The big toe is the most common location for ingrown toenails. An ingrown toenail occurs when the edge of a toenail grows into the soft surrounding skin. This causes swelling, redness, and pain. If the nail is allowed to continue growing this way, more discomfort occurs.
Prompt care is needed because the cut can easily become infected.
These infections can be especially dangerous in people, such as diabetics, who have poor circulation. Improperly trimmed toenails and tight shoes cause ingrown toenails. Always cut toenails straight across, leaving them a little longer at the corners. This ensures that the toenails will grow over the top of the skin, not under it. Use nail clippers to make neat cuts.
