Cold sores are a common and often frustrating skin issue. While they may look like harmless blisters, cold sores are actually caused by the herpes simplex virus (HSV).

What Causes Cold Sores?

Cold sores are caused by the herpes simplex virus (HSV), which comes in two types: HSV-1 and HSV-2.

HSV-1 is the primary cause of cold sores, usually appearing around the mouth.

HSV-2 generally causes genital herpes but can also lead to cold sores.

While the appearance of cold sores caused by both HSV-1 and HSV-2 can look similar, their locations tend to differ. However, it is possible for HSV-1 to cause sores on the genitals and for HSV-2 to appear on the mouth.

How Do Cold Sores Spread?

Cold sores are highly contagious and can spread easily. The virus can be passed on through:

  • Kissing or skin contact
  • Sharing food, drinks, or cosmetics (such as lip balm)
  • Oral sex, which can spread both cold sores and genital herpes

Even when a cold sore isn’t visible, the virus can still be spread through close contact. This makes prevention and management key to reducing outbreaks and the risk of infecting others.

Once someone contracts HSV, it stays in the body for life. While the virus remains dormant most of the time, it can reactivate and cause new sores, especially during periods of:

  • Stress
  • Illness
  • A weakened immune system

Unfortunately, there’s no cure for the herpes virus, but the symptoms can be managed.

Symptoms of Cold Sores

Cold sores don’t just appear out of nowhere. Before the sore is visible, you may notice a tingling or burning sensation around the lips or face, which can occur several days before the sore forms. This is the best time to begin treatment to shorten the outbreak.

When a cold sore does appear, it often looks like a red, raised blister filled with fluid. The blister can be painful to touch, and there may be more than one. Cold sores usually last around two weeks and are contagious until they crust over and heal.

The Five Stages of a Cold Sore

Cold sores go through distinct stages as they develop and heal:

  • Tingling and itching: You may feel these symptoms about 24 hours before the blister appears.
  • Blisters: Small, fluid-filled blisters form, typically around the mouth.
  • Bursting: The blisters burst and form painful sores.
  • Scabbing: The sores dry out, scab over, and may itch or crack.
  • Healing: The scab falls off, and the cold sore heals.
Risk Factors for Cold Sores

Certain factors can trigger the reactivation of HSV, leading to cold sores. These include:

  • Infection, fever, or cold
  • Sun exposure
  • Stress
  • Menstruation
  • Dental work or injury
  • Weakened immune system due to conditions like HIV/AIDS, eczema, or chemotherapy
Anyone who comes in direct contact with the fluid from a cold sore—whether by kissing, sharing utensils, or using personal items like razors or toothbrushes—can contract the virus.

Managing and Treating Cold Sores

There’s no cure for cold sores, but several treatments can ease the symptoms and help manage outbreaks.

Topical Ointments and Creams

Over-the-counter antiviral creams like docosanol (Abreva) or prescription ointments like penciclovir (Denavir) can help reduce the duration of an outbreak, especially if applied at the first sign of a cold sore.

Oral Medications

Prescription antiviral medications like acyclovir, valacyclovir, and famciclovir can also help, particularly for people who have frequent or severe outbreaks. Your doctor may recommend taking these medications regularly to prevent future outbreaks.

Home Remedies

There are also some home remedies that may provide relief, such as:

  • Applying ice or a cold washcloth to the sore
  • Using aloe vera gel or lemon balm lip balms
  • Applying petroleum jelly to ease discomfort

Canker Sores vs. Cold Sores: What's the Difference?

While cold sores and canker sores may seem similar, they are quite different:

Cold sores are caused by the herpes virus, appear around the mouth, and are contagious.

Canker sores are not contagious and appear as ulcers inside the mouth or throat.

Preventing the Spread of Cold Sores

To avoid spreading cold sores:

  • Wash your hands frequently
  • Avoid close contact with others during an outbreak
  • Don’t share food, drinks, or personal items like lip balm
If certain triggers, like sun exposure or stress, cause your cold sores to flare up, take preventive steps, such as using sunblock on your lips or practicing stress management techniques like meditation.

Cold sores can be a persistent issue, but with proper care and management, you can reduce the frequency of outbreaks and prevent spreading the virus to others.

Amid rising summer temperatures, along with pollution, eye specialists today warned that the heat and dust can add stress on the eyes, leading to dryness, allergies, infections, and irritation.

