I have a migrain and a sour stomach ache at the same time, i can't eat and i get nauseous as well . whats this mean?

Migraine headache: Migraine headaches used to be called sick/abdominal headache since some of the symptoms associated with migraines are nausea and vomiting. Preventing migraines is the best strategy with this type of headache. Consulting with a neurologist is the best first step. Improvement may be as easy as supplementing your diet with pharmaceutical grade magnesium.
