This is another tactic in the elimination of nail fungus infections that medical professionals are still unsure about. However, let’s point out a few general facts regarding nail fungus cases and whether it’s possible that removing a nail is a real way to cure toenail fungus. How to know which treatment to use often depends on the stage of the infection and other factors. If there is only a white patch on the nail, a strong, effective topical nail fungus treatment should cure the infection. If there is nail thickening, brittleness, separation and inflammation, topical solutions are still effective but there may need to be an oral supplement of some kind to increase the medicinal dosage. The usual discoloration of the toenail is a yellowish brown hue. If there are other organisms causing the change in the toenail, the discoloration may take on a dark green to black appearance. Black toenail can also be caused by trauma, autoimmune disorders, and melanoma. If the infected nail is in this advanced condition, it is very important to consult a medical professional to determine the proper course of action. It is obviously very important to arrive at the right diagnosis before treatment or sufferers will simply be wasting their time and money.
