My son has this condition with his fingernails. At first I thought he was biting down on them leaving them wavy. I took him to a dermatologist for another problem he was having. When he spotted his fingernails he told me that eventually he will probably have issues with psoriasis. See below. So far, no issues that I am aware of, but something to keep in the back of your mind for later.
Psoriasis - Symptoms
The classic symptoms of psoriasis are raised, red patches of skin topped with loose, silvery scales, usually on the knees or elbows.
There are several types of psoriasis. Symptoms for each type may vary in severity and appear in a wide array of combinations. In general, the major symptoms of psoriasis include:
Bright red areas of raised patches (plaques) on the skin, often covered with loose, silvery scales. Plaques can occur anywhere, but commonly they occur on the knees, elbows, scalp, hands, feet, or lower back. Nearly 90% of people with psoriasis have plaque-type psoriasis.1
Tiny areas of bleeding when skin scales are picked or scraped off (Auspitz's sign).
Mild scaling to thick, crusted plaques on the scalp.
Itching, especially during sudden flare-ups or when the psoriasis patches are in body folds, such as under the breasts or buttocks.
Nail disorders. Nail disorders are common, especially in severe psoriasis. Nail symptoms include:
Tiny pits in the nails (not found with fungal nail infections).
Yellowish discoloration of the toenails and sometimes the fingernails.
Separation of the end of the nail from the nail bed.
Less often, a buildup of skin debris under the nails
