My first memory after leaving the house to cycle was being taken by the ambulance to the hospital. I was evaluated by several medical professionals. One of them spent two hours stitching my mouth and forehead back into something that resembles a human being.
Brazilian SUS is not perfect by any means. It's unorganized and some procedures and operations can take a long time to happen. There's lots of corruption with doctors that work in multiple places at the same time.
But, a lot of the time, it freaking works. The paramedics were gentle, affectionate, and competent. Some in the street knew my mother so they when to my house and called her--she accompanied me in the ambulance.
The hospital was not pretty by any standard. There were burn victims screaming bloody hell and I'm pretty sure I saw a woman die--but hey, that's a hospital, people die there!
An actual orthopedist made sure I did not have any fracture. An actual neurologist made sure I have no neural damage. A surgeon stitched my mouth and forehead back together into something that doesn't look like a character out of Frankenstein. It still looks bad, but it'll improve with time. A very nice nurse cleaned up all my bruises and have me aftercare orientations.
On several occasions, we had to manually seek people and procedures that were supposed to happen automatically. The operation itself was a mess, but the doctors and nurses were extremely caring, competent, and dedicated.
This all cost me exactly zero dollars. I didn't even had to fulfill any absurd form or provide an excess of documentation: just my national registry (RG), something almost every citizen has unless they're a very specific kind of homeless.
This is in a very poor unstable country. It is absolutely not perfect, but on many occasions, it kinda works!
