My voice has been giving me problems since the first years of touring, because we used to do really extensive tours and sometimes even matinees as well, on the same day. Can you imagine me doing a matinee? I ended up getting noduels, uncouth calluses growing in my thorat, and from time to time they harmed my vocal dexterity.
It’s misuing the voice that does it, and once you get nodules, they are always there, and they always come back.
