<s>[INST] My six year old son has had transient tics in the past throat clearing that lasted about 2 weeks and then shoulder shrugging that lasted about 2  months. He has started with a blinking eye tic , but I noticed the last few days that his eyes are tolling back a bit while the blinking is going on . Do you think this is more than smoother tic . [/INST] Hello,It is hard to say but in a six year old tics like this need to be evaluated by a pediatric neurologist. They can make sure that there is nothing severe going on in his brain that is causing these ticsRegards </s>
