I've had low pressure for many years, low sugar as well. I'm anaemic to the point I receive iron infusions once or twice a year and B12 shots on e a week. Lately I've had headaches with dizziness to the point of stumbling or falling. My blood pressure in the last week has been 88/66, 121/48, 100/69, 117/69 and so on. Can you give some advice concerning this problem.
