Hi everyone! I am trying not to google so instead I am posting here. I am a 23 year old female with horrible health anxiety for the past six months. Lately I have been getting really bad chest pain (GI doc says I have acid reflux and gastritis) as well as nausea and gas, but I also occasionally feel dizzy/lightheaded which I chalk up to anxiety. Does anyone think this could be a heart condition?? I took a fitness test to apply for a gym membership about a week ago and passed after she checked my exercise pulse, resting pulse, blood pressure, etc. Would something have shown up? Also I usually exercise about an hour a day, treadmill, elliptical, etc, without any noticeable increase in chest pain. What are my chances at my age and sex??? Need some reassurance and also help cuz I am NOT GOOGLING.
