Accordingly, ingrown nail has been divided into the following three stages [20] :

  • Stage 1: Mild erythema edema and pain with pressure

  • Stage 2: Significant erythema, edema, local infection, and discharge

  • Stage 3: Granulation tissue formation and hypertrophy of the lateral wall besides the significant erythema, edema, and discharge (see image below)
