Fox News Digital reached out to two podiatrists for their professional advice, including treatment of existing blisters and prevention of future sores.

ASK A DOCTOR: ‘HOW CAN I GET RID OF A COLD SORE AS QUICKLY AS POSSIBLE?’

Here’s how to put your best foot forward this summer.

What causes foot blisters?

In most cases, blisters develop on the feet due to ill-fitting shoes — but they can also stem from medical conditions.

Excessive friction is the most common cause, according to Dr. Alex Kor, a podiatrist with Hendricks Regional Health in Danville, Indiana. 

This can come from increased activity in a short period of time, often from wearing new shoes that haven’t been broken in yet, the doctor told Fox News Digital.

Blisters can also occur when a bony pressure point, such as a bunion, gets too much friction from a new shoe or excessive activity in a short period of time.

Other potential causes include going without socks, wearing worn-out socks or choosing improper shoes that do not offload a source of pressure, Kor warned.

Some medical issues may also cause blisters. 

“Depending on the patient’s medical status, conditions like diabetes and neuropathy can be the cause,” Kor told Fox News Digital. 

“Regardless of the reason for the blister, patients who have poor blood flow to the feet, diabetes or neuropathy should likely consider seeing a podiatrist.”

Ways to treat a foot blister

If you do develop a foot blister, keeping it clean will speed up the healing process, experts say.

“It is highly suggested to cleanse the blister with soapy water, dry the area and cover it with a dressing on a daily basis,” said Kor.

It’s not a good idea to skip the dressing and allow the site to “get air,” the doctor said.

If your foot blister was due to friction, Kor recommended avoiding the shoes or activity that caused the problem.

If a blister is accompanied by itching, there is the strong possibility that fungus could be the culprit, according to Kor. 

“A topical over-the-counter antifungal cream or ointment is suggested if the fungus is on the top, bottom or side of foot, and an antifungal powder is suggested if the blister is between the toes,” he advised.

When should you seek medical attention?

Patients should see a doctor if they have poor blood flow to the feet, diabetes, neuropathy or a history of previous amputations, according to Kor.

A doctor should also be involved if the blisters are accompanied by chills, fever, night sweats and/or red streaks coming from the area, which can be signs of infection.

You should also call a doctor if the blister has pus or yellow drainage; if the surrounding skin is red, hot and swollen; or if the blister is caused by a sunburn or frostbite, according to Dr. Saylee Tulpule, a podiatrist with Foot and Ankle Specialists of the Mid-Atlantic in the Washington, D.C. metro area.

Preventing blisters during summer travel

If your summer travel plans involve going to theme parks, hiking or lots of walking, proper foot care is essential to prevent blisters, experts agree. 

“It is also important to carry a first-aid kit during travel to manage any bleeding or pain, including topical antibiotic, gauze, tape and bandages,” an expert advised. (iStock)

“To prevent blisters during summer travel, it is important to wear properly fitted shoes or sandals,” Tulpule told Fox News Digital.

“I always tell my patients to visit a shoe store or running store and find the right length and width — and always break in new shoes for three to four weeks prior to traveling.”

To further protect feet, Tulpule recommended adding moleskin padding to shoes or taping it to the skin to prevent rubbing. 

“It is also important to carry a first-aid kit during travel to manage any bleeding or pain, including topical antibiotics, gauze, tape and bandages,” she added.

One walking habit could signal a healthier brain after 80, scientists say

One walking habit could signal a healthier brain after 80, scientists say

NEWYou can now listen to Fox News articles!

Older adults identified as “super movers” are about half as likely to develop cognitive impairment than their peers.

That’s according to a recent study led by Stony Brook Medicine in New York, which evaluated the cognitive function of 4,000 adults 80 and over who participated in multiple aging and longevity studies over several years.

Among this group, 6% to 10% were classified as super movers, which means they walk at a much faster pace than others of the same age and gender — at speeds comparable to people three decades younger.

COMMON VITAMIN MAY INFLUENCE BRAIN AGING IN WAYS SCIENTISTS DIDN’T EXPECT

The super movers were found to have about half the risk of cognitive decline compared to seniors with typical gait speed.

The findings were published in the journal Neurology on June 16.

“The study reinforces that mobility and brain health are closely connected,” lead study author Dr. Joe Verghese, MD, neurologist at Stony Brook Medicine, told Fox News Digital. “This suggests that preserving mobility may be an important marker of healthy brain aging and resilience.”

The most intriguing finding, according to Verghese, was that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.

