I real worried about my blood pressure. I'm 23 (24 in Feb.) and the past 5mths I've notice my heart POUNDING. Not always fast just REALLY hard. My mom bought a blood pressure cuff thing and I've been monitering it. Today it 131 over 81 over 120, then like 5 minutes later it was 115 over 71 over 115. I'm clueless about what's good or not. I've also noticed that lying down doesn't make a difference. Sometimes when I wake up in the morning and roll over it starts beating incredibly hard for about 20 seconds, then just a little hard for the rest of the morning. It mainly is like this for the first 3hrs after waking up; rarely at night. My mom and I decided to lower my adderall to see it changed and it really hasn't, but I've been taking adderall for YEARS and it never did this in the past on the same dose. I've been having chest pain but I don't know if its heartburn or not, and I'm on prevacid. It feels like someone is stabbing my heart, it just hurts and its hard not to show it.
