Thanks for your health concerns. Indeed, high blood pressure
is a cause of headache, particularly occipital in the back of the head. If you are young, most likely your doctor ordered blood tests to see if there are any secondary causes for high blood pressure; if blood pressure continues to be elevated despite a trial of reduced salt consumption, perhaps weight loss
if you are overweight
, then medications might be needed and prescribed by your physician.
Hope this helps, truly yours,
