What is nail psoriasis, and how can I treat it?
If you have psoriasis, it’s important to check your fingernails and toenails for signs of nail psoriasis. Common signs include:
- Tiny dents in your nails (called “nail pits”)
- White, yellow, or brown discoloration
- Crumbling nails
- Nail(s) separating from your finger or toe
- Buildup beneath your nail
- Blood under your nail
If you notice any of these signs or another problem with a nail, tell your dermatologist. Treatment can help clear nail psoriasis and reduce pain. Without treatment, nail psoriasis may worsen. Some people develop “disappearing” nails. This can affect people’s ability to use their hands or walk. Treatment can prevent this.
Nail changes can also be a sign of psoriatic arthritis, so you want to see your dermatologist to find out. Treating psoriatic arthritis can prevent it from getting worse.
