Hello,
Tremors are commonly caused due to general weakness,
stress,
fatigue, emotional distress, alcohol or drug withdrawal. Some developing pathology like MS or Parkinson's disease can be a cause.
Get your daughter physically examined. Get investigations, CBC,
Urinalysis, X-Ray(knee & leg), MRI done to evaluate the factor causing it.
Thyroid dysfunction can be a cause, let her do regular exercises & maintain weight. Being
overweight can cause tremors.
Treatment can be done by medications & surgery depending upon the severity of the illness detected.
In the meantime, let her have adequate sleep, nourish her with home made food, help her stay away from any kind of emotional or other stress.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nupur K, General & Family Physician
