Foul Smell
Nail fungus would lead to some dying or dead tissues under these areas. As a result, a foul smell might occur when these components accumulate. The symptom can also be caused by nail separation. You can easily notice this odor as it is quite similar to that of something decaying or dead. While an unpleasant smell does not always indicate the presence of a fungal infection, detecting this can help you find out any health issue early and get proper treatment. [2]
