Today I Had A Nuclear Stress Test. I Started With

Today I had a nuclear stress test. I started with a blood pressure reading 117/70 67. No too surprised but even once I had a regular Blood Pressure of o the Doctor90/67 60 so the Dr. cut my incur to half a pill. But today during the test it went to 110/67 60 then the last one was 90/60/57. I go a terrible headache which she ask if I was use to Coffee. I cut back to 1 cup of reg. Coffee as I take 150mg of Thyroid and just do not have any pep. The coffee seems to jump start me. I do not drink Soda's and tea. I have just stuck to water the rest of the day. What I want to know is isn't my blood pressure to go up during exersise? When I work outdoors I am fine until I get stopped then I break out in a terrible sweat. I am not Diabetic either. Heart trouble is in my family history. Thank you for easing my mind with any help before I have to wait 3 weeks for answers. Again Thank you, PJ
