Hi, I am a thirty year old female. I suffer from debilitating anxiety and panic attacks. As a child, I had 2 febral seizures. A few days ago i felt a little off all day (faint, back pain and chest pain,very anxious, terrible migraine) and ended up having a grand mal seizure. I went to the er and they did a CAT scan, blood work, a urine sample, and EKG. All were normal. I had taken zanaflex about an hour before i went into the seizure. Is it possible zanaflex could have caused it? I am going to see a neurologist soon but just wanted a professional s opinion, Im very worried, and having anxiety as it is, Im under a great deal of stress. What is your opinion? Thank you for your time. -Whitney
