"When health is absent, wisdom cannot reveal itself, art cannot manifest, strength cannot fight, wealth becomes useless, and intelligence cannot be applied."
~Herophilus (335–280 BC), Alexandrian physician
When I need tests or specialists not available in my primary care clinic, I go to The Medical City. Mainly because they're covered by our medical insurance and it's not too far from where I live and work. Thankfully, all my experiences with their doctors, and hospital and laboratory staff have all been good. But then, I haven't had anything serious and I've only had to stay overnight once.
Knock on wood.
