What are the symptoms of psoriasis?
The most common symptoms of psoriasis include:
- red patches of skin
- scaly, sometimes silvery, skin patches
- itchy skin
- joint swelling, stiffness, or pain, which are associated with a condition called psoriatic arthritis
The symptoms of psoriasis also vary based on the type. There are five official types of psoriasis:
- plaque psoriasis
- guttate psoriasis
- inverse psoriasis
- pustular psoriasis
- erythrodermic psoriasis
Psoriasis can also cause symptoms of mental stress, anxiety, and low self-esteem. Depression is also common with people who have psoriasis.
There are also subcategories of different types of psoriasis . These appear differently depending on the location of the body. Psoriasis is not contagious regardless of type.
Plaque psoriasis, or psoriasis vulgaris, is the most common form of psoriasis. An estimated 80 to 90 percent of people with psoriasis have plaque psoriasis. It’s characterized by thick red patches of skin, often with a silver or white scaly layer.
These patches often appear on the:
- lower back
Patches are usually 1 to 10 centimeters wide, but can also be larger and cover more of the body. If you scratch at the scales, the symptoms will often get worse.
Treatments of Plaque psoriasis
As a way to ease discomfort, your doctor may recommend applying moisturizers to keep the skin from becoming too dry or irritated. These moisturizers include an over-the-counter (OTC) cortisone cream or an ointment-based moisturizer.
Your doctor may also work to identify your unique psoriasis triggers, including stress or lack of sleep.
Other treatments may include:
- vitamin D creams, such as calcipotriene (Dovonex) and calcitrol (Rocaltrol) to reduce the rate that skin cells grow
- topical retinoids, to help reduce inflammation
- medication like tazarotene (Tazorac, Avage)
- applications of coal tar, either by cream, oil, or shampoo
- biologics, a category of anti-inflammatory drugs
In some cases, you may need light therapy. This involves exposing the skin to both UVA and UVB rays. Sometimes treatments combine prescription oral medications, light therapies, and prescription ointments to reduce inflammation.
With moderate to severe cases, you may be prescribed systemic medication in the form of oral, injectable, or intravenous medication.
Guttate psoriasis appears in small red spots on the skin. It’s the second most common type, affecting around 8 percent of people with psoriasis. Most of the time it starts during childhood or young adulthood.
The spots are small, separate, and drop-shaped. They often appear on the torso and limbs, but they can also appear on your face and scalp. Spots are usually not as thick as plaque psoriasis, but they can develop into plaque psoriasis over time.
Guttate psoriasis happens after certain triggers. These triggers include:
- strep throat
- skin injury
Flexural or inverse psoriasis often appears in skin-folds, such as under the breasts or in the armpits or groin area. This types of psoriasis is red and often shiny and smooth.
The sweat and moisture from skin-folds keeps this form of psoriasis from shedding skin scales. Sometimes it’s misdiagnosed as a fungal or bacterial infection. The skin-on-skin contact can make inverse psoriasis very uncomfortable.
Most people with inverse psoriasis also have a different form of psoriasis in other places on the body.
The treatments for inverse psoriasis are like plaque psoriasis treatments. They can include:
- topical steroid creams
- light therapy
- oral medications
- biologics, which are available via injection or intravenous infusion
Pustular psoriasis is a severe form of psoriasis. It develops fast in the form of many white pustules surrounded by red skin.
Pustular psoriasis may affect isolated areas of the body, like the hands and feet, or cover most of the skin’s surface. These pustules can also join together and form scaling.
Some people experience cyclic periods of pustules and remission. While the pus is noninfectious, this condition can cause flu-like symptoms such as:
- rapid pulse
- muscle weakness
- loss of appetite
There are three kinds of pustular psoriasis:
- von Zumbusch
- palmoplantar pustulosis (PPP)
Each of the three forms of pustular psoriasis can have different symptoms and severity.
