Be sure to see your doctor if you notice any unusual symptoms that you haven't had before.
Notable symptoms are:
- Lines on the nail;
- Color changes;
- Small cysts with cuticles;
- White or black stripes;
- Change in the shape of the nail;
- The nail has thickened or thinned;
- Brittle nails;
- Bleeding around the nail;
- A kind of floral effect, cut out;
- Swelling or redness around the nail;
- Pain
- Nail lifting up.
