### What Are Ingrown Nails? Ingrown nails occur when your nail grows into the skin instead of over it. This is more common with toenails, especially the big toe. ### Symptoms When a nail starts growing into the skin, you may experience pain, redness, and swelling. If the ingrown nail gets infected, symptoms can worsen, including increased pain, pus, and more swelling. ### Prevention Proper grooming is key to preventing ingrown nails. Cut your nails straight across and avoid cutting them too short. Wear shoes that fit well and provide enough room for your toes. ### Home Treatment If your ingrown nail isn't infected, you can treat it at home. Soak your foot in warm water several times a day to reduce swelling and pain. Gently lift the nail and place a small piece of cotton or dental floss under it to help it grow above the skin. ### When to See a Doctor If your symptoms don't improve with home treatment or if they worsen, see a doctor. You should also seek medical attention if you have diabetes, vascular problems, or numbness in your toes, as these conditions can complicate an ingrown nail. ### Complications Untreated ingrown nails can lead to severe complications, including infection, increased pain, and permanent changes in the tissue around the nail.
