<s>[INST] I have a continuous spasm in my left cheek, and my right arm is starting to go numb. I had unexplained seizures 6 years ago, but I haven't had them since. When I was a baby and got hurt I would pass out for a few seconds. Do you know why I'm having cheek twitching and my arm going numb? [/INST] Hi, I had gone through your question and understand your concernsWith such presentations in my clinic, I would first ask for MRI brain to search for any central cause ,also i prefer doing EEG FOR YOUR BRAIN TO RULE OUT THE CAUSE OF SEIZURES. </s>
