What is Psoriatic Arthritis?
Psoriatic arthritis is a chronic inflammatory form of arthritis that affects some people who have psoriasis, a skin condition characterized by red patches covered with silvery scales.
In most cases, psoriasis develops years before joint symptoms appear. However, in some individuals, joint pain and stiffness may begin before skin changes or occur at the same time.
The condition causes joint pain, stiffness, and swelling, which can affect any part of the body, including the fingertips and spine. Disease severity can range from mild to severe, with periods of flare-ups alternating with phases of remission.
Although there is no cure for psoriatic arthritis, early diagnosis and appropriate treatment are essential to control symptoms and prevent long-term joint damage and disability.
Symptoms of Psoriatic Arthritis
Psoriatic arthritis is a progressive condition, but symptoms may improve or temporarily disappear during periods of remission.
The disease can affect joints on one or both sides of the body. While symptoms may resemble those of rheumatoid arthritis, psoriatic arthritis has several distinctive features.
- Painful, swollen, and warm joints
- Swollen fingers and toes with a sausage-like appearance (dactylitis)
- Foot pain, especially at the heel (Achilles tendinitis) or sole (plantar fasciitis)
- Lower back pain due to spinal inflammation (spondylitis or sacroiliitis)
- Nail changes such as pitting, crumbling, or separation from the nail bed
- Eye inflammation (uveitis), causing redness, pain, and blurred vision
Causes of Psoriatic Arthritis
Psoriatic arthritis develops when the immune system mistakenly attacks healthy cells and tissues, leading to inflammation in the joints and excessive production of skin cells.
Both genetic and environmental factors contribute to the development of the disease. Many individuals with psoriatic arthritis have a family history of psoriasis or psoriatic arthritis.
Environmental triggers such as physical trauma, viral infections, or bacterial infections may initiate the disease in genetically predisposed individuals.
Risk Factors
Several factors may increase the likelihood of developing psoriatic arthritis, including:
- Presence of psoriasis, which is the strongest risk factor
- Family history of psoriasis or psoriatic arthritis
- Age – most commonly affects adults between 30 and 55 years
Why Early Specialist Care Matters
Psoriatic arthritis can progressively damage joints if left untreated. Early evaluation by a rheumatologist allows timely diagnosis, effective symptom control, and prevention of irreversible joint damage.
Specialist care focuses on reducing inflammation, preserving joint function, and improving overall quality of life through personalized treatment strategies.
