I just got back from a 2 month work trip where I was anxious every day to the point of panic attack a few of those days, just something I am living with and working on. but I have been home for 2 weeks where I usually am great and was swimming at the gym when my chest felt heavy..no pain just hard to get a full breath, I was getting air fine but it seemed labored. this induced a panic attack and since every day I have felt at times heavy chested, swollen at the base of my neck and fatigued of course this is causing more anxiety but is there something seriously wrong. I have never once felt pain and my bp is fluxuating between 120/80 to 140 over 87. I have been afraid to workout since. I went golfing and the symptoms were minor but I did feel out of breath very easily
