I've never gotten a migraine before, but my mom has, and let me tell you, it is scary! One time it was so bad that my mom couldn't even move because the pain was so bad. It sucks cuz there's very little you can do about it. Whenever my mom gets them she goes to her room, shuts off all the lights, puts the trash can next to the bed (incase she hurls), and then she just lies down with a towel over her head.
She hasn't had one in a while though, thank goodness. She usually gets them because of too much stress.
