HI . My Name Is Tracey .Im 46 Years Old

HI . My name is Tracey .Im 46 years old and never had a seizure before. Buy on sunday while getting into my car I bumped my knee. It hurt but not the worst pain I have felt. Almost straightaway I felt a hot flash run through my body then I felt like I was going to be sick. Next thing I know. My husband was talking to me from what seemed far away but was right next to me. He said I went real stiff and fell against the window. Jerking my breathing was strange he said I even snorted. My eyes were open but I was staring straight ahead . During the seizure I remember having racing thoughts. I cant remember what they were about. Just remember my thoughts were fast and strange. Is this normal and what was it.I do have an appointment with my family doctor in a few days
