Understanding Skin Lesions: Common Causes and Symptoms
Skin lesions, also known as skin abnormalities or dermatological conditions, can occur for various reasons and may present as different types of abnormalities on the skin’s surface. These lesions can range from mild to severe and may cause discomfort or distress to those affected. In this article, we will explore some of the common causes and symptoms of skin lesions to help you better understand these conditions and seek appropriate medical attention when needed.
One of the most common causes of skin lesions is infection. Various types of bacteria, viruses, fungi, and parasites can infect the skin, leading to the formation of lesions. For example, bacterial infections like impetigo can cause red, crusted sores that may be itchy and contagious. Viral infections like herpes simplex virus can cause painful, fluid-filled blisters on or around the lips or genital area. Fungal infections like ringworm can cause circular, scaly patches on the skin, while parasitic infections like scabies can cause itchy, raised bumps or burrows on the skin.
Inflammation of the skin can also lead to the development of skin lesions. Conditions like eczema (atopic dermatitis) can cause red, itchy, and scaly patches on the skin that may ooze or crust. Psoriasis is another chronic inflammatory skin condition that causes thick, silvery scales on the skin’s surface, often accompanied by itching and discomfort. Contact dermatitis, which occurs when the skin comes into contact with irritants or allergens, can cause redness, rash, and blisters on the affected area.
Autoimmune conditions, where the body’s immune system attacks its own cells, can also cause skin lesions. For example, lupus is an autoimmune disease that can affect the skin and cause a variety of lesions, including a butterfly-shaped rash on the face, discoid lupus, which presents as circular scaly patches on the skin, or vasculitis, which causes inflamed blood vessels in the skin resulting in painful, tender nodules or ulcers.
lesions can also be caused by neoplastic conditions, which involve the abnormal growth of cells. Skin cancer is a common type of neoplastic condition that can cause various types of lesions, including a raised bump or nodule that may bleed, a changing mole or birthmark, or a non-healing sore on the skin. Cancer can be caused by various factors, including exposure to ultraviolet radiation from the sun or tanning beds, genetic predisposition, and immune system suppression.
Some skin lesions can be caused by genetic factors. For example, genetic disorders like neurofibromatosis can cause multiple benign tumors (neurofibromas) to form on or under the skin. These tumors can appear as soft, fleshy nodules or bumps that may vary in size and number. Another genetic condition called xeroderma pigmentosum can cause the skin to be extremely sensitive to sunlight, leading to the development of skin lesions and an increased risk of skin cancer.
Trauma to the skin can also result in skin lesions. Burns, cuts, abrasions, and other injuries to the skin can cause various types of lesions, including blisters, scars, and open sores. These lesions may heal over time, but they can leave lasting marks on the skin, depending on the severity of the trauma.
Symptoms of Skin Lesions:
The symptoms of skin lesions can vary depending on the underlying cause. Common symptoms associated with skin lesions may include:
Redness, rash, or discoloration of the skin it.

What is the mysterious “sleep paralysis “and what science says about why it occurs
The first time it happened to me, I was just a teenager.
What is the mysterious “sleep paralysis “and what science says about why it occurs
I still had a few hours to go before I had to get up for school when I woke up. I tried to turn in bed, but my body wouldn’t allow it, I couldn’t move, I was paralyzed up to my toes.
Although my brain was conscious, my muscles were still asleep.
My room felt hot and restrictive, like the walls were closing in, and I panicked. Finally, after about 15 seconds, the paralysis disappeared.
Later, I found a name for what had happened to me: sleep paralysis.
This is a surprisingly common nocturnal condition in which part of the brain wakes up while the body remains temporarily paralyzed.
After that first – and terrifying – incident, I experienced sleep paralysis frequently, with one episode every two or three nights.
The more that happened, the less scary it became. Eventually, it was little more than an inconvenience.
But sleep paralysis can affect people’s lives.
For some, it comes with disturbing hallucinations.
A 24-year-old woman I spoke to, who asked to be identified only by her first name, Victoria, recalls having her first experience one night when she was just 18 years old.
“I woke up and I couldn’t move,” he told me.
“I saw this gremlin-like figure hiding behind my curtain. It jumped on my chest. I thought I had entered another dimension. And the scariest thing was that I couldn’t scream. It was so vivid, so real.”
Researchers believe that these hallucinations may have fueled belief in witches in modern Europe, and could even explain some claims of alien abductions.
What is known about the phenomenon?
Scientists believe that sleep paralysis has probably been around for as long as humans slept.
There are various colorful descriptions of these episodes throughout literary history.
Mary Shelley, the British playwright best known for authoring the gothic novel Frankenstein, was inspired by a painting depicting an episode of sleep paralysis to write a scene for the play.
But the truth is that, until now, little research has been done on this rare condition.
“It’s been an ignored phenomenon… but in the last 10 years there’s been increasing interest,” says Baland Jalal, a sleep researcher at Harvard University, who in 2020 completed the first clinical trial on different ways to treat paralysis. of the dream
Lucid dreaming: what are the best techniques to control your dreams, according to science
Jalal is one of the few sleep scientists to spend time and energy researching the condition.
His goal is to more solidly understand the causes and effects of this and to discover what it tells us about the broader mysteries of the human brain.
