What should you know about skin symptoms of psoriatic arthritis?

Psoriatic arthritis is an inflammatory joint condition associated with psoriasis. Skin changes may include well-defined, scaly patches, often on the scalp, elbows, knees, or behind the ears. Nail pitting, separation, or thickening can also occur. Skin severity does not reliably show how active joint inflammation is: some people develop joint symptoms before obvious skin changes. [Psoriatic Arthritis](/conditions/psoriatic-arthritis/) can affect fingers, toes, the spine, or tendon attachments.

Record when skin flares and joint symptoms begin, and note morning stiffness, swollen digits, heel pain, or reduced movement. Arrange assessment with a clinician familiar with inflammatory arthritis. Treatment may combine skin care, [Anti-Inflammatory Medication](/treatments/non-surgical-orthopedics/anti-inflammatory-medication/), and [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) to protect movement and strength. Do not stop prescribed medicine because the skin looks better.

Seek prompt medical advice for a newly swollen joint, persistent [Joint Pain](/symptoms/joint-pain/), or [Morning Joint Stiffness](/symptoms/morning-joint-stiffness/) that limits activity. Urgent help is appropriate for a hot, very painful joint with fever, sudden loss of function, or a painful red eye with vision change. A new rash alone is not proof of psoriatic arthritis, but it deserves review if joint symptoms accompany it.

Ask whether your skin or nail findings fit psoriasis, whether swollen joints need imaging or blood tests, and which treatment plan protects both skin and joint function.
