migraines are vascular headaches and not all headaches are "migraines". migraine does not mean a severe headache it is just one type of over a hundred different kinds of headaches. the type of headache you may be describing is one of the more common types. a muscle-tension headache but the pain under the breast is not a typical symptom. muscle-tension headache can certainly come from the neck. since you cannot be blindly diagnosed over the internet i would suggest that you see your medical provider for a proper examination.
