiatry
Podiatric biomechanics is a particular sector of specialty podiatry with licensed practitioners who are trained to diagnose and treat conditions affecting the foot, ankle and lower leg. Biomechanics deals with the forces that act against the body, causing an interference with the biological structures. It focuses on the movement of the ankle, the foot and the forces that interact with them.
A History of Biomechanics
- Biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded.
- In 1974, biomechanics gained a higher profile from the studies of Merton Root, who claimed that by changing or controlling the forces between the ankle and the foot, corrections or conditions could be implemented to gain strength and coordination in the area.
Modern technological improvements are based on past theories and therapeutic processes that provide a better understanding of podiatric concepts for biomechanics. Computers can provide accurate information about the forces and patterns of the feet and lower legs.
Understanding biomechanics of the feet can help improve and eliminate pain, stopping further stress to the foot.

Biomechanics in Podiatry
Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.
Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.
At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.
Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates. They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.
Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.
Tingling and Numb Feet

Peripheral neuropathy is a nerve damage condition that frequently accompanies diabetes and can lead to significant foot problems. This condition often manifests as tingling, a pins and needles sensation, burning pain, or numbness in the feet. In severe cases, it can result in reduced mobility, foot deformities, and even ulcers. Managing peripheral neuropathy involves addressing these symptoms and preventing complications. If you are experiencing any of these things or have concerns about your foot health, it is important to seek professional help. A podiatrist can conduct a thorough examination of your feet to diagnose peripheral neuropathy and recommend appropriate treatments to manage pain and improve your quality of life. For expert advice and personalized care, it is suggested you scheudle an appointment with a podiatrist.
Neuropathy
Neuropathy can be a potentially serious condition, especially if it is left undiagnosed. If you have any concerns that you may be experiencing nerve loss in your feet, consult with Barbara J. Aung, DPM from Aung Foot Health Clinic . Our doctor will assess your condition and provide you with quality foot and ankle treatment for neuropathy.
What Is Neuropathy?
Neuropathy is a condition that leads to damage to the nerves in the body. Peripheral neuropathy, or neuropathy that affects your peripheral nervous system, usually occurs in the feet. Neuropathy can be triggered by a number of different causes. Such causes include diabetes, infections, cancers, disorders, and toxic substances.
Symptoms of Neuropathy Include:
- Numbness
- Sensation loss
- Prickling and tingling sensations
- Throbbing, freezing, burning pains
- Muscle weakness
Those with diabetes are at serious risk due to being unable to feel an ulcer on their feet. Diabetics usually also suffer from poor blood circulation. This can lead to the wound not healing, infections occurring, and the limb may have to be amputated.
Treatment
To treat neuropathy in the foot, podiatrists will first diagnose the cause of the neuropathy. Figuring out the underlying cause of the neuropathy will allow the podiatrist to prescribe the best treatment, whether it be caused by diabetes, toxic substance exposure, infection, etc. If the nerve has not died, then it’s possible that sensation may be able to return to the foot.
Pain medication may be issued for pain. Electrical nerve stimulation can be used to stimulate nerves. If the neuropathy is caused from pressure on the nerves, then surgery may be necessary.

Neuropathy
Neuropathy is a condition in which the nerves in the body become damaged from a number of different illnesses. Nerves from any part of the body, including the foot, can be damaged. There are several forms of neuropathy including peripheral neuropathy, cranial neuropathy, focal neuropathy, and autonomic neuropathy. Furthermore there is also mononeuropathy and polyneuropathy. Mononeuropathies affect one nerve while polyneuropathies affect several nerves. Causes of neuropathy include physical injury, diseases, cancers, infections, diabetes, toxic substances, and disorders. It is peripheral neuropathy that affects the feet.
The symptoms of neuropathy vary greatly and can be minor such as numbness, sensation loss, prickling, and tingling sensations. More painful symptoms include throbbing, burning, freezing, and sharp pains. The most severe symptoms can be muscle weakness/paralysis, problems with coordination, and falling.
Podiatrists rely upon a full medical history and a neurological examination to diagnose peripheral neuropathy in the foot. More tests that may be used include nerve function tests to test nerve damage, blood tests to detect diabetes or vitamin deficiencies. Imaging tests, such as CT or MRI scans, might be used to look for abnormalities, and finally nerve or skin biopsies could also be taken.
Treatment depends upon the causes of neuropathy. If the neuropathy was caused by vitamin deficiency, diabetes, infection, or toxic substances, addressing those conditions can lead to the nerve healing and sensation returning to the area. However if the nerve has died, then sensation may never come back to the area. Pain medication may be prescribed for less serious symptoms. Topical creams may also be tried to bring back sensation. Electrical nerve stimulation may be used for a period of time to stimulate nerves. Physical therapy can strengthen muscle and improve movement. Finally surgery might be necessary if pressure on the nerve is causing the neuropathy.
If you are experiencing sensation loss, numbness, tingling, or burning sensations in your feet, you may be experiencing neuropathy. Be sure to talk to a podiatrist to be diagnosed right away.
Benefits of Minimally Invasive Bunionectomies

