Had migraine & vomited last night, better this morning but have question, if this was from gallbladder attack,would i have also had abdominal pain? i only had severe head pain and vomited, is it possible to not have pain in abdomen w/ gallbladder?

If you have a concern regarding gallstones or cholecystitis, have your doctor evaluate this. Migraines can co-exist with gall bladder issues. The latter usually causes distinct abdominal discomfort regardless of the migraine headaches. The two co-morbidities would be treated separately and differently.

Headache and vomiting are more symptomatic of things like migraine and other causes. Anything is possible in medicine but chances of that are extremely low to nil. Hope you feel better.
