Came down with chronic sinusitis and after several visits to the GP visited Dr Ong. He was friendly but you do feel rushed as he's trying to see as many patients as possible in a short period of time the clinic is open in the evenings. First visit, there wasn't much warning and he squirted a numbing spray before the scope, wish there was some warning ahead of time but it happened so fast I was caught off guard. He does explain things a bit and prescribed a strong antibiotic Klacid and Telfast and nasal saline spray. Had a re-occurrence and he suggested after 2 round of antibiotiocs that I have surgery FESS to clear the mucus in the sinuses but I wasn't too thrilled as it would involve nasal packing and having to breathe through my mouth for at least 24 hrs....got a second opinion at a hospital and was told didn't need surgery so deferred surgery but Dr Ong did say it would not be resolved without surgery. Am much better after nasal irrigation and alternative medicine. Glad I didn't opt for the surgery, "minor" or otherwise. It should be the last resort.
