I have severe coldness in feet and hands intermittently but is present most of the day. I also have high blood pressure especially diastolic which is in the range of 130/100 to sometimes 134/96 along with flushing of face, heat, coldness in feet and hands sometimes. And these symptoms are very discomforting to me. I tried taking amlodipine or cilnidipine but those drugs didn't improve my coldness, instead the flushing worsened and coldness also worsened. They also increased my heart rate to 120/min,  also caused palpitations, tension in neck and headache. I am now taking nebivolol 5 mg/day and it somewhat helps with bp. But during stressful work or cold exposure or sometimes simply sitting in room, my feet get cold and hands too. And diastolic always remains high. How to treat this diastolic hypertension and coldness in extremities?
