Patient: I’ve been blinking since I was 12 years old, my family thought it was just a habit and that I would get better when I grew up and controlled it myself, but now I always blink involuntarily, and I blink when I talk to people, and I blink more often than not, and I don’t even know it until my friends and family always say so, but I can’t change it when I’m old, but I can control it, and I can stop blinking as long as I pay attention to it. But that will be very tired, a little inattentive or thinking about the problem a little into the forget again, if I do not have the next person to tell me, I do not know that I started blinking again. And if I pay special attention to restraint, I feel weird about my eyes. It seems to itch a little, is there something wrong with it? /Could it be a muscle cramp or vitamin deficiency in the face? I saw an ophthalmologist at a tertiary care hospital in Guilin in 2006 and took a week’s worth of medication, but I was not cured, and then the ophthalmologist asked me to see a neurologist, which I did not do.
