Medical care is quite safe here in Doha. Unlike what skdkak said, its not just common cold and stuff alone that are treated here. There are close to a million people here who are treated in Hamad. Also HMC is JCI accredited and my personal experience here has been good. I have seen many europeans and americans getting treatment here, Most of teh docs are trained in good centres around the world.

You could always have a second opinion though from a doc you know or from UK. By the way I know how the NHS works, Doha is far better.
