Dont know where you are staying but i have had a lot of experiances with Hospitals in the P.I. The doctors in general are pretty good as in Angeles city the doctor who sent us to hospital also came in and looked after us, but the nurses were woeful. Watch them when they dispense your medicines as they dont always get the dosage right.
The most professional hospital we went to was Makati General in Manilla.
It wasnt myself or my wife that needed the treatment but always our boys when they were young, that just added to the worry.
Moral of the story, try to make it to Manilla.
