as you have not mentioned you blood pressure i would assume you to be in stage 1 (mild hypertensive)
systolic bp between 140-159 ,diastolic bp in between 90-99
you can start taking a
calcium channel blocker like
amlodipine for headache you can take tab
vasograin twice daily ( over counter medication)
try to do exercise 45 minutes per day
take a salt restricted diet
avoid oily and spicy food
if the headache is unilateral ( half side of head) it can be

in your case elevation in blood pressure can be because of migraine or headche can be because of increased blood pressure
