Treating Blisters on the Feet

A blister on the foot is a fluid‑filled bubble that forms when the upper skin layers separate and fill with serum. Blisters most often occur on the feet, toes, or ankles due to friction from wearing ill‑fitting footwear, hotspots from repetitive pressure, moisture, or foot shape issues. The body creates blisters as a temporary shield to protect deeper skin and slow down activity by causing discomfort. Clean, dry socks, properly fitted shoes, and keeping the area clean and protected with a dressing or blister pad can speed the process. Popping a blister is unwise because it breaks the natural barrier, which increases the risk of infection and exposes sensitive skin beneath. A podiatrist can assess the extent of the blister, treat any infection, recommend appropriate dressings, and suggest footwear or pressure‑point adjustments to prevent recurrence. If you have problematic blisters on your feet, it is suggested that you schedule an appointment with a podiatrist for safe and sterile treatment.
Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Renee Rodriquez, DPM of Foot Clinic of South Texas. 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.
Causes and Symptoms of Psoriatic Arthritis in the Feet

Psoriatic arthritis is an inflammatory condition linked to psoriasis that often affects the feet and toes. It can develop when the immune system mistakenly attacks healthy joints and tissues. Common causes include genetic factors and immune system dysfunction. Symptoms in the feet may include joint pain, swelling, stiffness, and changes in toenails, such as pitting or separation from the nail bed. The inflammation can make walking difficult and painful. A podiatrist can help by evaluating joint function, managing inflammation, recommending supportive footwear or orthotics, and coordinating care with other specialists. If you experience persistent foot pain with a history of psoriasis, it is suggested that you are under the care of a podiatrist to receive expert care, while improving your mobility.
Arthritis can be a difficult condition to live with. If you are seeking treatment, contact Renee Rodriquez, DPM from Foot Clinic of South Texas. Our doctor can provide the care you need to keep you pain-free and on your feet.
Arthritic Foot Care
Arthritis is a joint disorder that involves the inflammation of different joints in your body, such as those in your feet. Arthritis is often caused by a degenerative joint disease and causes mild to severe pain in all affected areas. In addition to this, swelling and stiffness in the affected joints can also be a common symptom of arthritis.
In many cases, wearing ill-fitting shoes can worsen the effects and pain of arthritis. Wearing shoes that have a lower heel and extra room can help your feet feel more comfortable. In cases of rheumatoid arthritis, the arch in your foot may become problematic. Buying shoes with proper arch support that contour to your feet can help immensely.
Alleviating Arthritic Pain
- Exercises that stretch the foot can prevent further pain and injury and increase mobility
- Most of the pain can be alleviated with anti-inflammatory drugs, heat, and topical medications
- Massages can help temporarily alleviate pain.
It is best to see your doctor for the treatment that is right for your needs and symptoms. Conditions vary, and a podiatrist can help you determine the right method of care for your feet.

Arthritic Foot Care
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.
How Diabetes Affects Children's Feet

Diabetes can have serious effects on children's feet by increasing the risk of infections, reducing blood flow, and causing nerve damage. Poor circulation can delay healing, while nerve damage may lead to reduced sensation, making it harder for a child to notice injuries, blisters, or cuts. These issues can lead to complications if not addressed early. A podiatrist can help by performing regular foot checks, providing education on proper foot care, and recommending footwear that offers protection and support. If your child has diabetes, it is suggested that you schedule routine visits with a podiatrist to support healthy feet and overall well-being.
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 Renee Rodriquez, DPM from Foot Clinic of South Texas. 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.
It is always best to inform your healthcare professional of any concerns you may have regarding your feet, especially for diabetic patients. Early treatment and routine foot examinations are keys to maintaining proper health, especially because severe complications can arise if proper treatment is not applied.

How to Care for Diabetic Foot
Millions of people are affected by diabetes each year. Diabetes damages blood vessels in all parts of the body, especially the feet. The legs and feet may develop slow blood flow, which causes neuropathy, or nerve damage. Once a diabetic patient develops neuropathy, it is important that the feet are well taken care of. Otherwise, the lower limbs may have to be amputated. This only happens in drastic cases, but it shows how seriously diabetic foot care should be taken.
It is very important to always wash and dry the feet thoroughly, especially in between the toes, if you’re a diabetic. Secondly, examining your feet and toes for redness or sores must be done, even if you do not feel pain. You may also want to examine your feet from the bottom. Try to avoid wearing colored socks to prevent infections that may occur from the dye. Well-fitting socks are also highly recommended.
A diabetic’s physician should always monitor their blood levels to test how well blood sugars are being maintained. In addition to giving advice about everyday eating habits and foot care, a physician may prescribe medicine to help with the diabetic patient’s neuropathy. It is also advised to see a podiatrist if experiencing any feet conditions. Toenails may also need to be taken care of by a podiatrist. This prevents patients from cutting too deeply around their cuticles, which can lead to infection.
A person can take care of their feet at home by following the instructions of their physician. Using creams on one’s feet is also an effective way to heal dryness. Proceed with caution when using tools to remove calluses, as severe diabetics may not be able to feel pain on their feet. If any complications arise do not hesitate to contact a podiatrist.
On a daily basis, diabetic feet must be checked. If you are ever concerned about something, contact your health care professional. You never want to wait until a wound becomes too severe to treat. If left untreated, gangrene may develop. Gangrene is a serious infection that can lead to sepsis or amputation. It is also important for diabetics to be on the lookout for ulcers. Ulcers are sores that develop from tissue loss on the skin. They can be quite painful and require intensive treatment. Early treatment and everyday inspection are imperative to staying healthy.
When Children Step on Sharp Objects

