Clubbing of the fingers or toes

Clubbing is changes in the areas under and around the toenails and fingernails that occur with some disorders. The nails also show changes.

Common symptoms of clubbing:

  • The nail beds soften. The nails may seem to "float" instead of being firmly attached.
  • The nails forms a sharper angle with the cuticle.
