Nail Problems

Nail problems can be localised to the nails or as part of a general medical condition. Some nail conditions give a clue to the underlying medical problem. Skin rash that affects the skin can also affect the nails. Some nail problems include nail inflammation, benign and malignant skin growths, cyst and infection

Nail infection

The nails can be infected by virus, bacterial or fungus.  Fungal nail infection is common and affects both finger and toe nails, leaving the nail plate brittle, thickened or completely destroyed. Virus can cause warts on the nail bed and the nail fold.

Treatment of nail infection

  • Good hygiene and proper nail care
  • Nail matrix biopsy
  • Culture for bacteria and fungi
  • Topical or oral antibiotic and antifungal
  • Laser treatment
  • Cryosurgery
  • Viral warts are treated by cryotherapy or laser or topical immunotherapy