Young children often run barefoot or in thin shoes, which makes stepping on sharp objects more common than many parents expect. Whether it is a splinter, nail, or shard of glass, puncture wounds to the bottom of the foot can be more serious than they first appear. These injuries may seem small on the surface but can drive debris deep into soft tissue, increasing the risk of infection or damage to deeper structures. Early signs such as swelling, redness, or limping should not be ignored. Proper cleaning is important, but some wounds may require medical attention, especially if the object was dirty or the child is overdue for a tetanus shot. If your child has pain or difficulty walking after a puncture wound, it is suggested that you see a podiatrist as quickly as possible for a complete evaluation and care plan.
Wound care is an important part in dealing with diabetes. If you have diabetes and a foot wound or would like more information about wound care for diabetics, consult with Renee Rodriquez, DPM from Foot Clinic of South Texas. Our doctor will assess your condition and provide you with quality foot and ankle treatment.
What Is Wound Care?
Wound care is the practice of taking proper care of a wound. This can range from the smallest to the largest of wounds. While everyone can benefit from proper wound care, it is much more important for diabetics. Diabetics often suffer from poor blood circulation which causes wounds to heal much slower than they would in a non-diabetic.
What Is the Importance of Wound Care?
While it may not seem apparent with small ulcers on the foot, for diabetics, any size ulcer can become infected. Diabetics often also suffer from neuropathy, or nerve loss. This means they might not even feel when they have an ulcer on their foot. If the wound becomes severely infected, amputation may be necessary. Therefore, it is of the upmost importance to properly care for any and all foot wounds.
How to Care for Wounds
The best way to care for foot wounds is to prevent them. For diabetics, this means daily inspections of the feet for any signs of abnormalities or ulcers. It is also recommended to see a podiatrist several times a year for a foot inspection. If you do have an ulcer, run the wound under water to clear dirt from the wound; then apply antibiotic ointment to the wound and cover with a bandage. Bandages should be changed daily and keeping pressure off the wound is smart. It is advised to see a podiatrist, who can keep an eye on it.

Wound Care
Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.
Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound. To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.
To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.
Foot and Ankle Pain Caused by Running

Foot and ankle pain from running is a frequent problem, often caused by repeated stress and small imbalances in how the feet move. Runners put a lot of pressure on their feet with every step, which can lead to soreness. This is especially true if they increase distance too quickly, wear worn-out shoes, or return to running too soon after an injury. Common running injuries include stretched or torn ligaments from twisting an ankle, pain on the inner or outer sides of the ankle from overworked tendons, or aching at the back of the heel where the foot connects to the leg. Some runners feel sharp pain in the arch or bottom of the foot, while others may feel burning or tingling from pressure on nerves. A podiatrist can check how your foot moves, look for signs of overuse, and recommend proper treatment. If you are experiencing pain after running, it is suggested that you schedule an appointment with a podiatrist for a diagnosis and appropriate treatment.
All runners should take extra precaution when trying to avoid injury. If you have any concerns about your feet, contact Renee Rodriquez, DPM of Foot Clinic of South Texas. Our doctor will treat your foot and ankle needs.
How to Prevent Running Injuries
There are a lot of mistakes a runner can make prior to a workout that can induce injury. A lot of athletes tend to overstretch before running, instead of saving those workouts for a post-run routine. Deep lunges and hand-to-toe hamstring pulls should be performed after a workout instead of during a warmup. Another common mistake is jumping into an intense routine before your body is physically prepared for it. You should try to ease your way into long-distance running instead of forcing yourself to rush into it.
More Tips for Preventing Injury
- Incorporate Strength Training into Workouts - This will help improve the body’s overall athleticism
- Improve and Maintain Your Flexibility – Stretching everyday will help improve overall performance
- “Warm Up” Before Running and “Cool Down” Afterward – A warm up of 5-10 minutes helps get rid of lactic acid in the muscles and prevents delayed muscle soreness
- Cross-Training is Crucial
- Wear Proper Running Shoes
- Have a Formal Gait Analysis – Poor biomechanics can easily cause injury
