I highly recommend Dr Gan Tong Nee (ENT Specialist @ Sunway Medical Centre) for those who are suffering from sinus infection, stuffy nose or sinus headaches. He is very friendly and professional in his field.
I had my FESS surgery by Dr Gan Tong Nee last week. The procedure takes about an hour, and it does not hurt at all. The result was amazing and I can breathe so much better than before.

I have suffered from sinusitis for years, and I was taking all kind of medicine like Panadol, Zyrtec D, Clarinase and antihistamine etc.
I would recommend taking FESS surgery that solves all sinus problem, comparing to taking all kinds of medication that works for only sometime.
