Psoriatic Arthritis is a type of inflammatory arthritis that commonly affects people with psoriasis. It is a chronic autoimmune disease that causes joint inflammation and subsequent pain, stiffness, and swelling. The immune system attacks itself, the body’s joints, skin, and organs.
Psoriasis is an autoimmune disease in which the body rapidly multiplies skin cells. The skin cells build-up and form itchy, scaly plaques on the knees, elbow, trunk, and scalp.
Psoriatic arthritis affects 3 in 10 people who have psoriasis. For many people it develops 10 years after psoriasis appears. It can, however, affect people who don’t have psoriasis.
Psoriatic arthritis affects men and women equally. It usually develops after 30 but may begin in childhood. Children who develop psoriatic arthritis are at risk of developing uveitis (inflammation of the middle layer of the eye).
The exact cause behind psoriatic arthritis is not fully understood however, we understand it stems from an exaggerated immune system response. The biggest risk factor for developing psoriatic arthritis is genetics. In fact, it was found that, in people who had psoriatic arthritis, 40% had a family member with psoriasis or arthritis. It is also believed that environmental triggers such as an infection, stress, trauma or a virus may play a role in the pathogenesis of psoriatic arthritis.
Psoriatic arthritis symptoms, severity and number of joints affected, vary person to person. Symptoms can come and go, with triggers catalysing a flare up. Psoriatic arthritis affects mainly the large joints of the lower limb, the small joints of the fingers and toes, the spine and sacroiliac joints of the pelvis. Psoriatic arthritis also affects the eyes, tendons, gastrointestinal tract and nails.
Research has shown that prolonged persistent inflammation from psoriatic arthritis causes joint damage so early intervention is integral in reducing disability. Unfortunately, there is no cure for psoriatic arthritis however, there are treatments available to slow disease progression, lessen pain, protect joint integrity, and preserve joint mobility.
It is important to work with a rheumatologist (a doctor who specialises in the treatment of arthritis) to find the right treatment plan for you.
There are different types of psoriatic arthritis which all vary depending on which joints of the body are affected. The importance of sub-classifying psoriatic arthritis means that diagnostic conclusions can be drawn faster, and individualised treatment can be started earlier. The different types of psoriatic arthritis include:
Asymmetric arthritis occurs in 35% of people with the psoriatic arthritis. The joints affected by asymmetric arthritis occur on one side of the body. Asymmetric psoriatic arthritis affects no more than 5 joints. Asymmetric arthritis often precedes symmetrical polyarthritis.
Symmetrical polyarthritis is similar to rheumatoid arthritis, as affected joints are mirrored on both sides of the body (e.g. left and right elbow). Symmetrical polyarthritis affects 5 or more joints on both sides of the body and is more disabling than asymmetric arthritis. This is the most common type of psoriatic arthritis and is present in 50% of people with psoriatic arthritis.
Distal interphalangeal arthritis affects the small joints of the fingers and/or toes. We know that psoriatic arthritis doesn’t just affect the joints, it also affects other organs like the skin and nails. In distal interphalangeal arthritis, nail symptoms of spotting, pitting, or separating from the nail bed are prevalent. Less than 20% of people with psoriatic arthritis have this type of arthritis in isolation, it often occurs with other sub types of psoriatic arthritis.
Spondylitis is a type of psoriatic arthritis that affects the joints of the spine. The cervical spine (neck), lumbar supine (lower back) and sacroiliac joints (pelvic joints) are the most affected. If left untreated the joints can fuse together cause great stiffness and pain. This sub type occurs in 20% of people with psoriatic arthritis.
The rarest and most severe form of psoriatic arthritis is arthritis mutilans. It affects less than 5% of people with psoriatic arthritis. In this sub type, bone is reabsorbed, and joints are dissolved by the body. Joints become stiff and immobile as they fuse together (ankyloses). This results in the shortening of the fingers, and the skin folds in on itself. This unique appearance is described as an “opera glass hand” or “telescope finger.”
Psoriatic arthritis can present differently person to person. Below are the most common symptoms of psoriatic arthritis:
Treatments for psoriatic arthritis vary depending on sub type and severity. Psoriatic arthritis can be managed conservatively with medications, lifestyle changes, exercise, topical treatments, physiotherapy and assistive devices, or non-conservatively through surgery.
Let’s start by addressing natural remedies and therapies for psoriatic arthritis treatment. When psoriatic arthritis isn’t majorly disabling or worsening, implementing lifestyle changes can make a difference in your symptoms. Natural remedies to psoriatic arthritis include:
When deciding on topical ointments and creams for psoriatic arthritis treatment, you need to decide what symptoms you are looking to treat. The reason we say this is because people can have psoriatic arthritis without having psoriasis. If you have psoriatic arthritis and skin psoriasis, it is integral that you manage both. Good news is, for some cases, both can be managed with topical treatments.
For joint pain and swelling we recommend any topical ointment high in magnesium.
Magnesium's pain relief effect is due to being able to block a particular pain receptor known as NMDA. These receptors are located in the skin and the spinal cord and are responsible for communicating the sensation of pain to the brain. That’s why topical magnesium is so good for reducing pain, because the receptors responsible for pain communication are in the skin. It also bypasses the gastrointestinal tract (no laxative effect) and is fast acting!

There are many medications for treatment of psoriatic arthritis. However, psoriatic arthritis is a complex disease, so seeking professional advice from a rheumatologist is integral finding individualised, effective psoriatic arthritis treatment. The following medications are currently prescribed to manage psoriatic arthritis.
If you have read this and are thinking, I think I have psoriatic arthritis… go and see a doctor as soon as possible. We know that psoriatic arthritis can cause permanent, disabling joint damage if not treated early. In addition to stopping joint damage, treating psoriatic arthritis will reduce your systemic inflammation and reduce your risk of developing other inflammatory diseases.
Psoriatic arthritis is not an isolated physical disease. Our social and mental paradigms are usually negatively impacted as well. Gaining adequate treatment for the physical symptoms of psoriatic arthritis helps reduce daily discomfort but seeking help from a mental health professional or psoriatic arthritis support group is also important in managing the disease holistically. The two groups we recommend are the National Psoriasis Foundation (NPF) and Overcoming Psoriasis community group on facebook. The NPF has resources, community groups and social support for people living with the disease. Overcoming Psoriasis focuses on sharing personal experiences of living with the disease- from diagnosis, to symptoms, to treatments, no stone is left unturned.
