What is muscle tension dysphonia?
Muscle tension dysphonia (MTD) is caused by muscles in and around the larynx (“voice box”) that are overactive. This abnormal tension can occur as a reaction to an underlying condition or on its own. MTD can cause hoarseness, decreased vocal flexibility, increased vocal fatigue, increased vocal effort, and discomfort/pain in your throat. In some instances, it can feel like something is stuck in your throat and may make swallowing difficult.
