Hello. Thank you for your question and welcome to HCM. I understand your concern.
Well, if the cardiac check-up came back fine, then we can exclude cardiac origin as the culprit of this situation. You are young to have
angina, though it is not impossible. Therefore, I would recommend you to do a cardiac
stress test, which has a high probability on confirming or excluding the coronary
artery origin of this problem.
On the other hand, the other problems you reported, can come from a common situation which is called deviatio septi nasi. Septum nasi is located inside the nose, on the upper side, and is found deviated or deformed in a large number of people worldwide. It is totally benign and harmless. But, when it is deformed, it blocks the discharge route of one of the
sinuses. It results in liquid accumulation within the sinus, its walls become inflammated, hence the headache, nose congestion and
sinusitis. If this happens often, I would recommend you to see an otorhinolaringologist (ENT doctor) and discuss the possibility of repairing this deformation.
I hope I was helpful with my answer. Take care.
Best regards,
Dr. Meriton
