This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
This is little concerning.
When you push down on your neck pulse, you are effectively stopping the blood flow through the carotid blood vessels.
Carotid arteries supply your brain blood vessels including the ear ones.
Hence, there is increased turbulent blood flow into your ear.
This can be caused by the infection commonly.
Or this can be an aneurysm or a tumor.
Less common cause but should be looked into.
You should see your doctor and request for a MRI scan of the brain to rule out aneurysm and tumor.
It was my pleasure to help you today.
