Some people’s nails are normally more rounded than others, which increases the chance of developing ingrown toenail. Cause migh be: naturally short nails, obesity, diabetes, toenail infections, fungal nail disease, prior nail surgery, abnormal nail growths, arthritis, and excessive foot sweating.
If the nail isn’t infected, one of the most common and effective home remedies is to take a cotton ball or some waxed dental floss and place it under the nail. Skin may be swollen, firm, red, or tender to touch. At times, there may be a small amount of pus present. Nails that are rounded rather than cut straight across can also cause the nail to break the soft skin.
