If you are someone who cracks your knuckles every day just for that oddly satisfying pop, you are not alone. For many, the sharp sound brings a fleeting sense of relief or relaxation. Yet, there has long been a debate about whether this seemingly harmless habit could actually damage your joints or raise the risk of arthritis.

For those unversed, the pop you hear when cracking your knuckles comes from gas bubbles in the joint fluid collapsing. For most people, it’s harmless, though it can occasionally cause slight swelling or a temporary drop in grip strength. The long-standing belief that it leads to arthritis is not backed by science, but using too much force could result in minor injuries, like ligament sprains or dislocations

Addressing this common worry, orthopedic surgeon Dr. Manan Vora answered the question in a viral reel that has now surpassed 2.5 million views. A viewer asked him, “Can cracking knuckles every day lead to arthritis?”

Dr. Vora said, “The pop you hear when cracking a knuckle is the sound of these bubbles bursting within the synovial fluid inside the joint,” he clarified.

Is Cracking Knuckles Bad For You?

Knuckle cracking is a habit many pick up early in life, often because they enjoy the sound or the temporary feeling of looseness in the fingers. According to the Johns Hopkins Arthritis Center, the sound comes from changes inside the joint capsule, which is filled with synovial fluid. This fluid not only lubricates the joints but also nourishes the surrounding bones.

“A variety of gases are dissolved in this fluid. When a knuckle is cracked, stretching the capsule lowers the pressure inside, creating a vacuum. The dissolved gases form a bubble, which bursts, producing the familiar popping sound. It takes time for the gases to re-dissolve, which is why you can’t immediately crack the same knuckle again,” Johns Hopkins adds.

Does Cracking Knuckles Cause Arthritis?

Many worry that frequent knuckle cracking could trigger arthritis. However, research shows there is no evidence linking the habit to arthritis or long-term joint damage. A few reports have noted that excessive cracking may occasionally cause minor ligament strains or tendon dislocations, but these injuries typically heal on their own.

Some studies also suggest that habitual knuckle crackers might have slightly reduced grip strength over time, but this does not equate to arthritis. Rarely, “knuckle pads” can develop in young people who crack their knuckles often, but these are mostly cosmetic.

Several studies back up the conclusion that knuckle cracking does not cause arthritis. For example, a study by the Uniformed Services University of the Health Sciences followed 215 participants, 20% of whom regularly cracked their knuckles. They found arthritis in 18.1% of knuckle crackers and 21.5% of non-crackers, essentially the same rate, showing no link between the habit and the disease.

A famous anecdote comes from Dr. Donald Unger, who cracked the knuckles on his left hand twice daily for 50 years while leaving his right hand untouched. Published in Arthritis and Rheumatism in 1998, the informal experiment revealed that neither hand showed signs of arthritis. More recent studies in 2017 reached similar results, finding no difference in hand function between people who cracked their knuckles and those who didn’t.

What Is Arthritis?

Arthritis is a condition that causes inflammation and pain in one or more joints, often leading to stiffness and limiting the joint’s range of motion. Genetics play a major role, with environmental triggers contributing to inflammatory types, and age or mechanical stress driving degenerative arthritis.

Other risk factors include obesity, previous joint injuries, family history, older age, and being female. But as research confirms, knuckle cracking is not one of them.

Sepsis that happened by a lick from a pet dog led to a woman losing all four of her limbs. Health and Me had previously reported that a Birmingham based woman, 56-year-old pharmacy worker Manjit Sangha caught sepsis from the lick of her pet dog. She spent her night in coma in the hospital and had to lose all her limbs. This happened because bacteria from dog's lick entered her body through a cut or a scratch. This led to sepsis, where the immune system's reaction to infection damaged the body's own tissues and organs.

This has brought a lot of attention on what sepsis is and what are the symptoms one must be aware of. As per the Sepsis Alliance, one must know about TIME to be aware of sepsis.

