Josh Hader had a sore neck so he tried to stretch it out, accidentally popping it. Next thing he knew, the left side of his body started to go numb. He went to the kitchen for an ice pack but couldn't walk straight. "I kept walking at almost a 45 degree [angle] to the left," he said. Dr. Vance McCollom, who treated him at Mercy Hospital, said the stroke was life-changing but could have been worse. "When he popped his neck he tore arteries that go to the bone of the neck, where the neck joins the skull at the base of the brain," he said.
