Can Psoriasis Affect Nails and Joints?
Many people think of psoriasis as a skin condition that causes red, scaly patches. However, psoriasis can affect much more than the skin. In some individuals, it can involve the nails and even the joints, leading to symptoms that impact daily activities and quality of life.
Understanding these lesser-known effects of psoriasis is important because early diagnosis and treatment may help reduce discomfort and prevent long-term complications.

What Is Psoriasis?
Psoriasis is a chronic inflammatory condition that causes skin cells to multiply faster than normal. This leads to thickened, red, and scaly patches that commonly appear on the scalp, elbows, knees, and lower back.
Although psoriasis primarily affects the skin, the same inflammatory process can also impact the nails and joints in certain individuals.
Can Psoriasis Affect the Nails?
Yes. Nail psoriasis is a common manifestation of psoriasis and may occur even when skin symptoms are mild. In some cases, nail changes may be one of the earliest signs of the condition.
Psoriasis can affect both fingernails and toenails, leading to changes in appearance, texture, and nail growth.
Nail Pitting
Small dents or pits on the nail surface.
Thickening
Nails may become thicker and harder.
Discolouration
Yellow, brown, or white changes may develop.
Nail Separation
The nail may lift away from the nail bed.
Can Psoriasis Affect the Joints?
Yes. Some people with psoriasis may develop a condition known as Psoriatic Arthritis (PsA), an inflammatory form of arthritis associated with psoriasis.
Psoriatic arthritis can affect various joints throughout the body and may range from mild discomfort to more significant joint inflammation if left untreated.
Common Symptoms of Psoriatic Arthritis
- Joint pain and tenderness
- Morning stiffness
- Swollen fingers or toes
- Reduced joint flexibility
- Fatigue associated with inflammation
