"Everybody gets that sometimes, even from sleeping on a pillow," Martinez said. "I hope mine is not any worse than that. I felt it pinch when I threw that pitch to warm up. I don't want to aggravate my arm or something like that. I don't want to take chances."
Martinez said he plans to see a chiropractor in the next couple of days, but he sounded like he thought he could make his next start on Friday against the Brewers.
