I am 32 year old female, I weigh 175lbs and I am 5'5". For the past several months I have had issues with shortness of breathe. I have been to a cardiologist and had a stress test done to rule out my heart and all test came back that my heart was in excellent condition. I have had x-rays done of my chest and nothing has ever come up on the resluts. History: I have worked very hard the past 1 1/2 years to loose weight and get into better shape. Which I have accomplished by leaps and bounds because a year ago I my starting weigh was over 210lbs. I exercise for an hour 3 to 4 times a week. I had to have had my gallbladder removed last year, October 2010 and felt wonderful afterwards. Within 4 months I started feeling the reflux issues again. Had a scope done and found that I had a small Hiatel hernia and was diagnosed with GERD. I just worry because I have this what I call sore feeling in my chest. When I breathe it hurts...its not a painful hurt but like a soreness hurt (i feel like I have worked out my chest muscles extrememly hard) I recently noticed also when I went swimming for the first time that getting into the water made my chest feel like I had someone sitting on top of me and made it that much harder to breathe in the water. I am just concerned that somethng else could be going on or have I done something and strained something that could be causeing the constant soreness, but that still doesn't explain my shortness of breathe unless that is a result from the soreness and I am just not able to breathe in as deep because it hurts.
