What happens?

The exact cause of PsA is unknown. In most cases the arthritis develops after the appearance of psoriasis. Many people will find that their joints are stiff first thing in the morning or after resting.

PsA can be difficult to diagnose because you may have similar symptoms to people with other forms of arthritis.

How will it affect me?

Psoriatic arthritis can affect most joints. You may have:

  • pitting and discoloration of nails
  • spondylitis – a stiff, painful back or neck caused by inflammation in the spine
  • iritis – inflammation around the pupil of the eye
  • swollen and sore joints at the end of fingers or toes
  • constant tiredness and the need to rest

How is it treated?

Your doctor might prescribe you:

Ointments are the main form of skin treatments, but you may also need tablet treatment and light therapy (shining ultraviolet light on your skin).

What you can do

There are several ways in which you can manage your condition:

  • exercise to maintain muscle strength and mobility
  • rest your joints – learning some relaxation techniques can help
