Hi and thank you for the question. I have had off and on problems with Chest pain and pressure. Two nights with in the last 5 days I have woke up around 3:00am with a burning pressure in the center if my chest and slightly to the right. I have been taking 2 15mg Prevacid a day for a full week and one a day for a bout a week or two before that. It seems to do nothing or make it worse. I have always had anxiety and for a long time was obsessed with there being a problem. I have had sever echos, ekgs, and 2 stress tests. The most recent was in September of 2012. I am 32 year old female with normal bp and cholesterol and weigh 111 5'4". My only risk factor is than my mother had heart attack at 53. She was a heavy smoker and that's the only person on either side with any cardiac issue. My father has severe reflux as doesn't brother. My concern is why the previcid isn't helping and almost seems is making things worse. Could this be cardiac related and not GI? Way do I do next? My drs just think I'm a hypochondriac and I do see a therapist for the anxiety. This chest pressure and burning is real though. I have never woke from my sleep with pain until now. The pressure has been almost constant for a full week with few breaks and I am also belching alot. Some times it feels like its getting stuck halfway up my esophagus and never makes it out. Is this air or acid? Please help the best you can over the Internet because my dr is useless at this point and everything is anxiety to him. Thank you!
