You have a killer migraine that renders you completely powerless to even sit up without feeling nauseous. I really really hate that.. even more so when I was about to start working! It was one of my bad ones yesterday where the throbbing was so intense my eyes involuntarily tear up, my body temperature feels warmer than normal (yet it is) and the painkillers don't work. Everything becomes sensitive.. the light.. the sound.. and the no-way-to-get-comfortable-on-your-pillow feeling..
