I blackout like 20+ times a day for the past few years. when I blackout i get dizzy, lose my sight, my whole body, face and mainly my lips go numb, i sometimes pass out or fall because i cant feel my legs, when i come too, i have a really bad headache that lasts a few second or a couple minutes. Ive had my blood pressure and blood sugar checked and there both fine i don't know what else it could be
