Ingrown toe nail
An ingrown toenail develops when the sides of the toenail grow into the surrounding skin. The nail curls and pierces the skin, which becomes red, swollen and tender.
The big toe is often affected, either on one or both sides. Other possible symptoms include:
pain if pressure is placed on the toe
inflammation of the skin at the end of the toe
a build-up of fluid in the area surrounding the toe
an overgrowth of skin around the affected toe
white or yellow pus coming from the affected area

Ingrowing toenails can be treatable, however the severity of the ingrown toe nail needs to be observed prior to treatment.
