What should you know about green nail fungus?

Green colour may develop when a nail lifts from its bed and stays damp. Bacteria can grow in that space, while fungal infection may cause thickening, crumbling, separation, or yellow-white colour. The two problems can coexist, and appearance alone cannot reliably identify the cause. Discoloured Nails describes the visible symptom; Nail Fungus explains the fungal condition in more detail.

A nearby Athlete's Foot infection can provide a source of fungal spread to toenails. Nail trauma, tight footwear, nail cosmetics, and repeated water exposure can also change the nail environment.

Keep the nail clean and dry, trim it straight across, and avoid digging beneath it. Pause polish or artificial nails so the surface can be observed. Do not share clippers, towels, or footwear, and disinfect tools after use. A clinician may examine scrapings or clippings before selecting treatment, because antibacterial and antifungal medicines are not interchangeable.

Options can include Topical Antifungal Treatment, Oral Antifungal Treatment, or Laser Treatment For Nail Fungus when fungus is confirmed and the person is suitable. Nail Surgery is reserved for selected problems such as a painful or severely damaged nail, not as a routine answer to colour alone.

Arrange review if the colour persists, spreads, or is joined by pain, swelling, drainage, a foul smell, thickening, or nail separation. Seek prompt care for redness spreading into the surrounding skin, fever, or severe tenderness. People with diabetes, poor circulation, or reduced immunity should arrange assessment early for a foot or nail change.

Could this be bacterial, fungal, trauma-related, or something else? Do I need a nail sample? Should I treat Athlete's Foot at the same time? Which medicines fit my health history, and how will we monitor the nail as it grows?
