What is an ingrown toenail?
An ingrown toenail is defined as a nail growing directly into your skin. When it gets more severe, the nail will pierce the skin and create an infection. The skin around the ingrown toenail will be red, swollen and quite painful to touch.
What causes ingrown toenails?
A nail shape can genetically have a tendency to curve in, hereby creating an ingrown toenail with time. Also, tight shoes create more compression around the nail, causing with time the nail to curve inside in order to grow away from the compression forces.
Cutting can also be a factor. It is important to know that when you try to dig inside the side of your nail to cut the corner out, the nail changes shape. By repetitively cutting your nail short, you are putting yourself at risk of creating an ingrown toenail.
Nails also respond poorly to excessive friction. Aside from tight shoes, if you have a tendency to have sweaty feet, it increases the friction around your toenail.
