Psoriatic Arthritis
An inflammatory arthritis linked to psoriasis that can affect the joints, spine and tendons. Caught early, it is very treatable — protecting the joints while controlling the skin.
What is psoriatic arthritis?
Psoriatic arthritis (PsA) is an inflammatory arthritis that affects some people who have psoriasis — the skin condition that causes red, scaly patches. It can affect the joints, the spine, and the places where tendons attach to bone. Joint symptoms sometimes appear years after the skin changes, and occasionally before them. Early treatment protects the joints and controls both the skin and the arthritis.
Symptoms to recognise
PsA can look different from person to person. Common signs include:
- Painful, swollen joints — sometimes a whole finger or toe swells like a "sausage" (dactylitis)
- Stiffness that is worse in the morning or after rest
- Pain at the heel or the sole of the foot, where tendons attach
- Nail changes — pitting, ridging, or separation from the nail bed
- Lower back or buttock pain if the spine is involved
- A personal or family history of psoriasis
What causes it?
Psoriatic arthritis is driven by an overactive immune system causing inflammation in the joints and skin. It has a strong genetic component and often runs in families. Having psoriasis is the main risk factor, though not everyone with psoriasis develops the arthritis.
When should you see a rheumatologist?
See a rheumatologist if you have psoriasis and develop joint pain, swelling or stiffness, a swollen finger or toe, or persistent heel pain. Because joint damage in PsA can be prevented with early treatment, timely specialist assessment matters — and a rheumatologist can coordinate care for both the joints and the skin.
How it is diagnosed
Diagnosis is based on the combination of skin, nail and joint features:
- Clinical assessment — examining the joints, skin, nails and tendon attachment points
- Imaging — X-rays or ultrasound to assess joint inflammation and detect early changes
- Blood tests — to measure inflammation and help exclude other types of arthritis
How it is treated
Treatment controls inflammation, protects the joints and improves the skin:
- Disease-modifying drugs (DMARDs) — such as methotrexate, which help both joints and skin
- Biologic and targeted therapies — highly effective modern options for more active disease
- Anti-inflammatory medication — to manage pain and stiffness
- Coordinated skin and joint care with regular monitoring
Psoriasis and joint pain together?
That combination deserves a specialist assessment before joints are affected. Consultations are walk-in, no appointment needed.
