I Have Experienced A Spike In BP Associated With Blurred

I have experienced a spike in BP associated with blurred vision twice within the last 6 weeks. It happened today and the BP was 170/91. I took a chlonodine and it came down in about an hour and the blurred vision went away. BP is normal this evening. I take HSTZ 12.5 ng mornings and Azor 5/40 at night. The blurry vision is very frightening. Mr doctor says a spie in BP would not be associated with blurred vision but is sure seems to be. What is your take on it?
