I am a 25 year old female. I do smoke cigarettes, but cut down to 3 a day. I just moved out to the West coast from Florida and having chest pains. I have gone to the ER twice within the last 2 months. My blood tests, EKG, and chest xray all came back normal. I cannot deicer if this is severe panic attacks. My chest pains are centered or under the breast bone. (Both sides) my feet and hands get super sweaty. I feel like I cannot breath because I have a heaviness on top of my chest. My beats per minute was between 45-60. I sometimes wheeze. Tonight, my stomach felt like I had acid refluxed and I actually threw up. Doctors say I am fine, but I always think I may be having a heart attack. I feel like my throat closes in. I am still having pain.