Unique Symptoms of Sepsis

TIME stands for temperature, infection, mental decline and extremely ill. If you notice these symptoms, rush to the hospital.

• T for Temperature: If you notice your body temperature rising or falling
• I for Infection: If you see signs or symptoms of any infection
• M for Mental Decline: If you feel confused, sleepy and difficult in rising
• E for Extremely Ill: If you feel severe pain, discomfort, shortness of breath

Unique Symptoms Of Sepsis: What To Know About Temperature

Your body temperature normally stays steady at about 98.6°F (37°C), with small changes based on activity, surroundings, and time of day. A reading of 100°F (37.7°C) or higher is considered a fever. During infection, the body often heats up to help fight germs. However, some people experience an unusual drop in temperature instead. Because of this, both a spike and a fall in temperature can be warning signs of sepsis.

When an infection stays in one area, its symptoms usually match the site involved. A urinary tract infection may cause burning while urinating or frequent urges, pneumonia can bring cough and chest pain, and an infected cut may show redness or pus.

If the infection spreads through the body, broader symptoms like fever, tiredness, and body aches can appear. In some cases, an infection may not cause obvious symptoms at all. This is especially important to remember after surgery, medical procedures, skin injuries, or close contact with someone who is sick.

Sepsis can also alter how the brain functions. Some people, particularly older adults, may not develop the usual infection symptoms. Instead, they might suddenly become confused or show a sharp worsening of existing dementia. Marked drowsiness or unusual sleepiness is another common sign.

Unique Symptoms of Sepsis: Signs That You Are Extremely Ill

Many sepsis survivors recall feeling sicker than ever before. They describe overwhelming symptoms such as the most severe sore throat or abdominal pain they had experienced, along with a frightening sense that they might not survive.

Mounjaro, a popular weight loss drug that helped many lose weight, however, in this one case, a woman, who was on the same drug noticed something different. While she lost weight, she noticed that her breasts continued to grow. The 30-year-old Tianna Moon of East Anglia, a region in eastern England first realized something was not normal with her chest in 2024. This was when she started to use Mounjaro.

She was losing weight, but her breasts continued to grow. This is when Moon's doctor diagnosed her with a rare disease call gigantomastia, which causes breast tissue to grow rapidly and in excess.

Woman Lost Weight On Mounjaro But Her Breasts Didn't Stop Growing: What Happened To Her?

Moon said that the doctors had thought that she had macromastia, a less severe, however, a similar condition. "But when I broke down medical history, the weight loss on Mounjaro and the increased growth and side effects, he was point-blank like, 'This is gigantomastia'," she said.

Moon also told that her breasts currently weight 39 lbs, which is approximately 20 per cent of her overall body weight.

Moon also said that while her large breasts are "normal" at this point in her life, she said the rare condition still comes with challenges.

"The side effects are having numb arms quite a lot and having quite severe indentations on my shoulders. I have some light scarring under my breasts where bras have rubbed and ripped the skin open."

She also said that laying on her back is something she cannot do for a long time, as it restricts the amount of airflow she can get in. She also said that when she goes out she tries to make her breasts look smaller than they are and strap them up. "I [still] get stares and double takes."

Woman Lost Weight On Mounjaro But Her Breasts Didn't Stop Growing: What Is Gigantomastia?

As per Cleveland Clinic, it is a rare condition where your breasts become excessively large. It can also cause pain, infection, discomfort and issues with body image. It is also known as breast hypertrophy where one experiences rapid and disproportionate breast growth. The speed with which the breasts grow could vary depending on the person. It could take a few weeks to over several years. The tissue is almost never benign.

Gigantomastia is characterized by:

• Breasts that have an excess of at least 5 pounds of breast tissue.
• Extra breast tissue that equals more than 3% of your total body weight.

