Vocal cord nodules are small, benign growths that develop on the vocal cords due to overuse or strain. They often occur in individuals who use their voice frequently, such as teachers, singers, or public speakers. These nodules can cause hoarseness, a raspy voice, and difficulty in vocal range. Treatment typically involves voice therapy to reduce strain and improve vocal technique. In some cases, surgery may be necessary if the nodules do not respond to therapy. Preventive measures include proper vocal warm-ups and hydration to maintain healthy vocal cords.
