hi. noted history of weakness and shaking of arms and legs of your child. does she have other accompanying signs and symptoms, like fever, gastrointestinal disturbances? have you observed this happening only after you told her about your condition? is she having adequate nutrition/food intake? it is best if you bring your daughter to a doctor, preferably a pediatrician, for physical examination and clinical evaluation. yes, it may be an anxiety disorder. but other pathologic condition such as neurologic and infective causes must also be ruled-out. diagnostics and management will be directed accordingly. for now, talk to your child, keep her hydrated and well-nourished and ask if she s feeling anything other than the shaking of her limbs. hope this helps. good day!! ~dr.kaye
