My son who is almost 6 has been exhibiting very odd behaviour over the last week and a half. Although, he has always been a very verbal, outgoing and social boy,he has always been a little volatile, with a lack of impulse control and quick to anger since he was about 4- maybe even before. He started having what I now realize as ticks probably about 5 months ago- 1st licking fingers, then blowing on fingers, then spitting, then eye blinking. Last weekend he started staring blankly while moving his arms slightly to the side and tapping them to his side. He has been doing numerous tic like behaviours in the last week, but most alarmingly over the last day or so, he has complained about the loud noise in his ear sometimes, and how his voice sounds really loud and he wants it to stop. It then seems to go away after about a minute or so. Needless to say I am terrified about this latest development. We have an appointment with our pediatrician tomorrow, but I am wondering if anybody has experienced or heard of this symptom before. Thanks for any info.
