Common questions about psoriasis and psoriatic arthritis

Category Filter

  • Can psoriasis cause joint pain?

    Yes. Around 1 in 3 people with psoriasis may develop psoriatic arthritis, which can cause joint pain, stiffness, swelling and fatigue.

    Early recognition of symptoms is important, as prompt diagnosis and treatment can help reduce inflammation and protect joint health.

  • What are the early signs of psoriatic arthritis?

    Early signs of psoriatic arthritis can include joint pain, stiffness (particularly in the morning), swelling of fingers or toes, and pain where tendons or ligaments attach to bone.

    Some people may also experience fatigue, reduced flexibility or nail changes alongside their joint symptoms.

    Symptoms vary from person to person and may develop gradually over time.

    Recognising the signs early and seeking medical advice can help support timely diagnosis and treatment.

  • Can stress cause a flare-up?

    Yes. Stress is a common trigger for psoriasis flare-ups in some people and may also contribute to worsening symptoms of psoriatic arthritis.

    Living with a long-term condition can itself be stressful, which can sometimes create a cycle of stress and symptom flare-ups.

    Managing stress through relaxation techniques, exercise, support networks or other wellbeing strategies may help some people reduce the impact of symptoms, although it will not cure the condition.

    See Psychological aspects of psoriasis for more information.

  • How does the sun affect psoriasis?

    Many people find that moderate exposure to sunlight can help improve psoriasis symptoms, as ultraviolet (UV) light may slow the rapid growth of skin cells. However, too much sun can cause sunburn, which may trigger a psoriasis flare-up and increase the risk of skin damage.

  • What are emollients and how can they help psoriasis?

    Emollients are moisturising treatments that help keep the skin hydrated, reduce dryness and scaling, and support the skin's natural barrier. Regular use of emollients is an important part of psoriasis care and may help improve comfort, reduce itching and enhance the effectiveness of other treatments.