Treatment may include OTC or prescription corticosteroid creams, oral medications, or light therapy. Biologics may be recommended as well.
Identifying and treating the underlying cause may also help reduce reoccurrence of pustular psoriasis.
Erythrodermic psoriasis, or exfoliative psoriasis, is a rare psoriasis type that looks like severe burns. The condition is serious, and can be a medical emergency. You may need hospitalization because your body may not be able to control body temperature.
This form of psoriasis is widespread, red, and scaly. It may cover large portions of the body. Exfoliation often occurs in larger pieces than the small scales typical to most psoriasis.
Erythrodermic psoriasis can develop from:
- pustular psoriasis
- widespread, poorly controlled plaque psoriasis
- a bad sunburn
- significant stress
- abrupt discontinuation of a systemic psoriasis medicine
A person with this condition often needs hospital attention. At the hospital, you’ll receive a combination of therapies.
This can include an application of medicated wet dressings, topical steroid applications, biologics, or prescription oral medications until symptoms have improved.
Make an appointment with your doctor if you think you have erythrodermic psoriasis.
Psoriatic arthritis (PsA) is a painful and physically limiting condition that affects between 30 and 33 percent of people with psoriasis. There are five types of PsA with varying symptoms. There is also no cure for this condition.
Because psoriasis is an autoimmune disease, it can trigger the body to attack the joints and the skin. It can affect many joints and often becomes quite severe in the hands. Skin symptoms usually appear before joint symptoms.
Treatments for psoriatic arthritis can include nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil) and naproxen sodium (Aleve). NSAIDs can help reduce the incidences of swelling and pain associated with psoriatic arthritis.
Prescription medications, such as prednisone, an oral corticosteroid, may also help to reduce inflammation that leads to psoriatic arthritis. Prescription topical medications used to treat psoriatic arthritis include salicylic acid, calciopotriene, and tazarotene.
Light therapy may also help reduce symptoms.
A unique category of medications known as disease-modifying antirheumatic drugs (DMARDs) can help reduce inflammation and joint damage. Biologics, which are a subcategory of DMARDs, may be prescribed to reduce inflammation at a cellular level.
Although not an official types of psoriasis, nail psoriasis is a manifestation of psoriasis. The condition can often be confused with fungal infections and other infections of the nail.
Nail psoriasis can cause:
- nail pitting
- loosening or crumbling of the nail
- thickened skin under the nail
- colored patches or spots under the nail
Sometimes the nail can even crumble and fall off. There is no cure for psoriatic nails, but some treatments may improve the health and appearance of nails.
Treatments for nail psoriasis are like the ones used for plaque psoriasis. It may take time to see the effects of these treatments as nails grow very slowly. Treatment options include:
- light therapy
- oral medications, such as methotrexate
Scalp psoriasis is common in people with plaque psoriasis. For some people, it may cause severe dandruff. For others, it can be painful, itchy, and very noticeable at the hairline. Scalp psoriasis can extend to the neck, face, and ears in one large patch or many smaller patches.
In some cases, scalp psoriasis can complicate regular hair hygiene. Excessive scratching can cause hair loss and scalp infections. The condition may also cause feelings of social stress.
- medicated shampoos
- steroid-containing lotions
- tar preparations
- topical application of vitamin D, known as calcipotriene (Dovonex)
Light therapy, oral medications, and biologics also may be recommended depending upon the responsiveness to treatment.
Self-care for psoriasis
- practicing relaxation techniques to reduce stress
- moisturizing dry skin
- quitting smoking
- avoiding products that irritate your skin
- wearing comfortable clothing that doesn’t rub the psoriasis
- eating a healthy diet.
Coping and support
Stress, anxiety, depression, and other mental health disorders can be side effects of psoriasis. You may benefit from therapy or support groups where you can meet other people experiencing similar issues or concerns.
You can also talk with your healthcare provider about seeing a therapist who has experience with psoriasis. They’ll be able to help identify ways to cope.