Minimally invasive bunionectomies are transforming the approach to treating bunions, offering a less disruptive alternative to traditional surgery. Unlike conventional procedures, which involve large incisions and a lengthy recovery period, minimally invasive techniques use small incisions and specialized instruments to realign the bones. This results in less tissue damage, reduced scarring, and faster recovery times. Patients typically experience less postoperative pain and are able to resume normal activities sooner than with traditional surgery. Another advantage is a lower risk of complications, such as infection or stiffness, due to the minimally invasive nature of the procedure. It offers a more patient-friendly option with similar long-term outcomes. If you are seeking quicker recovery and less disruption to your daily life from bunion surgery, it is suggested that you visit a podiatrist to see if this minimally invasive procedure will work for you.
Foot surgery is sometimes necessary to treat a foot ailment. To learn more, contact Barbara J. Aung, DPM of Aung Foot Health Clinic . Our doctor will assist you with all of your foot and ankle needs.
When Is Surgery Necessary?
Foot and ankle surgery is generally reserved for cases in which less invasive, conservative procedures have failed to alleviate the problem. Some of the cases in which surgery may be necessary include:
- Removing foot deformities like bunions and bone spurs
- Severe arthritis that has caused bone issues
- Cosmetic reconstruction
What Types of Surgery Are There?
The type of surgery you receive will depend on the nature of the problem you have. Some of the possible surgeries include:
- Bunionectomy for painful bunions
- Surgical fusion for realignment of bones
- Neuropathy decompression surgery to treat nerve damage
Benefits of Surgery
Although surgery is usually a last resort, it can provide more complete pain relief compared to non-surgical methods and may allow you to finally resume full activity.
Surgical techniques have also become increasingly sophisticated. Techniques like endoscopic surgery allow for smaller incisions and faster recovery times.

Foot and Ankle Surgery
When conservative, noninvasive methods prove ineffective, surgery may be selected as the next course of action for the treatment of your foot or ankle condition. A wide number of foot and ankle surgical procedures exist, and it is up to your podiatrist to determine which intervention will be most appropriate and helpful for your case. Some surgical procedures include bunion surgery, fusion, hammertoe surgery, heel spur surgery, metatarsal surgery, nail surgery, neuroma surgery, reconstructive surgery, skin surgery, and tendon surgery. Typically, surgery is turned to as a definitive way to alleviate excessive pain or discomfort and to return your foot to full mobility.
Regardless of the location on the body, all surgical procedures require preoperative testing and examination to ensure the surgery’s success and preferred outcome. A review of your medical history and medical conditions will take place, as will an evaluation of any current diseases, illnesses, allergies, and medications. Tests such as blood studies, urinalyses, EKG, X-rays, and blood flow studies may be ordered. Because the procedure involves the foot and/or ankle, the structures of your feet while walking may also be observed by your podiatrist.
Care post-surgery will depend on the type of surgical procedure performed. Typically, all postoperative care involves rest, ice, compression, and elevation. To improve and ensure a safe recovery, your foot and ankle surgeon may also employ the use of bandages, splints, surgical shoes, casts, crutches, or canes. He will also determine if and when you can bear weight. A timely and thorough recovery is a priority for both you and your podiatrist, and carefully following postoperative instructions can help achieve this.
Foot Problems From Diabetic Patients

Foot problems are a common and serious concern for individuals with diabetes, often leading to complications like diabetic foot ulcers. Diabetes can cause nerve damage and poor blood circulation, making the feet more prone to injuries that might go unnoticed due to reduced sensation. The lack of feeling increases the risk of wounds, blisters, and ulcers, which can worsen without proper care. Diabetic foot ulcers can take a long time to heal and may lead to infections if not treated properly. Podiatrists play a vital role in managing diabetes related foot issues. They can perform necessary treatments, such as debridement to remove dead tissue, suggest appropriate footwear to alleviate pressure on affected areas, and provide wound care solutions. If you have a foot problem related to diabetes, it is suggested that you schedule an appointment with a podiatrist for regular monitoring and care.
Diabetic foot care is important in preventing foot ailments such as ulcers. If you are suffering from diabetes or have any other concerns about your feet, contact Barbara J. Aung, DPM from Aung Foot Health Clinic . Our doctor can provide the care you need to keep you pain-free and on your feet.
Diabetic Foot Care
Diabetes affects millions of people every year. The condition can damage blood vessels in many parts of the body, especially the feet. Because of this, taking care of your feet is essential if you have diabetes, and having a podiatrist help monitor your foot health is highly recommended.
The Importance of Caring for Your Feet
- Routinely inspect your feet for bruises or sores.
- Wear socks that fit your feet comfortably.
- Wear comfortable shoes that provide adequate support.
Patients with diabetes should have their doctor monitor their blood levels, as blood sugar levels play such a huge role in diabetic care. Monitoring these levels on a regular basis is highly advised.
