I would go to a Dr. Chen, has a small chinese clinic, think it is the corner of HuaMei west street / ZhongCheng street. Would say between Fingas BaseCamp and sogo, close to the "riverside".
That guy can fix many things, and he has good english skills as well.
Not really shure if it's opposite The Dive, but at least it will be close. Found their name card though, It should be on HuaMei west street section 1, #33. Have a green looking sign with the NHI logo on it I think.
