The treatment process is actually quite convenient for most people with busy lifestyles. Individual sessions for laser nail fungus treatment usually last between thirty to forty-five minutes depending on how many nails need attention. There's no downtime required afterward - you can literally walk out and go back to your normal activities immediately. As for discomfort, most patients report feeling only a slight warming sensation during the procedure, nothing that would be described as painful. The number of sessions needed varies based on the severity of the infection, but typically ranges from three to six treatments spaced a few weeks apart.
