Injury: Trauma and some illnesses can do this. Remember that nails are related to hair but grow more slowly so that an injury to them may show up over time.
I often see this in my oncology patient with certain chemotherapy. They well have lines in the nails.

It depends: Changes in fingernails can be indicative of an underlying medical disorder. Ridges or bumps can be related to iron deficiency. Anemia, lupus, heart disease, and thyroid disorders can also can changes to the fingernails. Fungal infection also can cause bumps and discoloration of the nailbed.