But in 2011, clinical psychologist Brian Sharpless, currently an associate professor at St Mary’s College of Maryland, conducted the most comprehensive review to date of the prevalence of the condition in people.
It examined data from 35 studies spanning five decades. Together, they included more than 36,000 volunteers.
Sharpless found that sleep paralysis was more common than previously thought, with almost 8% of adults claiming to have experienced it at some point. That number is much higher among college students (28%) and psychiatric patients (32%).
“It’s not that uncommon,” says Sharpless, who is also a co-author of “Sleep Paralysis: Historical, Psychological, and Medical Perspectives.”
How is it explained?
After experiencing the phenomenon, some people try to understand what happened to them with supernatural or even paranormal explanations.
In reality, says Jalal, the cause is much more mundane.
At night, our body goes through four stages of sleep. The final stage is called Rapid Eye Movement or REM sleep. This is when we dream.
During REM, your brain paralyzes your muscles, probably to prevent you from acting out physically in your dreams and getting hurt. But sometimes, and scientists are still not sure why, the sensory part of the brain emerges from REM prematurely.
“The sensory part of the brain is activated,” says Jalal. “You’re waking up mentally, perceptually, but physically you’re still paralyzed,” he adds.
When I was in my early twenties, I would experience sleep paralysis every two or three nights, but even then, it didn’t have much of an impact on my life. It was an interesting anecdote for friends and family. In that sense, my experience was common.
“For most people, it’s a peculiar thing that they live with,” says Colin Espie, professor of sleep medicine at the University of Oxford.
“It’s a bit like sleepwalking: most people who sleepwalk never see a doctor. It’s a curiosity in the family, a topic of conversation.”
But for an unfortunate minority, the condition is not so anecdotal.
Anxiety and anguish
Sharpless’s research found that between 15% and 44% of people with sleep paralysis experience “clinically significant distress” as a result.
The problems usually stem from how we respond to sleep paralysis, rather than the condition itself. Patients obsess all day about when the next episode might occur.
“It can be anxiety-inducing at the beginning and end of the night,” says Espie.
“And you grow a web of worry and restlessness around you. The worst expression of that is a kind of panic attack.”
Doctors assert that sleep deprivation increases the likelihood of experiencing paralysis because it fragments sleep architecture. Some patients report that lying on their back increases the chances of paralysis, although the reason for this remains unclear.
To treat sleep paralysis, the most prevalent approach involves educating patients by teaching them about the science behind the condition and providing reassurance that they are not in any danger.
Sometimes a form of meditation therapy is used. The goal is to reduce the patient’s anxiety about going to bed and train them to remain calm when sleep paralysis occurs.
In more severe cases, doctors may consider prescribing medications, including selective serotonin reuptake inhibitors (SSRIs). SSRIs are usually used to treat depression, but they have the side effect of suppressing REM sleep.
The most dramatic and memorable episodes of sleep paralysis are usually the ones that come with vivid hallucinations.
These night visions are often a source of fear, but scientists also believe they can tell us fascinating things about the human brain.
But the muscles are paralyzed, so the brain doesn’t get any feedback signals in return.
“There is an incongruity… the self is fragmented, degraded,” says Jalal.
As a result, the brain “fills in the gap” and creates an explanation for why the muscles can’t move. That’s why so many hallucinations involve a creature sitting on your chest or holding your body.
The brain, a “story-telling machine”
This reinforces the idea, popular among evolutionary scientists, of the human brain as a “story-telling machine.”
We struggle to come to terms with the fact that much of the world is random, so our brains create dramatic narratives to find meaning in the mundane.
Christopher French, head of the anomalous psychology research unit at Goldsmiths, University of London, has spent more than a decade talking to people around the world who have experienced these hallucinations and recording what they saw.
“There are common themes, but there’s also a lot of idiosyncrasies, variability,” French says.
Why do we need more hours of sleep in winter than in summer?
Some hallucinations are hard to explain, and even downright bizarre. Over the years, the French have recorded sightings of a sinister-looking black cat and a man strangled by plants.
Culture heavily influences other behaviors that are much more common.
On the island of Newfoundland in Canada, it is common for people to see an “old hag” sitting on their chests.
Mexicans, meanwhile, usually hallucinate with a “dead man” lying on their chest, while those from Saint Lucia speak of “korma”, the souls of unbaptized children. And the Turks imagine the “Karabasan”, a mysterious and ghostly creature.
This reinforces the idea that humans are overwhelmingly social animals, heavily influenced by culture and expectations.
In fact, in a series of studies, Jalal compared symptoms in Denmark and Egypt, among volunteers with a similar age and gender distribution, and found a cultural gulf in the way sleep paralysis manifested itself.
Egyptians were much more likely than Danes to have experienced sleep paralysis ( 44% compared to 25% ), and more likely to support a supernatural explanation.
“When you have anxiety and stress, your sleep architecture becomes more fragmented, so you’re more likely to have sleep paralysis,” he says.
Your grandmother’s description of the creature, which appears at night and attacks, causes hyper-arousal in you and hyper-alertness in the fear centers of your brain. And during REM sleep you feel, ‘oh, something’s wrong, I can’t move, the creature is here'”.
“It seems that culture can create this amazing effect,” he concludes.
