About Muscle Tension Dysphonia
If your voice is tired, your throat feels tight, or it hurts to talk, you may have muscle tension dysphonia, or voice strain. This common voice problem can occur even if your vocal cords are normal, but the muscles in your throat are working inefficiently. You may not have enough breath to support your voice, or your throat muscles may be too tight when you speak. Muscle tension dysphonia can make your voice sound strained and feel uncomfortable when you talk.
Muscle tension dysphonia can happen when you’ve been sick and developed an injury to the vocal cords, such as laryngitis or swelling of the vocal cords. Because of that injury, you may start relying on other muscles in your throat to force your voice out. Even when your vocal cords have healed after the illness is over, you can get stuck in a pattern of muscle strain.
Other factors that may contribute to muscle tension dysphonia include excessive talking without breaks, screaming, talking loudly in noisy environments, or habitually speaking at a pitch that is too high or too low for you.
