For millions of people living with psoriasis, the condition is often thought of as being skin-deep. However, for some, the inflammation that causes skin plaques can also affect the joints, leading to a condition called psoriatic arthritis.

What is Psoriatic Arthritis (PsA)?

Psoriatic arthritis is a type of inflammatory arthritis that affects some people who have psoriasis. It is an autoimmune condition, meaning your immune system mistakenly attacks healthy cells and tissues. This immune response causes inflammation that leads to skin plaques (psoriasis) and joint swelling and pain (arthritis). PsA can develop slowly with mild symptoms, or it can come on quickly and be more severe.

Key Psoriatic Arthritis Symptoms to Watch For

The signs of psoriatic arthritis can vary from person to person. If you have psoriasis, be on the lookout for any of the following symptoms:

• Joint Pain, Stiffness, and Swelling: This is the hallmark symptom. It can affect any joint in the body, but often appears in the fingers, toes, wrists, knees, and ankles. Joints may be warm to the touch.


• Swollen Fingers and Toes (Dactylitis): A characteristic symptom is a painful, sausage-like swelling of an entire finger or toe.


• Morning Stiffness: Feeling particularly stiff and finding it difficult to move your joints when you first wake up.


• Lower Back Pain (Spondylitis): Inflammation can occur in the joints between yourvertebrae or in the joints between your spine and pelvis (sacroiliitis).


• Nail Changes: Many people with PsA see changes in their fingernails and toenails, such as tiny dents (pitting), discoloration, or the nail separating from the nail bed.


• Persistent Fatigue: A debilitating sense of exhaustion that isn't relieved by rest, caused by the body fighting inflammation.

The Diet Connection: What About Dairy and Psoriasis?

You may have heard about a link between dairy and psoriasis. This is a complex topic. Some individuals report that their psoriasis and PsA symptoms flare up after consuming dairy products, possibly due to an inflammatory response. While there is a great deal of anecdotal evidence, large-scale scientific proof is still developing. If you suspect a food trigger, the best approach is to speak with your doctor or a registered dietitian. They may recommend a carefully managed elimination diet to see if it impacts your symptoms.

Protecting Your Joints Starts with a Conversation

The psoriatic arthritis symptoms listed above can significantly impact your quality of life, and if left untreated, the condition can lead to permanent joint damage. The good news is that there are many effective treatments available today. If you have psoriasis and are experiencing any of these signs, don't dismiss them as simple aches and pains. Schedule a consultation with your doctor or a rheumatologist to get an accurate diagnosis and start a treatment plan.
