Nic Batum is back in the Charlotte Hornets lineup after receiving one of the scares of his life. Batum missed two games last week with a migraine headache, a malady so severe that he couldn’t get out of bed for four days. “I was scared, worried,” Batum said Saturday after the Hornets guard scored eight points and grabbed 10 rebounds in his return, a 98-93 victory against the Washington Wizards at Spectrum Center. “I couldn’t think. I couldn’t eat or drink anything. It took me out of everything.” The migraine came on March 12, the morning after the Hornets had played an overtime game against the New Orleans Pelicans. “I couldn’t move,” Batum said. Batum said he had suffered a concussion four years ago, but the pain from that injury was nothing compared to the migraine. Compounding his worries was the recommendation from Hornets trainer Steve Stricker that he have a brain scan.
