He has seen an ENT specialist. They've looked with a camera and noted that the vocal chords just aren't moving. There's nothing else obvious on them though they are slightly swollen.
He has a sort of dalek-like voice which he manages to achieve by-passing the normal chords if that makes sense.
This is now the third time he's had it. The first time it lasted about 4/5 months and he was 10. He had it last year aged 11 and it was worse and went on for longer (6 months). Now he's got it again and it has been about a month so far.
We have no idea what brings it on or why it just suddenly sorts itself out.
I should mention he has T1 diabetes. Not sure if it's connected but AS IF HE HASN'T ALREADY GOT ENOUGH TO DEAL WITH!!
