#AskTheExpert Dear sir. I am asking for my 5 year old son. From last one year, he was having some kind of hoarseness in his voice. He used to shout a lot. Now I have shown him to a doctor nearby and he advised me to go for one endoscopy. But sir, I know the difficulty in taking endoscopy especially for a child. So is it required to go for that? Is it a matter of that much concern? He is now under voice rest and the sound has improved also. Please guide sir so that I can do the needful.
