Your symptoms are very disturbing , and if you have not visited your doctor since he wrote the question a week ago, should do so immediately. Hypertension (high blood pressure ) is a risk factor for cardiovascular disease , people with hypertension are more likely to suffer heart attacks than people with normal blood pressure. His dizziness, chest discomfort and neck pain are very likely manifestations of angina , may be warnings that may be about to have a heart attack. Do not delay , seek medical attention as soon as possible. good luck
