[|Human|] I have this pulsating at the top of my head, it comes and goes but now it has been there for 24 hours. It seems like the scalp is pulsating and if I put my hand on it I can not feel it anymore. It seems to be tied to my heart rate. Do you know what this can be.
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms may be related to a migraine. What are your actual blood pressure values? Uncontrolled high blood pressure may be the cause of this symptomatology. If your blood pressure is within the normal limits and this problem persists, I would recommend consulting with your GP for a careful physical examination and a brain CT scan, to exclude possible intracranial vessel disorder (including an aneurysm). Hope to have been of help! Best wishes,
