My concussion threshold hasn't returned to normal... yet. I had to leave Southern California to move back in with my mom in the Northeast because I can't take care of myself. I saw 2 headache specialist that I wasn't happy with. Finally I went to a headache Clinic and I found my current doctor that I love. Is there a Mayo Clinic in Southern California? I've heard pretty good things about their treatment of migraines. It took a couple years to find the right meds for me. Methylergonovine is what seems to be having the best effect now. But everyone's brain chemistry is different and it may take your daughter while to find the right fit. I hope that the two of you had the strength and patience to fight through this struggle. Wishing you both the best!
