The infection usually causes a small white, yellow-brown or green spot to appear on a particular area of the nail, but if left untreated, it tends to spread to affect a larger portion of the nail. The affected nail will become thicker and may crumble or fall off, causing pain and discomfort. At this point, the fungus may also spread to affect other nails.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_82_2 counter-hierarchy ez-toc-counter ez-toc-custom ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Indice<\/p>\n<span class=\"ez-toc-title-toggle\"><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/dermaclub.it\/en\/dermatology-fact-sheets\/fungal-nail-infection-onychomycosis\/#Description\" >Description<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/dermaclub.it\/en\/dermatology-fact-sheets\/fungal-nail-infection-onychomycosis\/#Causes\" >Causes<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/dermaclub.it\/en\/dermatology-fact-sheets\/fungal-nail-infection-onychomycosis\/#Symptoms\" >Symptoms<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/dermaclub.it\/en\/dermatology-fact-sheets\/fungal-nail-infection-onychomycosis\/#Diagnosis\" >Diagnosis<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/dermaclub.it\/en\/dermatology-fact-sheets\/fungal-nail-infection-onychomycosis\/#Treatment\" >Treatment<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/dermaclub.it\/en\/dermatology-fact-sheets\/fungal-nail-infection-onychomycosis\/#Prevention\" >Prevention<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Description\"><\/span><b>Description<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>[\/vc_column_text][vc_column_text]Toenails are more frequently affected by fungi than fingernails because socks and shoes provide the warm, moist environment that fungi need to grow and spread.
