My mother was facing random vibrations in head from 6 months to which she was prescribed zincumate . Now from one month vibrations are gone but her neck twist to left and shakes probably like cervical dystonia. I went to Dr. Navneet kumar prescribed who prescribed her few medicines namely ( bexol , becloze , cynocal, octane) and ask to meet after one month. It is early stage of disorder and i fear symptoms may get worse.
