Nails infected with fungus can be discolored, thick, brittle, crumbly, or misshapen. Some examples of nail fungus are included here. However, it’s
important to keep in mind that other things can cause nails to look bad. Trauma to the nail is most often the culprit
and can occur through stubbing, dropping a heavy object on the toe, and microtrauma caused by running, hiking, or participating in other sports activities.
In addition, psoriasis and eczema can also cause pitting and other problems with the nails.
