The signs and symptoms of?psoriasis?vary depending on the person and type of psoriasis.
Common symptoms of psoriasis include:
- Plaques — raised, inflamed patches of skin covered with scale (the buildup of dead skin cells). On white skin, plaques typically appear red with silvery-white scale, while on skin of color plaques may be purple, gray, or dark brown
- Small, round, scaly spots (common in children with psoriasis)
- Dry, cracked skin that may bleed
- Itching, burning, or soreness
- Thickened, pitted, or ridged nails
- Swollen and stiff joints
Psoriasis patches can range from a few spots of dandruff-like scaling to major eruptions that cover large areas.
Most types of psoriasis go through cycles, flaring for a few weeks or months, then subsiding for a time or even going into complete remission.
What Are the Signs and Symptoms of Plaque Psoriasis?
If you have plaque psoriasis, one of the most common symptoms is raised, inflamed patches of skin that are covered with scale. These patches are known as plaques. The following are signs that you may have plaque psoriasis:
- Raised, inflamed skin patches that can appear anywhere on the body
- A scaly coating on skin patches
- Frequent locations for patches include the knees, elbows, lower back, and?scalp
- Patches that thicken when scratched
- Patches varying in size, either alone or joined together
- Nails that are pitted, crumbling, or falling off
6 Psoriatic Arthritis Symptoms You Shouldn't Ignore
What Are the Signs and Symptoms of Guttate Psoriasis?
This type of psoriasis may clear up without any treatment, but it sometimes requires medical attention. It may appear for a single episode, typically following an illness like strep throat, or it may signal the start of plaque psoriasis.
Symptoms of guttate psoriasis include:
- Small spots that are most common on the trunk, arms, and legs, but can show up anywhere on the body
- Spots that clear up in a few weeks or months without treatment
What Are the Signs and Symptoms of Pustular Psoriasis?
- Discolored, swollen, and dotted skin with pus-filled bumps
- Bumps, often only on the palms and soles
- Sore, painful bumps
- Discolored dots or scale on the skin after pus-filled bumps dry
When pus-filled bumps cover the body, you may have inflamed skin and feel ill, exhausted, have a fever, chills, severe itching, rapid pulse, loss of appetite, or muscle weakness.
What Are the Signs and Symptoms of Inverse Psoriasis?
Inverse psoriasis occurs in 21 to 30 percent of people with psoriasis, usually alongside some other form of the condition. It can be one of the most painful and irritating forms of the disease.
The symptoms of inverse psoriasis include:
- Smooth, discolored patches of skin — on skin of color these may appear purplish, brown, or darker than the surrounding skin, while on white skin these lesions may be bright red and shiny
- Sore skin
- Patches only on creases of the skin, like the armpits, near the groin, genitals, and buttocks
- Raw patches under the fold of the breast
What Are the Signs and Symptoms of Erythrodermic Psoriasis?
- Skin that looks burned
- Bright red or otherwise discolored skin over much of the body
- Feeling very hot or very cold
- Rapid heartbeat
- Intense itching
- Severe pain
How Is Psoriasis Diagnosed?
Most of the time, your physician can diagnose psoriasis by taking your medical history and examining your skin, scalp, and nails.
In some cases, a skin biopsy may be done to determine the type of psoriasis, and to rule out other disorders that look similar to psoriasis, such as?dyshidrotic eczema, seborrheic dermatitis, lichen planus,?ringworm, and pityriasis rosea.
Can Psoriasis Lead to Other Health Complications?
Your skin plays a vital role in regulating body temperature, providing hydration, and protecting against infection.
When skin disorders such as?psoriasis?affect the body, certain changes take place that may lead to additional problems.
Doctors aren’t sure if the risk of developing other conditions is solely related to the disease itself or if psoriasis treatment also plays a role.
People with psoriatic arthritis experience painful, swollen joints and other symptoms.
You can develop psoriatic arthritis any time, but it most commonly appears between age 30 and 50.
Psoriasis and psoriatic arthritis can increase your risk of developing the following health problems:
Cancer?In one recent meta-analysis, researchers found an association between psoriasis and an increased risk of developing cancers, including colon and liver.
