Appeared tired around 2:45 PM.  Did not eat dinner and went to bed at 5:00 PM.  Woke up at 6:00 PM complaining of dizziness, not feeling good, and of shaking. I (mother of patient) noticed that patient exhibited what appeared to be myoclonic jerks.  I noticed this as he was sitting and walking.  Temperature was 97.5 axillary.  Pulse 75.  No sweating.  Forehead felt slightly warm to the touch.  He was awake and oriented to person, place, and time, but stated he did not feel good.  He looked tired.  I (patient's mother) called the pediatrician's office and was told to take him to the emergency room.  Taken to the emergency room at 7:00 PM.  While patient was sitting in the emergency room waiting to be seen by the physician, I (patient's mother) noticed what appeared to be myoclonic jerks again, accompanied by patient's complaint that he felt very sleep.  He started to close his eyes and I physically stimulated him to keep him awake by talking to him and massaging his head and shoulders. Patient was examined by emergency physician at approximately 7:30 PM.  Pulse was 65 according to emergency room automatic blood pressure machine.  By 8:15 PM, patient stated that his dizziness was decreased and that he felt better, but he said that he still did not feel "right" like his usual self.  I (patient's mother) noticed that he no longer exhibited any jerky movements by this time. I took his pulse by palpation and it was 60. Emergency physician noted that while patient was "distracted" by activity, such as standing and sitting, there were no jerks.  Patient was sent home without treatment and was told to follow up with primary care provider in the morning.  Patient has intense burning feeling inside body, feels like volcano internally.
