Hi, I am 40 years old, 163cm and 85kg. I have high blood pressure and high cholesterol, currently controlled within safe limit with daily medication. I am experiencing left ear drum cum left nasal blockage together. When I bend my head down, backward or to the sides, stretching my neck, 90% of the time both the blockages will be cleared immediately, and will block again immediately when my head is backed to the upright position. What is the cause of my problem and what should I do. Regards.
