In this sentence, "Toni has no article terrible stomach ache," the absence of an article ("a," "an," or "the") is appropriate because we are referring to a non-specific, general stomach ache. Articles are typically used to specify whether something is definite (the) or indefinite (a/an), but in this case, we are not specifying any particular stomach ache, so no article is needed.
