​Psoriasis is linked closely with psoriatic arthritis although having one doesn’t guarantee you will suffer with both. A high percentage of people who present with psoriatic arthritis have also suffered with psoriasis of the skin. Risk of depression is also increased by psoriasis. ​
What is psoriatic arthritis and how is it related to normal psoriasis?
Psoriatic arthritis is a disease which affects the joints, resulting in pain, inflammation and stiffness. It is more common in people over 30 and people who suffer with psoriasis of the skin are notably more likely to develop it - psoriatic arthritis is often preceded by psoriasis of the skin. However, having one form of psoriasis does not automatically guarantee that you will have the other. Untreated psoriatic arthritis can result in progressive joint damage. 
The symptoms of psoriatic arthritis
Psoriatic arthritis can present very quickly and severely or be a gradual process presenting with mild symptoms - it depends entirely on the individual. If you experience symptoms you should consult a doctor. The common symptoms are as follows: 
  • Joint pain 
  • Inflammation/swelling of the joints 
  • Stiffness in the joints 

Early diagnosis and treatment is recommended to prevent a worsening of symptoms. If you are concerned that you might have psoriatic arthritis you should discuss this with your doctor.