In postmortem brain analysis, there was no difference in dementia-related pathologies between the super movers and the slower walkers, the study stated.

“This suggests they may possess resilience mechanisms that help preserve brain function even in the presence of age-related changes,” he said. “Understanding these resilience factors could lead to new strategies for promoting healthy brain aging.”

As the study was observational, there were some limitations, and it does not prove that walking faster prevents dementia, the researchers noted.

“Other factors, such as cardiovascular health, physical fitness or genetics, may also contribute to both faster walking and better cognitive outcomes,” Verghese said.

This study adds to growing evidence that what’s good for the heart and muscles also benefits the brain, he noted, adding that “staying physically active remains one of the most effective, evidence-based ways to support healthy aging.”

“Walking speed is best viewed as a marker of overall health, not a treatment.”

“The broader message is that physical activity is important at any age,” Verghese said. “Walking is an easy step-up point because you don’t need any special equipment. You can do it inside or outdoors, and you can do it on a regular basis. You can walk with a dog, you can walk with a friend.”

Any activity is beneficial if it’s done regularly and with the right intensity, he added.

Rather than just trying to walk faster, the neurologist recommends that seniors focus on maintaining mobility through regular physical activity, strength training, balance exercises and good cardiovascular health.

“Walking speed is best viewed as a marker of overall health, not a treatment,” Verghese noted.

Major public health guidelines from the CDC and U.S. Physical Activity Guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.

This can be achieved by walking 30 minutes a day, five days a week, or about 20 to 25 minutes most days. Another option is to engage in shorter sessions that add up over the day.

“You have to do it within your health limitations and medical conditions,” Verghese advised. “So if there are any medical concerns, I would get your physician to clear you before starting exercise.” The good thing about walking, he added, is that you can start at a slow pace and then gradually build up to a brisker pace.

“And then adding on strength and balance training, whatever age you are, I think is also important.”

Dr Oz warns Medicare scammers are stealing billions — and your personal information could be next

NEWYou can now listen to Fox News articles!

Medicare fraud is a multibillion-dollar problem that government officials say threatens both taxpayer dollars and Americans’ personal identities.

In a July 6 interview with Fox News Digital at the Great American State Fair in Washington, D.C., Dr. Mehmet Oz warned that every dollar stolen through Medicare fraud is a dollar taxpayers lose – a problem that has worsened since the COVID pandemic.

“If I had to just pick one thing to focus on to make healthcare more affordable in America, I’d go to health fraud and all the waste and abuse that accompanies it,” said Oz, who is the administrator of the Centers for Medicare & Medicaid Services. “And just to put this in perspective, we think it’s about $100 billion a year.”

Medicare fraud can include billing for services that were never provided, overcharging for medical equipment, using stolen patient or doctor information, or performing unnecessary procedures, according to the U.S. Government Accountability Office.

As the Trump administration ramped up efforts to combat fraud, CMS reported $41.9 billion in Medicare program integrity savings in 2025, up 59% from $26.3 billion in 2024.

Medicare fraud not only harms the federal budget and steals from taxpayers, but exposes seniors to identity theft, unnecessary care, higher premiums and reduced access, Oz cautioned.

Removing corruption from the healthcare system will have the greatest impact among seniors, since “so much of the fraud is perpetrated against them,” the administrator said.

“I’m talking about people tricking seniors to give up their Medicare beneficiary numbers, which is like a credit card basically,” he said. “These scammers can take those numbers and use them for all kinds of illegitimate purposes.”

“People are stealing from you by pretending to send you drugs you don’t want, wheelchairs you don’t need, [and] services you never asked for or don’t benefit from,” Oz added.

To prevent this, he shared his top advice for seniors: Do not give your Medicare beneficiary number to anybody, do not answer questions on a phone call from an unknown person and do not give away personal information.

“These scammers are calling seniors, tricking them, and once they have key information, they can steal it,” he said. “And I won’t know it and you won’t know it.”

“We want to protect people who need these programs the most,” Oz went on. “You do that by making sure scoundrels don’t corrupt the systems and steal money out of the till that is designed to help folks in dire straits when they’re vulnerable and in need of services.”

Removing fraud could “double the life expectancy of the trust fund that makes all this possible,” Oz predicted.

“If you’re worried about Medicare being there when you’re ready to retire in a couple decades, depending on how old you are, and you’re concerned that it might not last because of all the fraud that’s hitting it … you’ve got a good [reason to] worry,” he said.

“If we take the fraud out, we could double the life expectancy, which means you, your kids, your kids’ kids … they could all benefit from this beautiful safety net program.”
