I had uncompleted one, and was in the same situation. The longer you leave it the bigger risk of infection. And then again if you for a proceure under full anesthetic you risk that overkeen doc or senior nurse will "poke" you too much. In the end, I decided to go for a pill. Painful process overnight with not much sleep, but cost HKD80 vs HKD 20,000 going for a procedure. Makes big difference if you have no insurance.
