You'll know you're getting nail psoriasis when you see these changes in your fingernails or toenails:
Color. Your nails may turn green, yellow, or brown. They may also have small red or white spots underneath.
Surface appearance. You may get ridges or grooves in your nails, or pitting (small pinprick holes) on the nail surface.
Debris buildup. Chalky white material can gather under your nail, causing it to lift away from the skin. This can be painful.
Thickening. About a third of people with nail psoriasis can also get a fungal infection that can cause your nails to get thick. They may also get brittle and break.
Separation. Your nail may loosen or separate from the nail bed.
Some of these nail changes can make it hard to move your fingers and toes. You may also get tenderness and pain in your nails. This can make it hard to do things with your hands.
Prevent Nail Problems
Good nail care is the best way to treat nail psoriasis. Try these tips:
Keep your nails trimmed short.
Use a nail file to keep nail edges smooth.
Wear gloves to clean and do other work with your hands.
Moisturize your nails and cuticles every day and after they've been in contact with water.
Wear comfortable shoes with enough room for your toes.
If you're unhappy with the way your nails look, try nail varnish or artificial nails. They can also protect your nails from more damage. Some people are sensitive to the chemicals in varnish and nail adhesive. Talk to your doctor about whether these are right for you.
Treatments for Nail Psoriasis
The same treatments you get for skin psoriasis can also treat your nail psoriasis. Because your nails grow slowly, it can take time before you see any improvements in the newly grown parts of your nail.
