Psoriatic Disease: A Guide for Patients and Caregivers
What is Psoriatic Disease?

If you’re here, you may be living with psoriasis, psoriatic arthritis, or symptoms that don’t yet have a name. You might also be supporting someone you care about.
Psoriatic Disease UK exists to help you understand what’s happening in your body, what support is available, and how to live well with psoriatic disease — whether you’re at the very start of your journey or further along.
You are not alone.
What is psoriatic disease?
Psoriatic disease is an umbrella term used to describe related long‑term conditions that affect the immune system and cause inflammation in the body.
The two main conditions are:
Psoriasis – a condition that mainly affects the skin
Psoriatic arthritis – a form of inflammatory arthritis that affects joints, tendons, and ligaments
Some people have only psoriasis, some have only psoriatic arthritis, and many have both.
Psoriatic disease is not contagious and is not caused by anything you did.
Psoriasis: the skin condition
Psoriasis is a long‑term inflammatory skin condition.
It commonly causes:
Red, inflamed patches of skin
Silvery or white scales (note, on darker skin, psoriasis typically appears as dark brown, purple, or grayish plaques rather than the bright red patches often seen on lighter skin)
Skin that may itch, crack, or feel sore
Psoriasis can affect any part of the body, including:
Elbows and knees
Scalp
Lower back
Nails
Face, hands, or feet
Genitals
Symptoms can vary widely. Some people have mild patches; others find psoriasis has a significant impact on daily life, confidence, and wellbeing.
Psoriatic arthritis: the joint condition
Psoriatic arthritis is an inflammatory arthritis linked to psoriasis. It can develop before or after skin symptoms, or sometimes when psoriasis is very mild.
It may cause:
Joint pain, stiffness, or swelling
Stiffness that is worse in the morning or after rest
Pain in tendons or ligaments (for example, around the heel or elbow)
Swollen fingers or toes (“sausage digits”)
Fatigue
Early diagnosis and treatment are important, as untreated inflammation can lead to permanent joint damage.
Why early recognition matters
Psoriatic disease is a whole‑body condition, not just a skin or joint problem.
Getting the right support early can:
Reduce symptoms
Help protect joints and mobility
Improve quality of life
Support mental and emotional wellbeing
If you think your symptoms could be linked to psoriasis or psoriatic arthritis, it’s important to speak to your GP.
How psoriatic disease is treated
There is currently no cure, but there are effective treatments that help control symptoms and inflammation.
Treatment may include:
Creams and ointments for the skin
Tablets that reduce inflammation
Injectable or infusion treatments (often called biologics)
Pain relief and anti‑inflammatory medicines
Physiotherapy or podiatry support
Treatment plans are individual and may change over time.
Living with psoriatic disease
Psoriatic disease can affect more than physical health. Many people experience:
Fatigue
Changes in mood or confidence
Impact on work, relationships, and social life
Support, information, and understanding make a real difference — both for people with the condition and for those around them.
Information for family, friends, and supporters
If you support someone with psoriatic disease:
Symptoms may fluctuate — good days and bad days are common
Pain and fatigue are not always visible
Emotional support and understanding are just as important as practical help
Learning about the condition can help you support your loved one more confidently.
