I have had numerous heart checks recently since i was experiencing a squeezing chest, shortness of breath, and a tightness in the middle  when moving my arms i feel it more tight and also got a pain in the heart stomach area. I had a holter monitor and an echo stress recently and also previous ER visits were all normal and the tests were ordered and reviewed by a cardiologist im also in my late 20's. I suddenly felt it again a tightness in chest squeezing togther and pain in my heart i got scared and panicked and also felt like i will pass out. I have health anxiety and was prescribed prozac and klonopin but stopped due to some side effects. Can anxiety cause this has anyone experienced this squeezing chest pain and pain the heart area, I also suffer from GERD
