Nail fungus infection is usually caused by fungal organisms that grow under or around the nail and often leads to thick, brittle, discoloured, or damaged nails. These infections can take several months to improve because nails grow slowly. Doctors commonly prescribe antifungal nail paints, creams, or oral antifungal tablets depending on how severe the infection is and how many nails are affected. Keep the nails clean and dry, trim them regularly, and avoid tight footwear or prolonged moisture around the feet or hands. Do not share nail cutters, socks, shoes, or towels with others because fungal infections can spread easily. Avoid using steroid-containing creams without medical advice, as they may worsen the infection or delay proper treatment. Please consult a dermatologist for proper examination because some nail problems may resemble fungal infection, but may have other causes like psoriasis or nail injury. Seek medical care if you develop pain, swelling, pus, or difficulty walking due to the infected nail.
