My g/f as Vasovagal syncope, basically she can faint without any real warning. On friday she fainted getting out of bed in the evening and smashed into the metal frame, and when she came round had zero feeling in either of her legs. Phoned ambulance and spent the next 4 hours waiting for the doc's to tell us hour serious it was. Lucky it was nerve shock rather than damage, and one leg came back to usable in about 2 and a bit hours the other one still wasn't right as we left the hospital at 5 in the morning, she could walk on it but it hurt a lot. Scariest 4 hours of my life waiting for xrays to make sure her spine hadn't been damage etc.