Delhi witnessed its first official heatwave day of the month on Tuesday, as scorching sunshine and dry winds pushed temperatures beyond 45°C across several parts of the city.

The India Meteorological Department (IMD) warned that conditions are likely to worsen over the coming days, with temperatures expected to rise to nearly 46°C on May 20.

The weather department has also issued an orange alert for Delhi until May 25, cautioning residents about prolonged heatwaves and excessive heat conditions expected over six consecutive days.

Allergies, Dryness, and Infections Common In Summer

Speaking to HealthandMe, Dr. Bhavatharini M, Senior Consultant Ophthalmologist at Dr. Agarwal's Eye Hospital, said that summer conditions can significantly impact eye health.

“Summer places added stress on the eyes, particularly in cities like New Delhi where heat, dust, and pollution are significant factors,” she said.

Dr. Bhavatharini explained that common concerns during the season include dryness caused by increased tear evaporation while

  • watching screens,
  • allergies triggered by environmental irritants,
  • UV-related damage,
  • infections linked to swimming in poorly maintained pools.

Dr. Kalpana R, Senior Consultant, Ophthalmology at SIMS Hospital, also warned of problems that affect the eyes during this season, such as

  • allergies,
  • dryness,
  • seasonal infections,
  • viral and bacterial infections,
  • swimming pool infections,
  • migraine headaches.

She stressed the importance of maintaining proper hydration and following a balanced, nutritious diet to support eye health during the hotter months.

How To Prevent Eye Health In Scorching Summers

Dr. Bhavatharini advised people to take simple preventive measures, such as wearing UV-protective sunglasses, staying well-hydrated, avoiding rubbing their eyes, and using protective goggles while swimming.

“Persistent redness, irritation, or blurred vision should not be ignored and warrants timely evaluation by your eye specialist,” she added.

Dr. Kalpana further recommended wearing protective eyewear outdoors to shield the eyes from harmful UV rays and glare.

People travelling on bikes should wear helmets with visors to reduce exposure to dust and pollution, while swimmers should use swimming goggles to prevent infections and injuries associated with pool water.

For allergies, she advised people not to rub their eyes even if they experience itching.

“Just as a home remedy, you can use an ice pack over the closed eyelids or splash cold water over the closed eyelids to get some immediate relief,” she told HealthandMe.

Avoid Self-Medication

The experts also warned against self-medication in case of eye infections.

“And for viral infections and bacterial infections, if you feel that you get a sticky discharge and redness, you must immediately go to an ophthalmologist and get it treated. Never use over-the-counter medicines for any of your infections,” Dr. Kalpana said.

She added that people with common cold symptoms should wear masks and avoid touching commonly used surfaces if they have signs of an eye infection, as infections can spread through secretions.

American TV personality Kim Kardashian has opened up about the steps she takes to care for her health, including taking 35 supplements daily.

Speaking on a podcast, the 45-year-old mother admitted she suffers from “pill fatigue.”

“I take probably 35 supplements a day,” the reality star revealed. “I spread them out three times a day.”

The mother of four said she struggles particularly with fish oil supplements because of their lingering taste, and even wished there were an IV drip alternative available.

“I thought, ‘Okay, I can't do this fish oil anymore. I have pill fatigue. I have to stop these fish oil [supplements], and I got my bloodwork, and it was so evident that I stopped and I had to start again,” Kim said.

“I wish there was like an IV drip (for fish oil) I could do every day, and I would just do it on my way to work,” she added.

Further, Kim revealed that her family, including her mother, Kris Jenner, and sisters, regularly use DEXA scans to monitor bone density.

A DEXA scan (Dual-Energy X-ray Absorptiometry) is an imaging test that uses low-frequency X-rays to measure bone density and analyze total body composition, including lean muscle, fat mass, and visceral fat.

“I actually know a portable DEXA scan person that comes in a van, and you lie down,” she shared.

“Each one of my sisters and my mom — we all live in the same gated community — so we have the van drive by, and we all jump in the van, and you just lie down, and it scans your body maybe like three minutes. And it tells you all about your bone density.”

Kardashian also said she undergoes yearly scans with her family and is continuing to explore new wellness tools.

Kim's Diagnosis With Brain Aneurysm

Kim has also been diligent about monitoring her health in recent years. In a November 2025 episode of The Kardashians, she revealed that doctors had discovered a small aneurysm in her brain.

