Can I sue a doctor who treated me during an emergency without my history?
I fainted and fell from the bus. I was full term pregnant when this happened. I was lying on the ground crying in pain when a person who claimed to be a doctor came and helped me. He called an ambulance. In the ambulance, I starting having contractions and was in pain. This doctor gave me some medicine, which did not suit me. Although I delivered, the same day and we are fine but it could have been a threat to my child. Can I sue this doctor for giving me medicine without knowing my medical history?
