The headaches could be due to a number of reasons, but one of the big causes could be your blood
pressure. High blood
pressure, low blood
pressure, wildly fluctuating blood
pressure, and blood pressure medications may all be playing a role. If you don't already have a primary care doc to help you with this, consider getting one as this may be a little out of the league of neurologists. If you have a BP cuff at home or something to measure it, consider starting a diary.
