Introduction
Psoriasis is a common and impactful chronic autoimmune condition and the condition varies in severity, from mild cases with small, localised patches to more severe cases affecting larger areas of the body.
What are Common Symptoms of Psoriasis?
Psoriasis can affect people of any age, sex, or ethnicity and impacts millions of individuals worldwide, affecting approximately 1–3% of the global population. While it can appear at any age, it typically develops between the ages of 15 and 35 or later in life. Most common symptoms are:
Skin plaques or rash: Typically thick, red, and scaly, these patches can appear anywhere on the body but are commonly found on the scalp, elbows, knees, and lower back.
Itchy skin: The itchiness can range from mild to severe and may interfere with sleep.
Cracked, dry skin: Affected areas can crack, sometimes leading to bleeding or infection.
Skin pain: Discomfort or tenderness in the affected areas is a frequent symptom.
Nail changes: Nails may become pitted, cracked and crumbly, discoloured, or even detach from the nail bed.
Joint pain: Psoriatic arthritis can develop in some individuals, causing joint pain, stiffness, and swelling.
Why Does Psoriasis Cause Itching?
Psoriasis is a long-term skin condition characterised by unexpected flare-ups and no known cure. It occurs when the immune system mistakenly attacks healthy cells, triggering inflammation that appears on the skin as red, scaly plaques. The condition causes the immune system to accelerate skin cell production, leading to a build-up of cells that form these patches. This inflammation is the primary cause of itching, which can range from mild to severe.
In addition to the inflammation, various external factors can worsen itching. These include certain types of clothing, stress, weather conditions, and irritants commonly found in soaps, lotions, and other personal care products. Managing these triggers can help reduce discomfort and prevent flare-ups, improving overall quality of life for those with psoriasis.
How Common is Itching in Psoriasis Patients?
Around 70% to 90% of people with psoriasis report experiencing itching, making it one of the most common and disruptive symptoms. This persistent itch can be frustrating and significantly impact daily life, often interfering with sleep, work, and overall well-being.
In addition to itching, individuals with psoriasis may also experience pain and a burning sensation in and around the affected patches. These symptoms can vary in severity, adding to the discomfort and challenges of managing the condition.
Which Factors Affect Itch Severity?
Several factors contribute to the itching associated with psoriasis such as:
Direct causes:
Psoriasis scales and flakiness.
Inflamed skin associated with plaques.
External aggravators:
Clothing that irritates the skin.
Environmental irritants (e.g., soaps, detergents).
Triggers and conditions:
Stress, which can heighten sensitivity and exacerbate symptoms.
Weather conditions:
Dry climates can dehydrate the skin.
Warm climates may increase sweating and irritation.
Unusual itch patterns:
Itching in areas of the body without visible psoriasis plaques.
What is the Impact of Itching on Quality of Life?
Psoriasis does not typically affect life expectancy but can significantly reduce quality of life (QOL). It is often linked to social stigma, a loss of self-confidence, physical discomfort, pain, disability, and psychological distress. Many people with psoriasis report experiencing moderate to severe feelings of anxiety, anger, and depression, underscoring the considerable emotional burden of the condition.
Scratching the affected areas can worsen plaques, increase the risk of infection, and delay healing by irritating the skin and causing wounds. In response, the body increases inflammation to heal the damage, which intensifies the itching and creates a vicious cycle. Breaking this cycle is essential to improving both the physical and emotional well-being of those living with psoriasis.
Management Strategies for Itchy Psoriasis
For many people with psoriasis, itching is one of the most troublesome symptoms. To help manage this discomfort, the following strategies are recommended:
Focus on treating psoriasis: Managing the underlying condition is the most effective way to minimize itching.
Keep showers short: Limit showers to about 5 minutes and baths to 15 minutes or less, as spending too long in water can dry out your skin and aggravate the itch.
Apply moisturiser regularly: Use a moisturising cream or ointment after washing your hands, bathing, or showering to lock in moisture. This can soothe itchiness, reduce redness, and aid skin healing.
Try anti-itch products: Over-the-counter treatments containing ingredients like menthol or camphor can help with itching. Be cautious, as some may irritate or dry the skin, so combining them with a moisturiser is often beneficial.
Moisturise instead of scratching: If you feel the urge to scratch, gently apply a moisturiser to the itchy area instead. This helps calm the itch and prevents further irritation.
Use warm water: Stick to warm water for bathing or showering, as hot water can dry out the skin and make itching worse.
Apply something cool: Placing a cold, damp cloth on the itchy area can provide relief. The cold sensation disrupts the itch signals sent to your brain, helping to reduce discomfort.
When to Seek Medical Attention for Itching
For some people, psoriasis is a mild condition that doesn't interfere much with daily life. However, for others, psoriasis can be much more severe. one should consult a doctor for psoriasis itching if:
1. Itching becomes severe or unbearable: If the itching significantly disrupts your daily activities, sleep, or quality of life, it’s time to seek medical advice.
2. Itching persists despite using treatments: If over-the-counter or prescribed treatments aren't providing relief, or if the itching continues to worsen, a doctor can help adjust your treatment plan.
3. Signs of infection: If the itching leads to scratching that causes broken skin, sores, or signs of infection (such as increased redness, swelling, or pus), you should consult a doctor to prevent complications.
4. Itching spreads to new areas: If the areas affected by itching increase or spread to parts of the body not previously affected by psoriasis, it is worth consulting a healthcare professional.
5. If scratching causes additional skin damage: If frequent scratching results in more irritated skin, open sores, or the development of new psoriasis plaques, it’s important to consult a doctor to address both the itch and the underlying condition.
6. Itching occurs with other symptoms: If itching is accompanied by other concerning symptoms, such as joint pain or significant swelling, it may indicate psoriatic arthritis or another complication, and a doctor can help manage those symptoms.
Conclusion
Itching is a common and troublesome symptom of psoriasis, often leading to discomfort, skin rashes, patches, and an increased risk of infection. While there is no cure for psoriasis, there are various ways to manage the condition and relieve symptoms. Treatment plans are typically tailored to the individual, taking into account factors such as age, the severity of the condition, and overall health.
It is essential to get diagnosed by an expert dermatologist, who can further recommend a personalised combination of treatments, which could include medications, avoiding known triggers, and maintaining a good skincare routine along with a healthy lifestyle.
