I did not have MVD as an option but I did get twitching ALLOT . I thought others could see my lower lip and right cheek twitching and spazing out but they could not see it . I was told it was /is nerve misfiring. I dont have it happen so much any more. I too also take vit B12 since I first broke lower jaw in 99. It was one of the first thing dr. reccomended for nerve growth.Oh for some T.N folks numbness is better then the eletrical zapping but both suck. Glad Ella got back to you. Take it one day at a time. Sending low pain and some good days . Peace. BMW
