Can I follow-up with the above question. I am still trying to get an answer as to what caused me to blackout- I have been to the neurologist, who did blood work--(only deficiency was vitamin B-6) and alos found out I a have a mild case of Neuropathy. He said he didn't think the blackout was vasovagal syncope, but couldn't tell me what he thought was the cause-- He said sometimes these things happen once in a lifetime. Also discovered C-3-4 and C5-6 there was a mild desiccation and disc space narrowing. a disc protrusion and focus of annular fissure indenting the anterior cord. --He didn't think this could have anything to do with the blackout. Regarding the funny feeling in the back of my neck, maybe the reason was the disc protrusion. I am really looking for someone that can make an opinion as to what caused my blackout. The day before the blackout, I had very little water, a lot of stress, little sleep the night before and the evening before the blackout, I had several drinks. I need to get to another Neurologist for an opinion (I don't consider no opinion an opinion) . Anyway, let me know your thoughts. And you folks do Referrals. I am in the Ontario, Ca area.
