Vocal nodules are small, callous-like growths that form on the vocal cords due to excessive or improper use of the voice. They often develop in individuals who frequently strain their voices, such as singers, teachers, or public speakers. Symptoms may include hoarseness, a raspy voice, and difficulty hitting high notes. Treatment for vocal nodules typically involves voice therapy, where a speech-language pathologist helps individuals learn proper vocal techniques. In some cases, surgery may be necessary to remove the nodules. Preventive measures include staying hydrated and avoiding yelling or speaking loudly for extended periods.
