How do physicians diagnose an ingrown toenail?

The diagnosis of an ingrown toenail is typically straightforward. However, the signs and symptoms of ingrown toenails can vary quite dramatically, particularly if an infection develops. There may simply be some tenderness at the nail border when pressure is applied. There is typically an incurvation of the nail or a spike of nail (spicule) pressing into the skin of the nail border. Associated redness and swelling localized to the nail also suggest the diagnosis of an ingrown toenail. When an infection is involved, there may be severe redness and swelling, drainage, pus, and malodor.

Making the proper diagnosis requires taking into account the medical history and all possible causative factors. If one is unsure, seek professional help. Some conditions such as tumors, foreign bodies, trauma, and fungal infection may appear to be an ingrown toenail to the untrained eye.
