@mandy there are varying levels of migraine w/ or w/o aura. I would try and see your PCP or a neurologist about this. They can prescribe medication to prevent migraines and headache from occurring, as well as meds to help with symptoms at onset
@mandy or at the very least, one of those doctors could work-up what might be causing the headaches all the time, get imaging (CT or MRI) if necessary. Regardless, I hope you feel better!
