My 18-1yr-old sister has been having migraines since she was 10. In fact, she has had one almost every day for about a month. She does have anxiety issues, however she hasn't been diagnosed w/ GAD (generalized anxiety disorder) yet. Recently while driving she had to pull off the road due to a severe migraine and light-headedness and once at work her migraine was so bad that she could not respond when asked a question. She knew what she wanted to say but she just couldn't get it out. Today not only does she have a migraine, but she has a metallic taste in her mouth and her throat is throbbing. She does have a cold (which she gets often) so that could be the reason her throat throbs, but what is the metallic taste about and what can she do to stop the migraines and anxiety?
