Which specialist treats nail psoriasis?

Nail psoriasis may cause pits, ridges, colour change, thickening, crumbling, or lifting from the nail bed. A dermatologist examines the nails and surrounding skin, asks about scalp or body plaques, and checks for tenderness or stiffness that could suggest joint involvement. A sample may be considered when a fungal infection or another cause could look similar. Nail separation is a related concern that deserves assessment rather than self-treatment.

Bring a list of medicines, previous nail treatments, and photographs showing how the changes developed. Keep nails trimmed, avoid picking under a lifted nail, and protect hands from prolonged water or chemical exposure. Treatment depends on how many nails are affected and whether psoriasis is active elsewhere. Options can include medicines applied to the nail, an injection into selected areas, or treatment affecting the wider immune response, such as biologic therapy.

Arrange a dermatology review if a nail change persists, spreads, becomes painful, or interferes with walking or hand use. Seek prompt medical advice for swelling, warmth, pus, fever, or rapidly worsening separation. New finger or toe stiffness, swelling, or pain should also be reported because nail disease can occur alongside psoriatic joint inflammation.

Could this be nail psoriasis, infection, or nail separation? Do I have signs of psoriasis on my skin or scalp? Which treatment fits the number of nails involved? What nail care should I follow while treatment takes effect?
