Facial twitches. Be highly appreciable.

I feel numbness and tingling in my facial nerve. Sometimes numbness in my hands ,legs and other body parts. I get little but noticeable, involuntary facial expressions which is like smiling and angry. I am very tensed and had to leave my job as my colleagues were abusing and making fun of me. I think my life is ruined. I tried exercises and facial exercises which exaggerated it even further.Can u tell me that is this problem curable. And which type of doctor shall I consult. And can you also tell me what role magnesium plays in this. I consulted a physician who did not took my problem seriously and recommended me etopram and other medicines which didnt cure me.  A proper reply would be highly appreciable.