There are different types of gigastomastia:

• Juvenile gigantomastia: This type happens during puberty.
• Gestational gigantomastia: This is when gigantomastia occurs during pregnancy.
• Drug-induced gigantomastia (or medication-induced): This happens after taking certain drugs.
• Idiopathic gigantomastia: This is when the cause of gigantomastia is unknown or can't be determined. Idiopathic gigantomastia is the most common type.

Moon is now considering a breast reduction surgery. She has for now set up an account on OnlyFans. “I might as well try and reap the benefits of my medical condition rather than the negatives," she said.

The recent launch of the indigenous Td vaccine in India by Union Health Minister JP Nadda will boost immunity and reduce the risk of tetanus and diphtheria in children and adults, said health experts.

Union Health Minister JP Nadda formally launched the indigenously manufactured Td vaccine in Himachal Pradesh last week.

With the launch, the Tetanus Toxoid (TT) vaccine has been replaced with the Tetanus and adult diphtheria (Td) vaccine in India’s immunization program for all age groups, including pregnant women.

The move comes amid increasing numbers of cases of diphtheria amongst older age groups. Tetanus and diphtheria can lead to hospitalizations or even cause death. The Td vaccine will help to decrease diphtheria outbreaks.

“In keeping with global practice, India has shifted from TT, which covers for tetanus, to Td, which covers for both tetanus and diphtheria. This vaccine is indigenously manufactured and is expected to significantly reduce the risk of both these diseases in older children as well as adults,” Dr. Rajeev Jayadevan, Ex-President of IMA Cochin and Convener of the Research Cell, Kerala, told HealthandMe.

What Is The Td Vaccine?

The Td vaccine, indigenously manufactured at the Central Research Institute (CRI), Kasauli in Himachal Pradesh, is a combination of tetanus and diphtheria with a lower concentration of diphtheria antigen (d), and is recommended for older children and adults.

The use of Td, instead of TT, is recommended during pregnancy to protect against maternal and neonatal tetanus and diphtheria during prenatal care.

Vaccination during pregnancy also serves to boost immunity and increase the duration of protection in pregnant women who have not received the full set of recommended booster doses.

The Td is a safe vaccine, and 133 countries are currently using it.

The Health Ministry, in a statement, said that the Central Research Institute will supply 55 lakh doses to the UIP by April 2026, with production expected to scale up progressively in subsequent years to further strengthen the Universal Immunization Program in India.

“India’s indigenous Td vaccine rollout marks a significant milestone in strengthening the nation’s immunization program by enhancing self-reliance, affordability, and supply stability,” Dr. Neha Rastogi, Senior Consultant - Infectious Diseases, Fortis Gurugram, told HealthandMe.

“Locally produced vaccines reduce dependency on imports, ensuring uninterrupted protection for adolescents and adults against tetanus and diphtheria. This initiative supports wider coverage, faster distribution to remote regions, and improved public health preparedness,” she added.

Tetanus And Diphtheria: Disease burden In India

As per the National Health Profile 2022, India has reported 1,586 cases and 22 deaths due to diphtheria in 2020, and 3,677 cases and 47 deaths in 2021.

Around 10 Indian states report the majority (84 per cent) of the cases.

As of 21 June 2024, Orissa has also reported six deaths and 21 suspected diphtheria cases. There has been more than 90 percent coverage of diphtheria vaccination in birth cohorts since 2014, but gaps in booster dose coverage are widely prevalent.

Plugging of gaps in the routine immunization, coupled with inclusion of booster doses in the national data on diphtheria vaccination, is the need of the hour.

“Diphtheria is one of the most dangerous infectious diseases known to man; it spreads easily through the respiratory route. It can cause death due to the bacterial toxin affecting the heart (Myocarditis). It is vaccine-preventable, but the immunity fades over time,” Dr. Jayadevan said.

Therefore, the Td booster shots at ages 10 and 16 are essential to maintain protection. Similarly, pregnant women should receive two doses to protect both mother and child.

Given the recent outbreaks of diphtheria in India and elsewhere, this transition is a public health priority, the expert said.
