I Have Just Been Changed To Hazaar Blood Pressure Med

I have just been changed to Hazaar Blood Pressure Med for recall of Sub for Diovan. My previous dose was 165-25 and the new one is 50-12.5. I have had a headache and neck pain and blood pressure went up.... Dr. said to take 2 Hazaar, I did that, she also has me on 25mg of Metripol in evenings.. Pressure still up and headache still exists ??
