Vikings wide receiver Percy Harvin says he's migraine-free. He hasn't had a debilitating headache in five or six months. "This is the best I've felt, probably, since I've been in kindergarten," Harvin said. Harvin was reluctant to go into much detail, but is cautiously optimistic he's found long-term relief from a health issue that has dogged him since childhood. "I met a couple of doctors," he said. "There were a couple of things they found in my neck that I won't get into - some things they found and fixed, along with diet and the rest of the things that can cause them. "It's been great, and knock on wood, it'll continue."
