They could be caused by damage to the nail bed. Over enthusiastic pushing back of cuticles etc. The bed is damaged at that point and probably will never grow out. They can also occur if you have had a severe illness.
If you feel ok and healthy just ignore this. If the nails get very much worse then see a dermatologist, but I think the damage has been done and its like a scar in the nail bed.
Thank you for help. Well I don’t push cuticles or anything just use creams for hands and nails and I never had any kind of accident with nails. I’m suspicious because it is now on all of my nails on both hands.
Ivana…you are obviously concerned so do see your doctor or dermatologist. Theres only so much help that can be offered on this site.
