Hello! Thank you for asking on HCM! I read your question carefully and understand your concern. Your symptoms seem to be related to high blood pressure and migraine. I would exclude any possible stroke related to your symptomatology. You should know that high blood pressure can cause vascular type headaches, mimicking migraine attacks. The sore spot on your head is related to a temporary dysfunction and vessel constriction in that area from the vascular headache and high blood pressure. I agree with your doctors that the best therapy to control your symptoms would be aspirin (for the prevention of possible vessel occlusion related to the constricted vessels) and arrangement of your antihypertensive therapy. Regarding the palpitations (heart fluttering) that you have been experiencing I would recommend performing a careful physical examination, a chest x ray, an ambulatory 24-48 hour ECG monitoring and some blood lab tests like: - complete blood count - thyroid hormone levels - kidney and liver function tests - fasting glucose - blood electrolytes , etc, to rule in/ out any possible cardiac arrhythmia and investigate for any metabolic cause, related to this clinical scenario. If all the above tests result normal, anxiety should be taken into consideration as a possible factor contributing in high blood pressure and tachycardia. Hope to have been helpful! Best wishes, Dr. Iliri
