han19, when I suggested one the best paediatric nephrology surgeon in India to look at Qatar as his next career move and how he can lead a very relaxed life while making a lot of money, his answer was, "I don't want to lose the precision of my probe".
Honestly, I can understand the trauma of this father, as I have been at similar crossroad myself. As far as medications are concerned, it is absolutely fine to continue with the best ENT specialist available (two names you have suggested might be really good) but when it comes to matters as serious as surgery, well, you must know where to look.
