Something this serious you need to have a second opinion. If the second doctor agrees with the first doctor that you should have surgery, then you need to. I wish you all the luck in the world, a speedy recovery if you wish to have surgery and may God Bless you:)
The Carotid artery
when a person has a stroke it can be from blockage in 1 or both of the carotid arteries in the neck.
The cause of carotid stenosis is the buildup of plaque on the inner wall of the carotid artery. The reduced blood flow to the brain and the blockage of other arteries following the release of emboli can cause a stroke.
The radial artery, carotid artery, and the brachial artery can be used to feel your pulse; but only if you feel them with your tongue. The easiest to do the radial artery, located in your elbow.
The physician must be sure there is no evidence of blockage in the carotid artery before performing the procedure. Massage in a blocked area might cause a clot to break loose and cause a stroke.
Carotid artery occlusion blockage means that there is complete blockage of the artery. This is very serious, as complete blockage of the artery can cause a stroke.
The Carotid artery
If the blockage is impinging on the vagus nerve, yes a blockage in the carotid artery can cause nausea. However, most common signs would include feeling faint, difficulty thinking (particularly for complicated or long-term tasks) and lack of energy.
If the carotid bodies are removed during the process the respiration rate may not increase as effectively in response to low levels of oxygen. Carotid artery disease occurs when the major arteries in your neck become narrowed or blocked.

a procedure that measures the pulsing of arteries behind the eye, which can show carotid artery blockage.

The radial artery, carotid artery, and the brachial artery can be used to feel your pulse; but only if you feel them with your tongue. The easiest to do the radial artery, located in your elbow.
A stroke, caused by reduced blood and oxygen supply, may be an indication of severe blockage in the carotid artery. Less severe blockage may still cause "mini-strokes" or transient ischemic attacks (TIAs)
The physician must be sure there is no evidence of blockage in the carotid artery before performing the procedure. Massage in a blocked area might cause a clot to break loose and cause a stroke.
I would think that if BOTH carotid arteries have (at least) 70% stenosis (narrowing) due to hardening of the arteries (a build-up of plaque and fat), you could cause dizziness... If you have this problem you need to see a vascular surgeon immediately for evaluation and treatment!
The lingual artery is the branch of the external carotid artery that supplies the tongue with oxygenated blood.
