If your toenail looks yellow, thick, brittle, or has white spots, it could be nail fungus—especially since you’ve had it for 2 years and already have a history of nail fungus.

Possible Causes:
Nail Fungus (Onychomycosis) – Common in damaged nails and worsened by moisture.
Nail Polish Staining – Dark polish can leave yellow stains, but this usually fades over time.
Nail Weakness or Damage – Long-term polish use can make nails brittle or flaky.
What to Do:
Try antifungal treatment – OTC creams or medicated polishes can help.
Give your nails a break – Avoid polish for a few weeks and keep them clean.
See a doctor – If the nail is thick, lifting, or spreading to other toes, you may need prescription treatment.
