Healthcare is ok.
You can choose from public clinics where most of the doctors are Indian. Some are excellent and some should be locked up - like the spastic who wanted to conduct exploratory spinal surgery on me after me having torn a muscle.
The Armed Forces Hospital is great. Very nice Irish lady in charge of ER there who really looked after me.
Muscat Private Hospital has European and US doctors and also Australians and maybe Kayways
Our unit deal directly with Muscat Private but remember that the ambulance service here is "sectoral" so they will take you to the nearest hospital. This is how I ended up with the mad scientist doctor and is what worries me sometimes, especially if I was unconscious.
All in all though, the system here is excellent - if you get the right hospital.
