An ingrown toenail occurs when the edges of the nail grow into the skin.
This is most commonly seen in the big toe, although it can occur on any nail, and can be quite painful and sometimes lead to infection. There are many things that can cause an ingrown nail including poor nail trimming, wrongly fitted shoes or trauma. Conservative treatment is used initially and usually effective, however sometimes minor surgical intervention is needed for reoccurring or severe ingrown nails.
