Hello! Thank you for asking on HCM! I carefully read your question and understand your concern. Your symptoms could be related to a sinus infection. I would like to know your actual blood pressure values. You should know that high blood pressure could also explain headache associated with nose bleeding. I recommend you to closely monitor your blood pressure and consult with your GP for a careful physical examination and some tests: - a sinus X ray study - lab blood tests (complete blood count, inflammation tests). You should discuss with your doctor on the above issues. Hope to have been helpful! Greetings! Dr. Aida
