Psoriasis affects them as they’re forming, which can make it tricky to treat. In some cases, you can use an ointment to take care of a flare-up on your skin, but your nail bed keeps those treatments from sinking in to the problem area.
Instead, your doctor may recommend:
Sometimes it goes away on its own, with no treatment.
Corticosteroid shots
Scraping or filing the nail
Removing the nails
Light therapy
