What causes fainting, for those of us who have ET? I am concerned and am looking for clarification, in order to better understand what’s behind it and if there are triggers. Also, I have suffered from several incidents of vasovagal syncope, which causes fainting. I don’t understand how to differentiate the differences between ET fainting and vasovagal syncope – and desperately need to know. I would appreciate any information you can share to help me cope with this.
