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.
