Hi, I am a 39 year old woman and work as a nurse. 5 days ago, while at work, I had what they said was a vasovagal attack which lasted for almost an hour but I did not pass out. I felt dizzi, weak, slow pulse, dettatch from the environment, could hardly walk or talk. It was very scary. All the tests they did were ok. % days later now, I still feel exhausted and have no energy. I also feel a bit breathless at times. Can you help please?
