I'm 30 and have recently found out I have very high blood pressure first it was 219/132 when I got into the docs it had gone down to 146/110 I've been on rampril for 4 days now blood pressure still high above 100 on the bottom number it goes between 132/100- 165/124 still have a really bad head. I'm just wondering how long it took for people BP to go down.
