My sister in law broke her arm in 3 places. They put her in a cast and put her in a sling. She kept telling them her shoulder hurt. Doctor ended up getting pissed off, calling her av drug seeker and kicking her out of the hospital.
After a month she went to a specialist and was like "yeah my arm feels fine but my shoulder hurts really bad." Doctor did xrays, immediately requested the xrays from the hospital and had her come back in.
He showed her on the most recent xrays how her arm was very clearly outside of it's socket. He showed her the previous xrays from the hospital where it was the same. Then he read her the notes where one doctor commented on it that it was out of the socket and dislocated and needed to be fixed. But the doctor she had wrote notes ONLY about the broken arm and specifically said everything else looked normal. Clearly not reading the other doctors notes.
Unfortunately due to some other health circumstances and how long it had been, they could not do anything to get her arm back in the shoulder. She permanently lost all ability to use that arm for the rest of her life. The specialist said "I never tell people this but, if I were you, I would absolutely get a lawyer."
She did. She won. That was also a fiasco. Their lawyer wasn't very good. Followed me around for months. Presented evidence that she was totally fine with picture and videos of me. The judge was not amused. My SIL was 30 years older than me, a foot shorter and about 70 pounds less. Zero chance you could confuse us.
Her and my brother bought a house, a car, and a truck with that money. Which got them out of poverty.
