Question: My doctor is considering a study for me…..I wake from my sleep with a headache and my blood pressure has increased. When I am awake there is not a blood pressure problem and I do monitor frequently. I am a big dreamer and not always pleasant, usually a crisis and I have thought this could be the reason for rise in headache and blood pressure. When I awake with the headache and take blood pressure it varies but is over 140…then in about 3 to 5 minutes goes down to less than 120. Anyone else experience this?
