I am a 24 year old female. I am 5'7 and about 160 lbs and have always been healthy. I have no major medical problems, I eat right, and I exercise. For about 3 months, I have been experiencing chest tightness especially at night. It is worst around 2-4 in the morning. My chest feels tight on the left side. When I put my hand on top of it and apply a little pressure, it feels better. As soon as I take my hand off, it goes back to feeling tight. I am a little freaked out because, of course, when I put my hand on top of the area, I can feel my heart beat so I know it's really close or right on top of my heart.
I do consider myself to worry more than most people. Sometimes I worry so much, my stomach hurts. I have been under more stress than usual for a while. I had chest tightness once before I got married. When I went to the doctor, he told me I was just nervous about the wedding, and it would go away after the wedding. He was right. However, I remember that chest tightness being in the center of my chest, not on the left side. Do you think this is a heart related condition or just stress? Thanks!
