I had an MRI done yesterday. While explaining what was going to happen, they said that it was going to be the same as last time, including the contrast injection. I told them that I didn't have the injection last time. And the girl went and looked up my info and said that yes, I did have it. And I was like, I would know if you gave me an injection because I bruise badly bc I have bad veins. So then I asked my grandma if they gave me an injection bc she was in the room when I had the MRI and she said, no why? So I explain the whole thing to her, and she agreed that I def. did NOT have that injection. So, I call the MRI place back, and they are continuously telling me that I am wrong and that I did have it, so just drop the issue. I feel very angry, and the worst part is, they won't even re-do the test to make sure!! I wish there was something that I could do to fight this, but my gram says there really isn't anything that I can do. But, I say there is. So, I need to find some sort of legal advice bc this is really bothering me to the point that I can't even fall asleep. It's constantly on my mind!!
