Our 15 year old daughter had a sore throat, which started on September 12. It turned into a cold, however, a week ago Sunday (today) she woke up to her jaw involuntarily moving up and down, like a tremor. It went away late that morning but then in the middle of the night, Monday, she woke up with the tremors again (she woke up to get water and noticed the tremor was back). It has been constant since that time. We were first told TMJ. All of the blood tests that have been run by a family doctor and neurologist have been normal except her Vitamin D was low (20). She s periodically nauseas throughout the day, doesn t eat much and takes small cat naps, which she hasn t done for years, even when she s been up late with friends. The tremor of her jaw is constant unless she clamps her teeth together and it is less if she opens her mouth really wide.
Hello! Welcome on Chat Doctor ! I read carefully your question and understand your concern. Vitamin D deficiency may trigger this clinical situation. Anyway, I recommend performing a brain MRI and an EEG to exclude possible seizures (although her tremor continues through the day). Blood electrolytes (including copper, magnesium and manganese). As all started after a sore throat, I would also advise performing antistreptolysin O antibodies, to exclude possible Chorea Minor.  If all these tests result normal, I would recommend consulting with a psychologist or a psychiatrist. Hope you will find this answer helpful! Best wishes,
