Hello! Thank you for the question on HCM ! I understand your concern! I think that your headache may be migraine or a sinusitis. I wouldn t exclude a drug induced headache which is caused by chronic intake of painkillers. I would like to know if you have nausea, vomiting or gait problems or fevers. A brain lesion which raises the intracranial pressure would cause progressive headache and other symptoms like the above mentioned. I recommend you to consult with the GP for a careful physical examination. A routine blood analysis and a brain CT scan may be needed. Hope to have been helpful! Greetings! Dr. Aida
