It is possible that the initial slight raise in your blood pressure was caused by the vertigo
, and not the vertigo by a raise in your blood pressure . I am not convinced by the details that you give here that it was necessary to change your blood pressure medication
. I would have suggested that you have three readings taken different times of the day with one week intervals . I also do not think that the aspirin
is to blame , continue with aspirin to prevent vascular events. Speak to your doctor about going back to your original treatment and take a salt free diet.
