Vocal cord nodules are symmetric, benign protrusions that occur on the free edge of the vocal cords. Clinically, the main symptoms of vocal cord nodules include a hoarse voice and fatigue after prolonged speaking, typically without any sensation of pain or causing any pain. Treatment primarily involves medication, voice therapy, and for some vocal cord nodules that appear after an acute upper respiratory infection, hormonal treatment may be required, or combined with some antibiotics. In summary, vocal cord nodules do not cause painful symptoms, and treatment focuses mainly on voice training and rest for the vocal cords.
