For a couple of months now I have been blacking out not to the point where I pass out I can still hear I just cant see and everything gets muffled. It has been happening about three times a month now and its starting to scare me. Please give me some type of answer thats all I need. My dad wants me to go see a doctor, he told me that one of his cousins had the same thing happen to him as me and he died from it. my dad is scared that it might run in the family and wants to try and stop it before it gets worst. so if you have any addvice then please let me know
