An ingrown toenail occurs when the edge of a toenail grows into the surrounding skin, causing pain, redness, and swelling. It typically affects the big toe and can result from improper nail trimming, tight footwear, or injury. Infected ingrown toenails can lead to more serious complications if left untreated.
To avoid ingrown toenails, trim your toenails straight across rather than rounding the corners, and avoid cutting them too short. Wear properly fitting shoes that provide enough room for your toes. Keep your feet clean and dry, and avoid injury to your toenails. If you have recurring issues, consider seeking advice from a healthcare professional.
