My friend experienced tremor symptom in January after many general medicine doctor consultation he goes to neurologist for tremor and twitching problem (between period twitching also starting ).neurologist recommend b12 test in which vitamin b12 level is 82 pg. He started me oral tablet and said you have peripheral neuropathy. Even after 6 months twitching won't stop. He goes to another neurologist who conducted emg test that test result was complex repetitive discharge and said you have benign fasciculation syndrome but it may be coveted into motor neuron disease .please tell everyone is scared.
