Is it normal to get a pain in the head while doing Body Flex exercises?

Body Flex are deep breathing exercises where you take in a deep breath then exhale real hard, then hold it while sucking in your stomach. Anyway, there's one extra step where while you're holding your breath with your stomach sucked in, you turn your face upward to stretch & tone the double chin area. Well when I do this part, I get a pain that shoots to my head; like a severe headachy pain. Has anyone else had this happen? Any explanation as to what causes that?
