"The pits
When the normally smooth surface of the fingernail has several small dents or pits in it, that can be a signal that something is going on beneath the nail. Most often, the cause of those dents is psoriasis. The inflammatory skin conditionâit shows up as red, scaly patches on the skinâcan also affect the skin cells in the nails. Instead of growing out smoothly, the surface of the nail takes on a dented appearance. Once the psoriasis is treated and under control, nails will slowly return to normal. (Since nails only grow about a millimeter per week, it will take a few months for the old, pitted nail to fully grow out and be replaced with a healthy one.)"
But I don't have any hint of psoriasis.
