A fungal infection of the nail, especially when the nail looks damaged or dead, usually needs antifungal treatment. Your doctor may recommend topical antifungal creams or medicated nail solutions, and in some cases, oral antifungal medicines if the infection is severe. Treatment can take several weeks to months, as nails grow slowly. Keep your nails clean and dry, avoid sharing nail tools, and follow proper hygiene to prevent the infection from coming back. Regular follow-up with your doctor is important to ensure the infection is fully treated.

If your nails are causing severe discomfort, it could be due to infection, fungal disease, injury, or underlying health issues. It is important to consult a dermatologist or doctor promptly to identify the cause and start appropriate treatment.
