Welcome on Chat Doctor! I understand your concern and would explain that your symptoms are related to high blood pressure. I would recommend you to closely monitor your blood pressure frequently during the day for a prolonged time up to 7 days and refer those values to your attending physician. In case your blood pressure values are above 135/85 mmHg most of the time, this would indicate arterial hypertension. Further tests are needed to exclude other secondary causes of high blood pressure: - a chest X-ray study- a resting ECG-some blood lab tests (complete blood count, fasting glucose, blood lipid profile, kidney and liver function tests, blood electrolytes, PCR, sedimentation rate, thyroid hormone levels). You should discuss with your doctor on the above issues. In case of uncontrolled high blood pressure you may need to start antihypertensive therapy. Hope to have been helpful! Kind regards,  </s>
