Hi my daughter 2+ yrs from concussion gets the shakes if she is cognitively working too hard. She has had 2 major set backs over this time. What has helped with her headaches and shakes is acupuncture. During the procedure my daughter's headache almost immediately goes away and her shakes subside. here is the URL for the doctor that she sees...Dr Rozenn might be able to guild you to a type of acupuncture that would be beneficial to your gf. http://acupuncturesantacruz.net

My best,
