How fast can I make my vocal cord nodule go away?

Vocal cord nodule. Nodules are benign. They are slow to resolve, often taking months. Primary treatment is speech therapy, voice rest and coverage for acid refulx.. Surgery is reserved as the last option if non-surgical treatments aren't successful.
Depends on the cause. Vocal cord nodule may need resection to ascertain the cause of the nodule. Vocal cord nodules can be cancer, viral infection, voice disuse etc. It would be prudent to consult an ENT specialist.
