Your vocal folds are tiny muscles that deal with highly pressurised air and vibrate at extreme speeds to create sound. The brain always aims for safe and efficient vocal technique but when this isn't the case a variety of vocal injuries can occur.
A Vocal nodule is a hard callous-like growth on the vocal folds created by incorrect vocal technique (Usually excess pressure when the vocal folds come together or the vocal folds not closing completely in between vibrations.) Vocal nodules can result in raspy or hoarse vocal qualities, diminished pitch range and breathy voice.
Similar to nodules; Polyps are caused by incorrect vocal technique and cause raspy or hoarse vocal qualities, diminished pitch range and breathy voice. However, polyps present as soft growths.
Vocal fold paralysis
When one or both of the vocal folds do not coordinate when opening or closing this is called Vocal fold paralysis and can lead to a weaker voice, breath inefficiency, swallowing issues and coughing.
The above vocal injuries can be fixed through a combination of surgery, rehabilitation, rest and technique correction. If you are experiencing any of the above issues it is recommended that you visit a specialist such as MVAC.
As a singer you can avoid vocal fatigue and injury in many ways.
1) Always warm up thoroughly.
2) Do not push through discomfort or pain.
3) Don't attempt new skills without a vocal coach.
4) Always warm down your voice.
5) If your voice doesn't feel healthy rest by avoiding speaking and not participating in any singing.
6) After an intense vocal workout steam and rest your voice.
