Can't find any blood pressure med that doesn't cause horrible splitting headache! have tried numerous. the severe headache then raises it higher!

Consider: Beta-blockers, some are fda approved for migraine. There is also some promising medical literature for the use of candesartan for headaches as well.

Can be solved: In my opinion, it is almost a certainty that you have a tendency to experience migraine headaches from a variety of medications, as an adverse effect. Best solution is to see a neurologist, and prevent headaches in the future. Although there are many prescription meds, some otc useful preps include butterbur, feverfew, riboflavin, magnesium, co-q10. Perhaps acupuncture or Botox might work well.
