Dear Doctor, I am having high blood pressure since last 3 years and taking adalat retard 20mg and Zestril 20mg tablets daily but still my blood pressure is always between 170-180 high and 90-110 low. I have consulted a cardiologist and did many tests list ultrasound for heart, ECG, blood test, Sonography for kidney but all seems to be normal. whenever I m nervous or angry I start shivering and my heart beats are extremely fast so fast that I can feel a vibration in my body. Please suggest me what treatment I can do. For your information I am based in Kuwait. my age is 29
