Oh, that’s horrible. I had had foot surgery and the surgeon put a steel rod in my foot. A few days later the pain was awful,so I went to the emergency room. They did an X-ray and said the rod was working its way out. They sent the X-ray to the surgeon and he told me nothing was wrong, it was in my head. So I went to a different hospital ER and the doctor there told me the same thing. He then started to shout at me for using resources when he found out I’d already gone to one ER. I calmly explained that the surgeon wouldn’t do anything and I was getting a second opinion. Then he got on the phone demanding to talk to the Dr who operated and yelled at him. I had remedial surgery the next day. Not the same as cancer but yeah you have to demand respect and treatment sometimes.
