Hello! Welcome and thank you for asking on HCM! I carefully read your question and understand your concern. Your symptoms seem to be related to tension type headache, which is a chronic type of headache, usually associated to migraine. The fact the paracetamol tablets are not helpful is a little concerning, taking into consideration the fact that you suffer from polycystic ovary. I would recommend performing a brain MRI study coupled with angio MRI to exclude possible intracranial aneurysms, which could lead to migraine type headache. You should know the polycystic ovary imposes a higher risk for intracranial aneurysms. Besides, I would recommend you to monitor your blood pressure. The fact that you take Betacap before sleep, may be the reason that your headache improves during the night. A high blood pressure during the day could be the cause of persistent headache. Hope you will find this answer helpful! Kind regards, Dr. Aida
