A lot of doctors and patients believe that if they have an infected ingrown toenail that they can simply take some antibiotics, clear up the infection and they will be fine. Nothing could be further from the truth. The only way to cure an ingrown toenail is to have it removed either by a Podiatrist (highly recommended) or by yourself.
The issue will be if you just use antibiotics the entity causing the infection will still be present and that entity is an ingrown toenail. So the only way to take care of the ingrown so it doesn’t cause the infection is to have it removed.
