What are Nodules?
Vocal nodules or nodes are non-cancerous growths on the vocal folds (cords) caused by vocal abuse. The nodules are small and callous-like and appear as symmetric swellings on either side of the vocal folds The nodules usually form on the areas of the vocal cords that receive the most pressure when the cords come together to produce sound. Size can vary from a tiny pinpoint to a pea.
