it sounds like you are having symptoms of gerd (or acid reflux disease) with your age and history and the length of your symptoms it is highly unlikely you are having a heart attack. if you have a history of anxiety and heartburn it could very well turn into gerd. i have acid reflux and the symptoms your describing coincide with gerd. i find taking an extra strength zantac (150 mg) once every morning keeps me from experiencing any symptoms. if that doesn't help or doesn't help enough you can always speak to your doctor. there are proton inhibitors they can prescribe you that will work much better. (proton inhibitors slow the production of stomach acid) however if you are having any other symptoms or your current ones get worse i would definitely contact your doctor right away.
if alka-seltzer helps me does that mean i'm not having a heart attack? . i am a 28 year old woman i don't drink or smoke. for that past three days i have been having pain in my chest and a warm feeling behind my chest and have been having gas also. it only stopped after i took some alka-seltzer and only worked for a few hours. i also have a history of panic attacks and heartburn.
