About a year ago my mother had arrived at the ER with severe abdominal pain and vomitting. She was sent home three times because where she lived, in a shelter. She was told she was just coming there for free food and a place to stay. My mother was finally diagnosed on the fourth time via a CAT scan with a severe blood clot that caused for immediate surgery. Her blood clot was so big it required 2/3 of her intestine to be removed. She is now living with a colostomy bag and lives only due to a TPN through an IV. She is at the University of Pittsburgh awaiting a small bowel transplant. I believe her misdiagnose may have led to her blood clot becoming bigger and causing the intestine to be removed. Is this enough for a medical malpractice case?
