I've had very bad anxiety over the past year and have suffered from a tension headache since Jan 2011, my head hurts pretty much everyday, so does my neck and back. When I go outside the brightness makes it so much worse. I've been passed from doctor to neurologist and osteopath to massage therapist but it's still not sorted. They tell me to relax but how can I when I'm always in pain? Painkillers hardly ever work. Does anyone else have this and have you found anything that helps?
