Voice damaged from screaming

Does anyone have any experience of their child damaging their vocal chords/ voice box from screaming? I am about to take my child to the docs to ask if its possible because his voice has gone raspy and he's getting sore throats (not from a cold etc.). On the plus side the noise level has gone down ;-), but I am worried he's doing permanent damage. Any knowledge or experience of this would be greatly appreciated.

  • I work in a music department with vocal tutors, yes this is possible. Worst case scenario is your child could get nodules, not good for singing but wouldn't effect anyone else significantly.
