Any Suggestion For Waking With Difficulty Breathing, Lightheaded, Dizzy, Sweating, Muffled Ears?

last night was the second time in two months that I've woken up with difficulty breathing, very light headed and dizzy, excessive sweating, and my ears sound muffled followed by an almost screeching sound. It only lasts for about 10-15 minutes. After I start sweating profusely, I can feel my heart thumping throughout my whole body. I can't walk or see right when this happens. Can you give any insight on this?

Hello!

Thank you for asking on HCM!

Your symptoms seem to be caused by anxiety or nightmares. Have you measured your blood pressure during these episodes?

The lightheadedness and excessive sweating seem to be related to an autonomic reflex.

I recommend you to consult with the GP for a careful physical examination, and perform a routine blood test, kidney and liver function tests, resting ECG, chest x ray, blood electrolytes and closely monitor your blood pressure.

A polysomnography may be necessary to exclude possible sleep disorders like nightmares which are associated with an autonomic overreaction.

Hope to have been helpful!

Greetings! Dr. Iliri