At the time, Kim explained that the aneurysm — a balloon-like bulge in a blood vessel in the brain — could be linked to the stress she had experienced over the years. She said her divorce from Kanye West, the responsibilities of being a single mother of four, her multiple business ventures, and studying law had all contributed to immense stress.

Shortly before that episode aired, Kim also discussed the aneurysm during an appearance on Good Morning America.

“It's just a good measure to go; make sure that you always check everything,” Kim said. “Health is wealth, and you just have to be careful with everything that you do.”

Untreated Spinal Stenosis Can Lead To Permanent Nerve Damage: Here’s How To Prevent

Updated May 20, 2026 | 07:00 AM IST

SummarySpinal stenosis involves the narrowing of one or more spaces within the spinal canal. It can develop due to age-related changes, herniated discs, thickened ligaments, or previous injuries, most commonly affecting the lower back and neck.

Persistent back pain is often ignored as a minor issue, but when it continues or worsens over time, it may be a sign of an underlying spinal condition. One such condition is spinal stenosis, which involves narrowing of one or more spaces within the spinal canal.

It can develop due to age-related changes, herniated discs, thickened ligaments, or previous injuries, most commonly affecting the lower back and neck. Since spinal stenosis progresses slowly and symptoms may appear mild at first, early detection becomes crucial to prevent long-term complications, including permanent nerve damage.

Why Is It Dangerous If Untreated?

In its early stages, spinal stenosis may cause mild discomfort, tingling, or numbness. However, as the narrowing worsens, pressure on the nerves increases. This can lead to chronic pain, weakness in the limbs, and difficulty walking or maintaining balance.

If ignored for a long time, the condition can result in permanent nerve damage. In severe cases, patients may experience loss of bladder or bowel control, a medical emergency that requires immediate attention. Delayed treatment reduces the chances of reversing nerve damage, making early recognition more important.

What Are The Warning Signs To Watch Out For?

While occasional back pain is common, certain symptoms indicate something more serious:

  • Persistent back or neck pain that worsens over time
  • Numbness or tingling in the arms, legs, or feet
  • Muscle weakness or reduced strength
  • Difficulty walking or maintaining balance
  • Pain that radiates down the legs, especially while standing or walking

How Can It Be Diagnosed?

Diagnosis of spinal stenosis focuses on identifying the extent of spinal narrowing and its impact on nerve function. It usually begins with a detailed assessment of symptoms and physical movement, followed by imaging tests such as spine X-rays, MRI, and CT scans.

In some cases, a CT myelogram may be advised for a more detailed view of the spinal canal and nerve compression. These tests help confirm the condition, locate the affected area, and determine its severity.

How Can It Be Treated?

Treatment depends on how advanced the condition is. In the early stages, simple measures are usually recommended, such as regular exercises like walking or stretching, correcting posture, making ergonomic changes in daily routine, maintaining a healthy weight, and avoiding activities that strain the spine.

However, in more severe cases where nerve compression significantly affects daily functioning, certain procedures may be required.

Minimally invasive spine decompression (MISD) is a modern surgical approach designed to alleviate pressure on spinal nerves while preserving as much of the natural spinal structure as possible. Unlike the traditional laminectomy, which often involves significant removal of bone and muscle, MISD focuses on precision and stability.

Spinal fusion joins two or more bones in the spine to improve stability and reduce excessive movement.

What Are The Tips To Prevent Spinal stenosis?

Preventing spinal stenosis or slowing its progression involves a combination of lifestyle changes and early care:

  • Stay physically active: Regular exercise helps strengthen the muscles supporting the spine and reduces strain.
  • Maintain good posture: Proper sitting and standing posture prevents unnecessary pressure on the spine.
  • Avoid prolonged sitting: Taking frequent breaks helps reduce stiffness and improve spinal flexibility.
  • Manage body weight: Excess weight increases pressure on the lower spine, worsening the condition.
  • Be mindful while lifting: Using correct techniques prevents sudden strain or injury to the spine.
Back pain should not always be taken lightly. What may seem like a minor issue could be an early sign of Spinal Stenosis.

Ignoring symptoms can lead to irreversible nerve damage and long-term disability. With early diagnosis, proper lifestyle changes, and expert care, it is possible to manage the condition effectively and maintain a good quality of life.
