I've been having a few migraines a year for years now. Last spring I had a 3 day migraine. This week it's happened again. I wake up at five in the morning with one, and by dinnertime it's gone. Right in the back of my head. Today was the first day without it in 3 days. The back of my head is really sore though,like a bruise. Has anyone had any experience in dealing with them? I've been given zoloft, but haven't used it yet.
